PSB SPEAKERS
PSB 1000 STEREO SPEAKERS
"*2.5-Way" design
#...1517 / 1518
Made in Canada
Circa 1996
for sale
Very accurate and detailed sonic reproduction from these PSB 1000speakers.
Our speaker tech has completely gone through and 'Certified' these. All drivers were removed and tested individually. One of the woofer surrounds appears to have been replaced recently. The balance of the Woofer surrounds in good shape.
Cosmetically, they're in great shape. There's a few minor edge dings, (mostly to the rear edges) (see above photos). The grills were cleaned & the cabinets in great shape. The grill fames and locate pins all in good shape with no breaks or broken / missing pins. The original, black knit in near new shape. Original PSB both intact.
Next, as always they were tested with 20-20k White Noise, swept them with our AF generator from 1Hz-5kHz to find any any extraneous vibration or acoustic anomalies.
Then came our standard, 'issue exposing' and on some levels, 'abusive' test recordings. To that point, in the August 1996 issue of Stereo Review, "On the outside, the PSB 1000 resembles many other tower speakers, but inside it's as unusual as it's drivers. PSB states that the enclosure is assembled from high-density, non-resonant wood composites using rounded, extruded corner moldings that make it extremely rigid. Julian Hirsch noted "That rigidity can easily be verified by a simple knuckle test. Rapping any portion of the cabinet exterior produces a 'sharp click', striking free of any ringing or other since of cabinet resonance".  I noticed this myself, and while our tech had the cabinet apart, I was amazed at the internal structures tying the backs and sides of the cabinet together, also forming a separation from the top woofer air space and the lower woofer resonant chamber.

Our demo cuts included the following; Dire Straits' "So Far Away" from their album 'Brothers in Arms' album,
Donald Fagens, "I.G.Y." from the album "Night Fly" (awesome as it should be. Not at all brittle. Very solid),
'24K Gold Edition of Jennifer Waren's "Famous Blue Raincoat' (Overall very natural across the board. Very well balanced),
TLC's "Scrub" from their album 'Fan Mail' (did 'sub-bass' note @ 1'25" & 1'35" probably better than any speaker we've ever had. Not so much from a 'volume standpoint, but a 'quality' standpoint),
Allison Kraus and Union Station's "Baby, Now That I've Found You" (Quite natural vocals. Fretted instruments ALL very pleasing to listen to for an extended period),
Cowboy Junkies ‘Sweet Jane’ (a bit restrained, but these aren't a 'big, boxy' speaker so that would be expected’),
Don Williams' DDD version of 'Country Boy' (benefited from a bit of 2k bump on an EQ),
Nickel Creeks’ “When in Rome” from their CD "Why Must the Fire Die?" (Again, as with the Allison Kraus material, Fretted instruments ALL very pleasing to listen to for an extended period),
and a few others, all digitally recorded and some 'DDD'.
Decent power handling characteristics for a speaker this size, but with our 500 Watt Hafler, we didn't push them much past about 10:30. Great balance, detailed sound reproduction and I experienced essentially NO LISTENER FATIGUE!!!
Fabulous 'all around' speaker for vintage or modern stereo systems, especially where you need more of a 'tower' speaker.

PSB 1000 Features:
- *2.5 Way Design (means that the lower woofer serves as a sort of 'subwoofer' handling the bass range up to a few hundred Hertz. The upper woofer covers the full range of the balance of the bass and is then filtered (crossed over) at 2.1kHz)
- 2x 6.5" Poly-coated, Foam surrounded Woofer with great condition foam surrounds
- 1" Ferrofluid Cooled, Blended Cloth, Dome Tweeter
- "Real" internal cross-over (not just a "couple of capacitors in line")
- 4 Ω nominal rating
- 2.5" Tuned port for extending bass response
- Quad Binding Post speaker connectors can be simply ran full range leaving the 24k Gold plated shunting strap in place, or if you so desire, the straps can be removed and they may be "Bi-Amped"

PSB 1000 Specifications /Specs:
Frequency Response: 45-20,000Hz ± 3dB (low freq cutoff -10dB @ 29Hz)
Efficiency: 92 dB 1w @ 1m
Crossover point: 500Hz / 2.1kHz
 Nominal Impedance: 4Ω each
Recommended Minimum / Maximum Power amplifier rating: 15 / 150 Watts
  
These are great sounding speakers. Again, our speaker tech has completely refurbished, tested and Certified these speakers performing the previously mentioned processes. Again, these are more "detail" oriented speakers not "Power Pounding, Party" speakers (yes they get loud, but that's not their "forte"). If that's what you're looking for then don't buy these. Great speaker for small-medium to medium large systems, at most volumes including filling most rooms.
Each measures 37.75" h (about 'hip' high) x 9" w x  12.75" d and weighs 40 lbs unpacked. Includes our 30 day warranty (excluding problems due to under / over powering)

CERWIN VEGA SPEAKERS
CERWIN VEGA DX-7 DX7 STEREO SPEAKERS
Radial 'horn' tweeter
& Fresh, New and Correct foam suspension on the woofer
Made in USA
 Circa mid 1980-84
for sale
BIG and BIG sounding Cerwin Vega "HED", DX7, 3-way speakers! They are capable of high volume levels while producing "pounding" & "tight" bass with great balance on the top and mid end. Great balance too.
Our speaker tech has completely gone through and 'Certified' these. Both woofers have NEW, fresh foam surrounds (YES, 'properly', using voice coil shim method!!! evidenced by the acetone stain ring on the woofer cone emanating from the dust cap). All drivers were removed and tested individually. Since the woofers just had new surrounds installed, they should be good for many years.
The original / OEM fuse 'pop out' fuse holders still intact and holding fine on this pair. Cosmetically, they're in decent shape. There's a few minor edge dings, (mostly to the rear edges) (see above photos). The grills were cleaned & the wood grain, vinyl wrapped cabinets in great shape, again with only a few minor nics / scuffs. The grill fames and locate pins all in good shape with no breaks or missing pins. Overall the original, black knit in good shape.
Next, as always they were tested with 20-20k White Noise, swept them with our AF generator from 1Hz-5kHz to find any any extraneous vibration or acoustic anomalies.
Then came our standard, 'issue exposing' and on some levels, 'abusive' test recordings. These speakers are ready to go!
 We auditioned this pair extensively and 'THEY DELIVERED' as expected, but additionally adding the 'gasketing' really 'tightened' up the cabinets and cleaned up the bass response.

Our demo cuts included the following; Dire Straits' "So Far Away" from their album 'Brothers in Arms' album,
Donald Fagens, "I.G.Y." from the album "Night Fly" (solid and snappy reproduction), '24K Gold Edition of Jennifer Waren's "Famous Blue Raincoat' (the saxophone was bright and smooth),
TLC's "Scrub" from their album 'Fan Mail' (did 'sub-bass' note @ 1'25" & 1'35" VERY WELL),
Allison Kraus and Union Station's "Baby, Now That I've Found You" (I expected this to be 'beamy' in the mids, but was upfront and natural),
Cowboy Junkies ‘Sweet Jane’ (nice and open’),
Don Williams' DDD version of 'Country Boy' (good, ‘up-front’ in the soundstage),
Calvin Hampton's, "The Wedding March" from "Digital Pipes, The Splendor of the Organ", a digital recording of a cathedral pipe organ (HUGE!),
Trapt’s “Headstrong” (was ‘solid’ and the woofers exhibited no sign of fatigue even at upper power levels)
Most of the cuts from Michael Jacksons' 'Number Ones' such as "Bad" "Beat It", and "Smooth Criminal", were ‘strongly’ reproduced,
Van Halens' cut "Drop Dead Legs" from the CD "1984" ROCKED!

Nickel Creeks’ “When in Rome” from their CD "Why Must the Fire Die?" (was 'open and up-front'),
and a few others, all digitally recorded and some 'DDD'.
 Incredible power handling characteristics for a speaker this size. They are able to handle "power" better MUCH than your average speaker. Not simply referring to their wattage rating, but just the way they perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler 500 watt power amplifier. 'Solid', punchy and 'tight' low-end, with no 'mush'. Great balance, detailed sound reproduction and very little LISTENER FATIGUE!!!
Fabulous 'all around' speaker for vintage or modern stereo systems.

Cerwin Vega DX-7 Features:
- 12" Foam surrounded Woofer with fresh foam surrounds just installed for years of trouble-free service

TANNOY NEAR FIELD STUDIO MONITORS / STEREO SPEAKERS
TANNOY SYSTEM-6 NFM-II
 #...1260M / #...1261M
Made in Scotland
Circa 1994
for sale

"Of all loudspeaker manufacturers in the world Tannoy has the greatest number of loudspeakers in use for sound production in british and European studios. An enormous number of successful recordings have been produced on Tannoy Monitoring since the first introduction of the Tannoy Dual Concentric loudspeaker in the 1950s."..."INCLUDING, Pink Floyds, "Dark Side of the Moon"!"
Our speaker tech has completely gone through and 'Certified' these. Woofers feature Butyl rubber surrounds which don't deteriorate like foam does. We pulled the drivers to make sure they were damped internally with poly-spun batting and had flange gaskets, and simply to make sure all was 'in order' internally, and it was. Once re-assembled, we completely tested them with WN 20-20k and swept them with our AF generator from 20-5,000 Hz feeding them with the output from our Hafler 500 Pro Power Amp, looking for any vibrations or other anomalies (and there were originally a few that we addressed, as there typically are on speakers). Then further auditioned with a myriad of our difficult to reproduce 'test' CD's.
These are 'Studio Recording Monitors' so are going to have a very 'flat' response, and won't be colored like most 'home audio' speakers. I sold Yamaha NS-10M's throughout the 1980's and 90's and these essentially sound very similar to those. If you're going to use 'studio monitors' as your 'everyday listening speakers' most folks will likely feel the need for an EQ (which I use most of the time regardless of the particular speaker I'm listening to).
Here are links to two very informative pages regarding these Tannoy speakers;

https://stereonomono.blogspot.com/2014/03/tannoy-nft-and-dmt-series-ii.html

Great sounding speaker for detail, 'flat' response and balance.
 Features include:
 
- 2-way, Concentric Driver, Bass-Reflex design
- HEAVY DUTY, 6.5", 1667 Dual Concentric, polypropylene Low Frequency Driver (woofer) with nitrile / butyl rubber, high-compliance surrounds
-.75" Concentrically located, horn Tweeter
- 30mm tuned port for extended low end
- Bi-Wire-able / Bi-amp-able via Gold, Multi-Way Binding Posts (Original Tannoy Shorting apparatus included)
- "Real" and heavy duty internal crossover.
 
TANNOY SYSTEM-6 NFM-II Specs:
Efficiency: 91 dB 1W@ 1m
Frequency Response:  52Hz- 25kHz ±3dB
Crossover points: 2,000Hz
Dispersion: 90° Conical
Cabinet volume: 10 litres
Nominal Impedance: 8Ω each
Recommended Power amplifier rating: 20-150 Watts

Great performing, near-field, studio / mix monitor.
Cosmetically they're in near new condition. Other than some very light 'scuff marks' on the cabinet tops (primarily because the finish is 'flat and textured' - see photos above) there's isn't really anything to speak of. Cabinet and grills all in great condition. Grill frames perfect with no broken or repaired parts and are stain free. Cabinets measure 13.75" H x 9.25" W x 9.25"D and weigh 13 lbs each. Includes our standard 30 day limited warranty (excluding problems due to under / over powering).

PARADIGM STEREO SPEAKERS
PARADIGM 7SE MK-III HOME AUDIO SPEAKERS
#...7156-7157
Made in Canada
Circa 1993-97
 for sale
The following is my impression after extensively auditioning the Paradigm 7SE MKIII's. These speakers are much more forgiving one placement than their larger brothers, the 11SE MKIII. I found that almost regardless of placement or proximity to one another, their performance sonics came across as natural, with great balance and detail, with very little limiting effects on each other.
These are especially great speakers if you are a fan of 'modern' Jazz or 'Brass' / 'horn sections' and vocally strong selections. Also great for folk rock and easy rock.  If you're a 'rocker', or need 'tunes for your parties' these are NOT the speakers for you. If you appreciate very 'natural' reproduction, especially of 'brass-horns, pianos, jazz drums and percussion, then these speakers will be marvelous!

PARADIGM 7SE MKIII FEATURES INCLUDE:

- 2-way, 3-Driver, Bass Reflex, vented via a 'Quasi-3rd Order, Resistive' port for Impressive Low-End Performance (and their 'Low-End' is VERY impressive)
- Dual 165mm / 6.5" Low Frequency Drivers (woofers), Non-deteriorating, Butyl Rubber surrounds, with die-cast alloy frames, Polypropylene cones & 1.5" VC's.
- 25mm / 1" Treated Textile Dome Tweeter with aluminum VC former that's 'ferro-fluid' cooled and damped
- Internally braced cabinets to reduce unwanted resonances and 'ballooning' effects
- 3" High-Velocity, Tuned bass port
- Bi-Wire-able / Bi-amp-able via Gold, 5-Way Binding Posts

PARADIGM 7SE MKIII ORIGINAL SPECIFICATIONS / SPECS:

System design: 2-Way, 3-Driver Bass Reflex, vented via a 'Quasi-3rd Order, Resistive' port for Impressive Low-End Performance
Frequency Response: 50-20,000Hz ± 2dB w/ a 'Low End' you can definitely feel (as in 'shakes the concrete floor in our audition space)
Nominal / Minimum Impedance: 6/4Ω
Sensitivity; Room / Anechoic: 92dB / 89dB 1W@ 1m
Cross-over type / frequencies: Quasi-Butterworth @1.8kHz
Recommended Power amplifier rating: 15 to 175 WPC (I would not consider utilizing these speakers with less than something rated at least 40 Watts of 'Old School' type power)
Max Power rating: 120 Watts of 'Music Power'

From the original Paradigm 7SE MKIII / MK3 brochure, "This elegant design occupies very little floor space and yet offers stunning performance - very lo coloration with wide bandwidth, low distortion and high power handing...
Advance drive units and a sophisticated dividing network ensures excellent clarity and imaging. Twin bass / mid drivers provide high dynamic power ability...
The 7seMk3 exemplifies the idea that strict adherence to the principles of simplicity and finesse in design will result in a product whose performance is second to none at a price with which none can compete".

The tall 'tower' stature of the Paradigm 7seMk3 speakers puts the tweeter more on plane with your ears, instead of your knees.
Our speaker tech has completely gone through and 'Certified' these. He completely tested them with both recorded material, W/N @ 20-20k and swept them with our AF generator from 10Hz-25,000 Hz and feeding them with the output from our Hafler DH-500 Pro Power Amp, looking for any irregular vibrations / anomalies in either the drivers. driver mounting, crossovers or cabinet structure integrity. We then further auditioned with a myriad of our difficult to reproduce 'test' CD's. They performed and sounded great!
I spent an inordinate amount of time auditioning these speakers. I tried about every genre of music, including most of the selections listed on our 'Demo Cuts' page but here are some notes I made on their post restoration 'check sheet'; TLC's "Scrub" from their album 'Fan Mail', did 'sub-bass' note @ 1'25" & 1'35" SO SOLIDLY & PROMINENTLY THAT IT SHOOK OUR CONCRETE FLOOR (and that is a 'tell tale' indicator of how most of the rest of the testing would go, and was essentially the same 'low-end' performance we experienced with the largest of this series, the '11se MkIII'), Dire Straits' "So Far Away" from their album 'Brothers in Arms', Donald Fagens, "I.G.Y." from the album "Night Fly" "Was as near perfect as any speaker could do. Good power and 'snap', great balance, and fine WITHOUT an EQ!", '24K Gold Edition of Jennifer Waren's "Famous Blue Raincoat' allowed her vocals to sound as though she was in the room with me on a 'live sound system',  Allison Kraus and Union Station's Baby, Now That I've Found You" '"was very natural and open. These speakers were also able to separate the bass guitar, acoustic guitar and here vocals VERY well", Don Williams' DDD version of 'Country Boy' 'Was VERY LIVE', Trapt's 'Headstrong', Most of Van Halen’s “1984” and Michael Jackson’s “BAD” all sounded great, but have a limit at about 116dB / 1m. Beyond that you’ll get ‘woofer snap’ (by the way, 116dB is pretty damn loud). Calvin Hampton's, "The Wedding March" from "Digital Pipes, The Splendor of the Organ" a digital recording of a cathedral pipe organ, was "BIG AND OPEN" without any external processing, and a few others, all digitally recorded and some 'DDD'.
Decent power handling characteristics. They are able to handle "power" better than your average speaker. Not simply referring to their wattage rating, but just the way they perform at higher power / volume levels without "falling apart" sonically (at least up to about 116dB with some fairly 'strenuous' material). We 'stood' on them to a reasonable degree with our test Hafler 485 Watt power amp.

The Black Oak, 'wood grained', satin finish cabinets in good shape as are the grills and grill frames. Only cosmetic issues to speak of would be a repaired 'ding' on the rear edge of one cabinet, minor grill cloth snags and some minor 'dimpling' in one of the tweeter domes (cosmetics only).
Great speaker for up to mid-high volume levels. Again, these are more "detail" oriented speakers NOT "Power Pounding Party" speakers. If that's what you're looking for then don't buy these.
Great for most Jazz, and percussive jazz, brass / horn section, 'punch, well mixed modern music (think 'YAZ'), 'percussion heavy' selections / music. Very accurate, detailed & 'refined' sound! Comes with an e-copy / pdf of the original Paradigm 7SE MKIII / SE series brochure. Cabinets measure 35" H x 8.25" W x 14.75" D and weigh a 39lbs each. Includes our standard 30 day limited warranty (excluding problems due to under / over powering).

"Just a note of thanks after all of these years. On August 31, 2012 I purchased a pair of Sansui SP-3000 speakers from you. I matched them with a set of Pioneer HPM-100 speakers. All speakers are driven by a Marantz 2275 receiver. I have a Marantz 6200 turntable and Sony TC-280 reel to reel tape deck. The Sansui speakers are tremendous for acoustic guitars and horns. The base comes from the Pioneers. Together, what a sound. I never get tired of listening to the music, old soul, early 70’s rock bands. My favorite of course is the Rolling Stones. Thanks again for the tremendous Sansui speakers. I highly recommend them. PS: they have never been worked on since I bought them in 2012. I just wanted you to know what a great company you have. Rock On!", Mike in Ohio

VINTAGE EPI STEREO SPEAKERS
EPICURE / EPI 'STAT 450'
w/ ELECTROSTATIC TWEETERS
#...0952 / 0966
Circa 1986
Made in USA
for sale
These speakers are all about 'IMAGING'.
One of the rarer of the Epicure speaker models. The Epicure Stat 450 stereo speakers with 'electro-static' tweeters. If you are a 'modern' Jazz fan and can afford to have a designated 'sweet spot' listening area, then you would love these speakers. Fabulous imaging. Also great for folk rock and easy rock. If you're a serious 'rocker', need 'tunes for your parties' or want speakers to 'passively' listen to, then these are NOT the speakers for you. If you appreciate very 'natural' reproduction of vocals, horns (especially sax and clarinet), pianos, jazz drums and percussion, then these speakers will be mesmerizing!
Again, these speakers are only effective 'on-axis' with the listening area in the 'sweet spot' (if you're not sure what that means, give me a call).

EPICURE / EPI 'STAT 450' FEATURES INCLUDE:

- 2-way, Acoustic Suspension
-10" Low Frequency Driver (woofer) w/ resonance reducing back coating. Fresh foam surrounds just installed for trouble-free service
- 5"x12" Triple panel, True Electrostatic Tweeter
- AC Tweeter power adaptors included

EPICURE / EPI 'STAT 450' ORIGINAL SPECIFICATIONS / SPECS:

Frequency Response: 44-20,000Hz +- 3dB
Nominal Impedance: 4Ω
Cross-over frequencies: at 1kHz
Recommended Power amplifier rating: 20-250 Watts

While these speakers are physically large, it is not without reason. Their expansive baffle board serves to reduce any "out of phase" reflections / wave anomalies from neighboring surfaces. This way the speaker can "control" it's sonic results, instead of having it's environment as the major contributor. Secondly the tall stature of the EPI STAT 450 speakers puts the tweeter more on plane with your ears, instead of your knees.

Unfortunately these are both missing their grills. The locating / attachment pins are intact, but no grills. With the exception of some normal scuffing to the tops and a few minor 'battle scars', the wood grain, vinyl wrapped cabinets are in good shape. Some wear to the built-in bases (see above photos). Our speaker tech has completely gone through and 'Certified' these.  Both woofer surrounds just replaced with new foam for trouble-free service. We also did multiple internal wiring repairs, replaced one of the speaker wire / AC power input panels, added foam to rear of tweeter plate mounting flanges to isolate from the cabinet (should have been done at the factory originally on this model) and added isolation material to the woofer mounting flanges. Following that work and mod's, we completely tested them with both recorded material, W/N 20-20k and swept them with our AF generator from 20-5,000 Hz and feeding them with the output from our Hafler P-225 Pro Power Amp, looking for any vibrations or other anomalies (and there were originally a few that we addressed, as there typically are on speakers). Then further auditioned with a myriad of our difficult to reproduce 'test' CD's.
Great speaker for up to mid volume levels. Again, these are more "detail" oriented speakers NOT "Power Pounding Party" speakers. If that's what you're looking for then don't buy these. These are true to the classic New England speaker sound. Again as we mentioned earlier, placement of speakers / listener, while most times is important, is imperative with these speakers. If you can afford the space to arrange yourself, in correct proximity to these (between 1 to 2 x d, call me for clarification) you'll be amazed with the 'presence' of these speakers. Great for most Jazz, acapella vocals, acoustic guitar recordings, blue-grass, gypsy jazz & classical / symphonic / string music. Very accurate, detailed & 'refined' sound! Includes AC power adaptors. Cabinets measure 37.5" H x 17.5" W x 10.5" D  and weighs a hefty 50 lbs each. Includes our standard 30 day limited warranty (excluding problems due to under / over powering.

AUDIO EQUALIZERS
and our philosophy on them.

"Are Equalizers really necessary? I just paid $THIRTY GRAND$ for my speakers. They shouldn't need any EQ. Right!??"

Short answer is quite probably, maybe..."YES", as an EQ will generally be beneficial to many, if not 'most', audio systems.
     Most speaker designers strive to make a speaker's curve as "flat"* as their projected size parameters and target retail price will allow. The human hearing curve is not "flat". Most folks' hearing is accentuated in the midrange (it's where the human voice is centered) and attenuated in the bass and treble. Sort of a reverse "rock-n-roll smile" curve. When you hear a good, "flat" response speaker, it will likely appear to have, at least for most listeners, an over abundance of mids. It likely will also have a deficiency in bass and possibly treble. It will most likely sound  "thin", the degree of which can vary from slight to extreme, depending, on many variables. This might not even be readily apparent when auditioning speakers, but generally if you hear a pair speakers with an appropriately adjusted, EQ engaged, then you listen to it bypassed, you will probably want to re-engage it as quickly as possible.
     The classic arguments against using an EQ have been that an EQ, or any additional inserted signal processing device, makes the signal path less "pure" and adds noise. Also, again, "these speakers were expensive and shouldn't need an EQ". To address the first point, this issue can usually be reduced to a more than desirable point by utilizing a high quality EQ or signal processor. The noise floor should certainly be below audible levels, and it doesn't take too much of an EQ to achieve that for most folks systems.  While the first point is valid, a good EQ's benefits usually far outweigh any minor noise issues, which are probably below most listeners audible limits in the first place. The second issue was answered previously, in the above paragraph.   In fact, the better the speakers, the more they would likely benefit from a reduction of the midrange frequencies, due to their as "flat as possible" curve. Again, this would apply to the average persons hearing curve. Some "cheap" speakers, will have a "rock-n-roll smile" EQ curve built-in by utilizing drivers, crossover and cabinet combinations, that have an over abundance of bass and treble, and a deficit of mids by design. That would beg the question of "why wouldn't they all just do that then". The answer to that is that any respectable speaker manufacturer wouldn't try and dictate a built-in curve into a speaker other than as flat as assigned parameters will allow, for a number of reasons.
     Another less apparent, but still valid reason for utilizing an EQ can be to compensate for listening room acoustic characteristics. This is generally more difficult to assess, but overtime could become a desired need. This need would obviously change with any parameter change in the listening environment. Also, and no offense, but as we age and as we are exposed to various, sometimes, injurious sonic environments and events, our sensitivity to frequency ranges will change.
     One way to look at a specific speaker / listening environment combination is to think of it as a blank artists canvas. A really high quality speaker system would be comparable to a high quality canvas, brushes and material. Said another way, a "non-flat" EQ curve / listening environment / speaker combination is akin to starting your painting with a dirty, blotchy canvas. The listening environment to a well lit room with natural lighting, conducive to a creative mood. Until you "shape" the EQ, there is no painting on the blank canvas. Once you shape the EQ to your tastes, in a way that compliments the speaker design / room combination, you have created your work of art.

    While I can appreciate all the arguments for not using an EQ, in the end, I generally use an EQ with it's curve slightly boosted in the bass and treble frequencies and attenuated through the mid frequencies from "Zero" position (the "rock-n-roll smile" curve). It will usually require adjustment following any change in speakers, listening environment parameter adjustments and with the material I am listening too. I also have a 1/3 octave RTA monitor / spectrum analyzer with a pink noise generator and analyzing mic to establish an accurate "flat" point to start from.

 * Contrary to a somewhat common misconception, "Flat" does not mean "dull". "Flat" refers to the graphic "curve" of a speakers output when analyzed by a spectrum analyzer. Ideally a speaker should be able to reproduce the human hearing range with all frequencies as close to "zero" (even amplitude or "flat") as is practical for the intended design / price point levels. The listener can then modify it from there by various methods (usually some sort of signal processor such as an EQ) to their tastes.

Our speaker tech has completely gone through and 'Certified' these.  Both woofer surrounds just replaced with new foam for trouble-free service  (YES, 'properly', using voice coil shim method!!!). During the AF generator sweep, we found loose base ports (didn't 'feel' loose, but our AF generator found them). That was addressed (was probably like that from the factory). Following that work and mod's, we completely tested them with both recorded material, W/N 20-20k and swept them with our AF generator from 20-5,000 Hz and feeding them with the output from our Hafler 500 Pro Power Amp, looking for any vibrations or other anomalies (and there were originally a few that we addressed, as there typically are on speakers). Then further auditioned with a myriad of our difficult to reproduce 'test' CD's.
Great speaker for up to mid volume levels.

Great sounding speaker for detail, balance and presence. Handles power quite well.
 Features include:
 
- 3-way, Bass-Reflex design
- 8", Ribbed, coated pulp, Low Frequency Drivers (woofer) with new foam
-5" coated pulp Midrange with accordion, cloth surround
-1" Pure Titanium Dome Tweeter
- 2.75" tuned port for extended low end
- Foam covered baffle board to reduce mini reflections
- "Real" internal crossover. Actually it's a fairly serious crossover. VERY well designed and built.
 
JBL LX44 Specs:
Efficiency: 91 dB 1W@ 1m
Frequency Response:  45Hz- 20kHz ±3dB
Crossover points: 800Hz & 4,000Hz
Nominal Impedance: 8Ω each
Recommended Power amplifier rating: 10-150 Watts

 Again, both woofer surrounds freshly replaced for trouble-free service. Great speaker for up to fairly moderate volume levels. These are "detail" oriented speakers that can also get loud and fill a room. Great for about any type of music. We tested them extensively and have temporarily added them to our audition line-up because we were so impressed. If you've read some of our other 'audition notes', you'll know what is meant when I say that these speakers, "reproduced the "TLC 'Sub-Bass' note' VERY well" when situated on the floor. If you're looking for "true" wide frequency response, balance and detail and a speaker that can handle power well too, then these may be the speaker for you. They ROCK!!! This would be a great speaker for a room with limited  space, but you need to get loud as the cabinet has a lot of cubic volume, but with a small "foot print". 
Cosmetically they're in near new condition. Not really anything to speak of. Cabinet edges and corners crisp and practically nick free. Wood grain, vinyl wrap looks great! One grill has a small, 'pea sized' snag-hole in the upper right corner . Grill frames perfect with no broken or repaired parts and are stain free. Cabinets measure 23" H x 11.75" W x 12"D and weigh 29 lbs each. Includes our standard 30 day limited warranty (excluding problems due to under / over powering).

 Circa ~1999
for sale
 We aren't typically very interested in A/V speakers, but these Yamaha YST-A755's can hold their own in our 2-channel system. This speaker is large enough, that even though it is a modern, A/V cabinet, it sounds great on an "old skool", 2-channel amp!  Great speaker for detail, balance and that big "wall-o-sound" presence. Handles power VERY WELL!
We have completely tested them with both recorded material, W/N 20-20k and swept them with our AF generator.
 Features include:
 
- 2-way, Bass-Reflex design
- 8", Polypropylene, Low Frequency Drivers (woofer)
 -1" Soft Dome, coated cloth Tweeter
- 2.25" tuned port for extended low end
- "Real" internal crossover (not just a cap on the tweeters)
- All original Yamaha made drivers
 
Specs:
Efficiency: ~88-89 dB 1W@ 1m

Recommended Minimum Power amplifier rating: 10 Watts
Max power rating: 160 Watts
 
 While these speakers are not our typical fare, they are great sounding 2-channel speakers (yes, of course they would sound great in a theater / surround system) By nature, the "tall" stature of the Yamaha YST-A755 puts the tweeter more on plane with your ears, instead of your knees.
 
These are some what "cosmetically challenged" up close, but nothing too distracting. One of the cabinets had some wall mounting brackets bolted in to it so it has a few small holes and both speakers have a few minor scuffs to the satin black, wood grain finish. The original black knit grills are in good shape with a few very minor snags and one is missing the "Yamaha" logo (see far right photos above. The photos were taken at close range with a flash and make the blemishes look very much more noticeable then they are in reality). Grill frames perfect with no broken or repaired parts.

 Again, both woofer surrounds freshly replaced for  years of trouble-free service. Great speaker for up to fairly high volume levels.

#...0209 / 0210 (consecutive numbers)
Circa 1993
Made in the USA (yes, really)
for sale
Great performing and sounding Yamaha NS-A635A 3-way speakers have a room filling, "tight" sound that ensures sonic accuracy. Great for home use or project studio monitors. If you can't afford the famous Yamaha NS-10's (now, currently north of $1000.00), then these may be an affordable alternative for your project recording studio (I was a dealer for NS-10's back in the 90's and have heard and sold many).


Our speaker tech has completely gone through and 'Certified' these.
We have completely tested them with both recorded material, W/N 10-20k and swept them with our AF generator. Prior to testing with the sweep generator, we added gasket material under the tweeter flanges in each cabinet to eliminate resonate vibrations. This is really a 'finishing touch' on this model of Yamaha's that should have been done at the factory, but is rarely done by most companies / manufacturers. Midrange and woofer cone edges and surround attachment surfaces inspected for any separation, fatigue etc. We also proactively glued any cracks in the plastic tweeter flanges (most all driver flanges / mounting plates on vintage speakers will have holes emanating from the screw holes). We also added 'poly-spun' batting to the cabinet space to further tighten up the low-end, eliminate hollowness / cabinet ringing. Again, should have been done at the factory, instead of relying an 'empty cab' to allow 'boomy bass' which on the original sales floor, made the box appear sonically 'larger' than it is by making the box seem to be producing more bass. The 'bass' that an un-damped cabinet produces is 'hollow and flappy', and not what you'll want to listen to over the long haul. That would be come very fatiguing soon.
Handles power decently and reproduced the low-end in our most difficult test CD! If you've read some of our other 'audition notes', you'll know what is meant when I say that these speakers, "reproduced the "TLC 'Sub-Bass' note' VERY well" when situated on the floor.

 Yamaha NS-A635A Features include:
   
- 3-Way, Acoustic Suspension design for studio monitoring "tight bass"
- 8” High-Compliance, Cloth Surround, Polypropylene Coated, Long-Throw woofer, woofer w/ non-deteriorating cloth surround
- 4” mid non-deteriorating paper surround

 #...5369
 CIRCA 1993
  for sale
  Here's a GREAT 'looking' pair of Infinity RS-225's (and looks are all these have going for them).

These feature 'Gutless' / 'Flappy' bass with anemic power handling capability, and are quite likely one of the 'all around' WORST sounding speakers I have auditioned in the past 40+ years!

Having said that, if you need a pair to replace a pair your friend owns that were destroyed when you threw a surprise 'house party' at his place, or you're a moving company and destroyed your client's pair and need to replace them, or you sold yours' to buy drugs (if you listened to these prior to purchase in the first place and STILL purchased them, you were probably on drugs), then here you go. These speakers are for you. (no, I'm not 'anti'-Infinity! Quite the opposite. I personally own many classic models including an original pair of RS-IIIb's that I love. Also, no, I'm not being unduly unfair by expecting 'so much' from a smaller speaker design. I've had countless 'small' speakers in the past that sounded great and were light years superior to these on most counts.)
  Features include:
  
- 2-way Acoustic Suspension design
- 6.5" Polypropylene Cone Woofer w/ fresh new foam surround (very difficult to do on this series as the dust cover is hard to remove to shim the VC, but must be done)
- .5" Ferrofluid cooled, polycarbonate tweeter
  
 Specifications:
 
Speaker Cabinet Design: 2-way, Acoustic Suspension
Driver Complement: One 6.5-inch, Polypropylene woofer, and one .5" Polycarbonate tweeter
Frequency Response: 70-20,000Hz +- 3dB
Efficiency: 90dB 1W@ 1m
Nominal Impedance: 8Ω nominal
Cross-over frequencies: 3kHz
Recommended Power amplifier rating: 10-75 Watts minimum (good luck with anything much over 20 or 30 Watts that contains any bass / low-frequency)

 These are great little 4 ohm speakers designed for indoor, outdoor or auto use (works great with car stereos since they are 4 ohms). Also great with portable systems that need 4 ohm speakers to realize the full power potential of the amplifier. The case is made of the same material that is used to make their 'pro audio' speakers such as the famous 402's and 802's (I've had a pair of 802-II's for over 30 years for a PA system). Technically it's: "Mica-reinforced, Polyethylene Copolymer structural foam" (that's useful info if it ever comes up while playing Trivial Pursuit). I think it's the same as Zytel nylon similar to many outdoor PA speakers are made from and also what Yakima car roof racks are made from. Very strong & durable with the added benefit of being noise free when used as an enclosure. These use the same size / design driver found in the famous and classic 901 speaker.

STEREO / CENTER CHANNEL SPEAKER
Made in USA
for sale
Great little 8 ohm speakers designed for the center channel of A/V, Home theater systems and for indoor, outdoor or auto use (works great with car stereos since they are 8 ohms). Magnetically shielded for use in close proximity to video monitors. Also great with portable systems that need 8 ohm speakers to realize their full power potential. The case is made of the same material that is used to make their 'pro audio' speakers such as the famous 402's and 802's (I've had a pair of 80's for over 30 years for a PA system). Technically it's: "Mica-reinforced, Polyethylene Copolymer structural foam" (that's useful info if it ever comes up while playing Trivial Pursuit). I think it's the same as Zytel nylon similar to many outdoor PA speakers are made from and also what Yakima car roof racks are made from. Very strong & durable with the added benefit of being noise free when used as an enclosure. These use the same size / design driver found in the famous and classic 901 speaker (different impedance. Also a very durable and time-tested unit. Each cabinet also features 2 recessed "T-nuts" for mounting  to optional brackets (not included). Cloth covered grill in great shape. The cabinet is also in perfect condition with no chips or cracks. Speaker test and sound great! Power Rating: 10 to 100 Watts max (constant rating of 60 Watts) & 8 Ohms. Speaker measures 9" W X 6" H

AUDIO EQUALIZERS
and our philosophy on them.
   
                               "Are Equalizers really necessary? I just paid $30 grand for my speakers. They shouldn't need any EQ. Right!??"

Short answer is probably yes, an EQ will generally be beneficial to most systems.
     Most speaker designers strive to make a speaker's curve as "flat"* as their projected size parameters and target retail price will allow. The human hearing curve is not "flat". Most folks' hearing is accentuated in the midrange (it's where the human voice is centered) and attenuated in the bass and treble. Sort of a reverse "rock-n-roll smile" curve. When you hear a good, "flat" response speaker, it will likely appear to have an over abundance of mids, at least for most listeners. It will also likely have a deficiency in bass and possibly treble. It will most likely sound  "thin", the degree of which can vary from slight to extreme, depending again, on many variables. This might not even be readily apparent when auditioning speakers, but generally if you hear a pair speakers with an appropriately adjusted, EQ engaged, then you listen to it bypassed, you will want to re-engage it as quickly as possible.
     The classic arguments against using an EQ have been that an EQ, or any additional inserted signal processing device, makes the signal path less "pure" and adds noise. Also, again, "these speakers were expensive and shouldn't need an EQ". To address the first point, this issue can usually be reduced to a more than desirable point by utilizing a high quality EQ or signal processor. The noise floor should certainly be below audible levels, and it doesn't take too much of an EQ to achieve that for most folks systems.  While the first point is valid, a good EQ's benefits usually far outweigh any minor noise issues, which are probably below most listeners audible limits in the first place. The second issue was answered previously, in the above paragraph.   In fact, the better the speakers, the more they would likely benefit from a reduction of the midrange frequencies, due to their as "flat as possible" curve. Again, this would apply to the average persons hearing curve. Some "cheap" speakers, will have a "rock-n-roll smile" EQ curve built-in by utilizing drivers, crossover and cabinet combinations, that have an over abundance of bass and treble, and a deficit of mids by design. That would beg the question of "why wouldn't they all just do that then". The answer to that is that any respectable speaker manufacturer wouldn't try and dictate a built-in curve into a speaker other than as flat as assigned parameters will allow, for a number of reasons.
     Another less apparent, but still valid reason for utilizing an EQ can be to compensate for listening room acoustic characteristics. This is generally more difficult to assess, but overtime could become a desired need. This need would obviously change with any parameter change in the listening environment. Also, and no offense, but as we age and as we are exposed to various, sometimes, injurious sonic environments and events, our sensitivity to frequency ranges will change.
     One way to look at a specific speaker / listening environment combination is to think of it as a blank artists canvas. A really high quality speaker system would be comparable to a high quality canvas, brushes and material. Said another way, a "non-flat" EQ curve / listening environment / speaker combination is akin to starting your painting with a dirty, blotchy canvas. The listening environment to a well lit room with natural lighting, conducive to a creative mood. Until you "shape" the EQ, there is no painting on the blank canvas. Once you shape the EQ to your tastes, in a way that compliments the speaker design / room combination, you have created your work of art.

    While I can appreciate all the arguments for not using an EQ, in the end, I generally use an EQ with it's curve slightly boosted in the bass and treble frequencies and attenuated through the mid frequencies from "Zero" position (the "rock-n-roll smile" curve). It will usually require adjustment following any change in speakers, listening environment parameter adjustments and with the material I am listening too. I also have a 1/3 octave RTA monitor / spectrum analyzer with a pink noise generator and analyzing mic to establish an accurate "flat" point to start from.

 * Contrary to a somewhat common misconception, "Flat" does not mean "dull". "Flat" refers to the graphic "curve" of a speakers output when analyzed by a spectrum analyzer. Ideally a speaker should be able to reproduce the human hearing range with all frequencies as close to "zero" (even amplitude or "flat") as is practical for the intended design / price point levels. The listener can then modify it from there by various methods (usually some sort of signal processor such as an EQ) to their tastes.


 

Jerry of OakTreeVintage the 'Wall-O-Sansui'
Sansui Lattice Grill Speaker models SP-200, SP-2000, SP-2500, SP-3500, SP-5500
 from Late 1960's thru 1970's topped with a Sansui G-7700
(No, that receiver couldn't power that kind of speaker load, it was just to hold them down incase the wind kicked up)

 

We get a number of requests for a 'Wall-O-Speakers' for trade shows, photo back grounds, room decoration for restaurants, bars, micro-brews, music rooms, movie / video props etc.
Most folks inquiring about installations such as this erroneously think that something like this is just 'a bunch of old speakers' that are probably $5-$20 each. I suppose you could (given enough months / years) purchase enough 'low-end' speakers from such places as thrift stores for that kind of money, but to do something like this in a 'timely manner', utilizing 'respected' brands / models is not an easy endeavor. Collecting this amount of speakers typically takes years. Some of these we've had for a couple decades. Once I explain the above to most perspective buyers, I am usually help them realize it's not something that is going to happen for a 'few hundred dollars' (the shipping alone would be $2000 to $3000 to many 'domestic USA' locations {and certainly more for 'non-USA' locations}). Regardless, for those that realize what's 'really involved' in building an installation like this, we are offering the following. It's been made more affordable as we happened to have a number of speakers that were either slated for parts, or we had not done any of our restoration work to. A few may have 'changed parts' or unknown issues, but many could actually be either tested 'as working' or with the proper attention, made to function. Brands included Akai, AR-16, Avid Model 100, B&W, Bose 901, EV-Four, Fisher XP-9b, Fostex Studio Monitors, Heathkit TS-1630, Infinity CS-3000, JVC, Kenwood, Klipsch Heresy, Knight, Little Lemons, Mission 717 & 770, Pioneer CS-77's, Realistic Miniums-7 & Nova-7b, Wharfedale 70d and a few others.
The two yard sticks in the lower, center of the photo should give you a visual idea of the size. Technically it measures 90" (7.5') wide x 94" (7.8') high and has a max depth of 15" (Wharfedale 70d's). (There are a few 'blocks of wood' shimming up cabinet ends where speakers wouldn't "Tetras Perfect" fit.)
$6999. each wall (two walls available)
(Plan on 20-40% (possibly more in the current 'mad times' we're in) additionally for shipping to most 'domestic / USA' locations)

           

Further details available by contacting us at 800-806-4231 ext 2 or emailing to " sales@oaktreevintage.com ".
We actually have it also available as a 'mirror imaged' wall making a 'corner, or simply doubling the size of the wall.

INFINITY STEREO SPEAKERS
INFINITY STUDIO MONITORS SM-152 / SM152 
Circa 1989-94
SOLD 12/27/2023
TO VINCE IN COLORADO
HUGE in both size and SONICS! If you want to GET REALLY LOUD, then these Infinity SM-152's are the ticket. This was their TOPL for that series. 3-Way, Bass Reflex cabinet design. If you want a speaker to GET LOUD and not worry about, these are about as beefy as you're going to get without going to a pro-audio, S/R speaker and still get Hi-Fi detail. Plenty of top end that can be filtered / tailored to your tastes with built-in attenuator or external EQ / tone control. Also DEEP low-end due to rear porting, that still stays incredibly tight (shakes the concrete floor in our demo room). They are able to handle "power" better MUCH than your average speaker. Not simply referring to they're wattage rating, but just the way the perform at higher power / volume levels without "falling apart" sonically. We 'stood' on them HARD with our test Hafler power amp. I sold 'Pro-Audio' for years, and these would 'hold a candle' to many of those speaker models for power handling characteristics, but with 'Hi-Fi' sound quality / detail. Among the top performers of the many speakers we have auditioned over the years. 
Our speaker tech has completely gone through and 'Certified' these.  Both woofer surrounds replaced with new foam for trouble-free service  (YES, 'properly', using voice coil shim method!!!). Woofer dust caps replaced with vented cloth domes instead of the fragile 'foam' versions. We also added additional, Poly-spun batting to tighten up any 'hollowness' from the cabinet. All drivers were re-installed with the addition of gasketing material to further seal and eliminate any ‘flange to baffle’ rattles and buzzes. Attenuators removed and cleaned for ‘static free’ operation. Gasketing also added to the attenuator plates prior to re-installation as well. Following that work, we completely tested them with W/N 20-20k and swept them with our AF generator from 20-5,000 Hz, feeding them with the output from our Hafler 500 Pro Power Amp, looking for any vibrations or other anomalies (and there were originally a few that we addressed, as there typically are on speakers). Then further auditioned with a myriad of our difficult to reproduce 'test' CD's.

Infinity SM-152  Features: 
   
- 15" Heavy-Duty, Poly Coated Low Frequency Driver (Woofer) with fresh foam surrounds installed
- 2x 4.5", Poly-coated, midrange drivers
- 1" Ultra-Low mass, 'High Output', PolyCell Dome Tweeter
  - "Real" internal cross-over, not just a couple of "caps" on the mids and tweets
- Variable-position Hi and Mid frequency attenuators for custom tailoring sound to your tastes and listening room
- 4.5" tuned port on rear panel for extended low end
- Standard, Push clips for receiving 'bare wire' or 'gold pins' in input cup
  
Infinity SM-152 Specs:

Frequency Response: 29-27,000Hz ±3dB, 44-25,000Hz ±3dB
Efficiency: 102dB 1w @ 1m
Nominal Impedance: 8Ω
Cross-over frequencies: .5kHz & 5.5kHz
Recommended Minimum Power Amplifier output: 10 Watts
Recommended MAX Power rating: 300 Watts
 
These are impressively large speakers. Very nice looking wood grain, vinyl wrap cabinets. Only cosmetic issues are that there is an old a repair to the back, edge of one cabinet that had been done prior to arrive to us. There's a few scuffs on the top of primarily one cabinet, and the grill cloth on each has a hole in the knit (see photos above). The grill frames are perfect with not breaks, or missing locate pins. They're all intact. Again woofer just had fresh, new foam surround installed for trouble-free service.
Speakers look and sound GREAT! Huge, accurate and loud sound, but also very efficient at lower powers due to their 102dB rating! I hope you don't have any neighbors within a couple miles as these are capable of MASSIVE BASS!!! (actually the most bass response of any speaker I've come across in over 4 decades that wasn't a 'subwoofer'). If you're looking for a great performing speaker all the way from 'low' (again, 102dB @ 1 Watt) to very high volume applications with that big 'Wall-O-Sound', or want to throw parties every weekend you will not be disappointed with these speakers. I've actually had these speakers held back here at the shop for me to listen to for a few years. I can attest that they are pretty much not only one of the loudest speakers we've ever had, but also due to their accuracy, and balance / detail, one of the most fun to listen to, for any type of music we've thrown at them. I run them typically with a big Hafler power amp, but with their "102dB" rating, you could likely get away with something as low as 50-60 Watts and be happy (although as typical, "the more the better"). Each measures 40" tall x 17.75" wide x 12.5" deep and weighs 65 lbs unpacked. Includes our standard 30 day limited speaker warranty ( & excluding problems due to under / over powering)

So normally we don't sell any 'un-refubished / un-serviced / un-restored' vintage audio, but will make an exception here. I've owned these speakers for many years with plans to refurbish them, but we have WAY TOO MANY speaker projects ahead of us that are 'lower hanging fruit'. With the exception of the missing midrange, all the drivers function. Both woofers will of course need new foam. One of the woofers needs work to one of it's spider wires. There's some veneer issues that can be addressed if you have the skill sets. I did not get any grills with them. All of the drivers and crossovers are original (the crossover says "15T") These Cerwin Vega crossovers were silk-screened for the 15T model, and then for the "417R", they simply put a sticker over the "15T". That sticker has since fallen off of both of these. We applied some lemon oil to one of the cabinets to give an idea of what they 'could' look like.
With their 103dB efficiency rating, these would compare to some of the classic Klipsch and Altec VOC designs.
These are also listed as their separate parts on our CV parts page, and will get pulled from sale as shown above if parts sell first.

German made Magnat MSP-300 tower speakers, These were their second from the top of the line at the time. Designed for more discriminating Hi-Fi listeners with above average gear & ears (not referring to 'hearing ability', but to 'listening ability'). Artfully designed and quality constructed equaling a payoff of sonic excellance.

MAGNAT MSP-300 FEATURES INCLUDE:

- 3-Way, 3-Driver, Air-Suspension / Infinite Baffle cabinet design
- Dual 178mm / 7" Low Frequency Drivers (woofers), Non-deteriorating, Butyl Rubber surrounds, Polypropylene coated cones & 'Ribbon-Wound'VC's.
- 83mm / 3.25" Midrange Driver featuring, Gusseted Cast-Alloy frame, Non-deteriorating Butyl Rubber surrounds, Polypropylene coated cones & 'Ribbon-Wound'VC's.
- 25mm / 1" 'Soft-metal' Dome Tweeter ("The 'soft metal' dome is made of an ally said to combine lightness and rigidity with enough internal damping to eliminate most high-frequency audio resonances. Such resonances often occur with diaphragms made of hard metals such as titanium or beryllium")
- Internally braced cabinets to reduce unwanted resonances and 'ballooning' effects
- All drivers wound with 'flat / ribbon' wire (from an original brochure / review, "The wire is wound edgewise on an aluminum former in Magnat's tweeters and midrange drivers, but in the woofers the wire is wound flat in five layers. The close packing of the ribbon wire enables the Magnat drivers to have about 40 percent more copper in their magnetic gaps than drivers made with conventional round wire, which improves their magnetic efficiency and heat-dissipating qualities.")
- Heavy 5-Way Binding Posts
- Cabinets completely 'packed' with spun-glass damping material

MAGNAT MSP-300 ORIGINAL SPECIFICATIONS / SPECS:

Here's a link to an informative Magnat MSP-300 Review / Brochure; http://www.hifi-classic.net/review/magnat-msp-300-151.html

The tall 'tower' stature of the Magnat MSP-300 speakers puts the tweeter more on plane with your ears, instead of your knees.
Our speaker tech has completely gone through and 'Certified' these. We originally found a continuity issue with the input panel to crossover connection that was causing a minimum 10 Ohm increase on one of the speakers, manifesting a symptom of a loss of power from the amplifier. Once that was addressed, the DCR was corrected, thus allowing all the power to reach the crossover. Once re-assembled, he completely tested them with both recorded material, W/N @ 20-20k and swept them with our AF generator from 10Hz-25,000 Hz and feeding them with the output from our Hafler DH-500 Pro Power Amp, looking for any irregular vibrations / anomalies in either the drivers. driver mounting, crossovers or cabinet structure integrity. We then further auditioned with a myriad of our difficult to reproduce 'test' CD's. They performed and sounded great!
In auditioning these speakers I tried about every genre of music, including most of the selections listed on our 'Demo Cuts' page but here are some notes I made on their post restoration 'check sheet'; TLC's "Scrub" from their album 'Fan Mail', did 'sub-bass' note @ 1'25" & 1'35" SO SOLIDLY & PROMINENTLY THAT IT SHOOK OUR CONCRETE FLOOR (and that is a 'tell tale' indicator of how most of the rest of the testing would go), Dire Straits' "So Far Away" from their album 'Brothers in Arms', Donald Fagens, "I.G.Y." from the album "Night Fly" "Was as expected from any speaker. Good power and 'snap', great balance, and fine WITHOUT an EQ!", '24K Gold Edition of Jennifer Waren's "Famous Blue Raincoat' "had great detail across the board"', Cowboy Junkies's version of "Sweet Jane" "was very natural. A bit of EQ (R&R 'smile') eliminated a bit of a 'contained' character. Heavy Rock was actually a 'Forte' of these speakers including; Trapt's "Headstrong" "which was quite 'Solid and Punchy" as was Korn's version of "Word-Up". These speakers also did quite well with 'Big and Brash' orchestral movements (I tried quite a few different cuts). Calvin Hampton's, "The Wedding March" from "Digital Pipes, The Splendor of the Organ" a digital recording of a cathedral pipe organ, was "BIG AND OPEN" without any external processing, Cathedral Choir selections (I have a few digital recordings from some I've traveled to in the UK) were very natural, but really opened up with some added EQ. Piano was, "natural and fairly open", and a few others, all digitally recorded and some 'DDD'.

Magnat manufacturers it's own drivers (in fact, they supply some drivers to "Wilson" speaker company for their $65,000 model). They are super quality built featuring top quality drivers, cabinets and an incredible crossover in each cabinet.
Actually, 'very good' power handling characteristics. They are able to handle "power" better than your average 'tower-style' speaker. Probably due to the two 8 Ohm woofers wired in parallel in an 'Infinite Baffle' cabinet. We 'stood' on them to a reasonable degree with our test Hafler 485 Watt power amp, even with Korn's version of "Word-Up".

The 'Piano Black', gloss finish tops have some scratches (our tech was able to improve them compared to how they arrived), but they're not anything that will 'stand out' unless they're standing in direct sunlight (which would be a bad idea anyway). The balance of the cabinets in great shape as are the grills and grill frames. There's a few minor scratches here and there to the 'gloss finish' of the Mahogany, but nothing at all distracting (we tried to show them in photos above as best they would show up).
Great speaker for up to mid-high volume levels.
Great for most Jazz, and percussive jazz, brass / horn section, 'punch, well mixed modern music (think 'YAZ'), 'percussion heavy' selections / music. Very accurate, detailed & 'refined' sound, and while they are 'detail oriented', they handle power surprising well.
Consecutive serial numbers; #41 & #42! Cabinets measure 40" H x 11.5" W x 11" D and weigh a 60 lbs each. Includes our standard 30 day limited warranty (excluding problems due to under / over powering).

These speakers are all about 'IMAGING' in a definitive 'listening space'.
If you are a classical or 'modern' Jazz fan and can afford to have a designated 'sweet spot' listening area, then you'll love these speakers. Also great for folk rock and easy rock. If you're a 'rocker', need 'tunes for your parties' or want speakers to 'passively' listen to from anywhere in the room, then these are NOT the speakers for you. If you appreciate very 'natural' reproduction of vocals, horns (especially sax and clarinet), pianos, jazz drums and percussion, then these speakers will be marvelous!
Again, these speakers are best 'on-axis' with the listening area in the 'sweet spot' (if you're not sure what that means, give me a call).

ADVENT 'LAUREATE' FEATURES INCLUDE:

- 2-way, 3-Driver Acoustic Suspension
- Dual 6.5" Low Frequency Drivers (woofers). Fresh foam surrounds just installed for trouble-free service
- 1" Dome Tweeter

ADVENT 'LAUREATE' ORIGINAL SPECIFICATIONS / SPECS:

System design: 2-Way, 3-Driver Acoustic Suspension / Infinite baffle
Frequency Response: 42-23,000Hz +- 3dB
Nominal / Minimum Impedance: 6/4Ω
Efficiency: 90dB 1W@ 1m
Cross-over frequency: 3kHz
Recommended Minimum Power amplifier rating: 10 Watts

The tall 'tower' stature of the Advent Laureate speakers puts the tweeter more on plane with your ears, instead of your knees.
 Our speaker tech has completely gone through and 'Certified' these. All four woofer surrounds just replaced with new foam for trouble-free service. Following the above work, we completely tested them with both recorded material, W/N 20-20k and swept them with our AF generator from 20-5,000 Hz and feeding them with the output from our Hafler P-225 Pro Power Amp, looking for any irregular vibrations / anomalies in either the drivers. driver mounting, crossovers or cabinet structure integrity. We then further auditioned with a myriad of our difficult to reproduce 'test' CD's. Entire cabinet has been frequency swept while being powered by our Hafler test amp. They performed flawlessly and sounded great!
Real Pecan wood veneer cabinets in beautiful shape as are the grills and grill frames. Really no cosmetic issues to speak of. Cabinets just had a fresh rub-down w/ lemon oil to bring out their original luster.
Great speaker for up to mid volume levels. Again, these are more "detail" oriented speakers NOT "Power Pounding Party" speakers. If that's what you're looking for then don't buy these. These are true to the classic New England speaker sound. Again as we mentioned earlier, placement of speakers / listener, while most times is important, is imperative with these speakers. If you can afford the space to arrange yourself, in correct proximity to these (between 1 to 2 x d, call me for clarification) you'll be amazed with the 'presence' of these speakers. Great for most Jazz, and percussive jazz, acapella vocals, acoustic guitar recordings, blue-grass, gypsy jazz & classical / symphonic / string music. Very accurate, detailed & 'refined' sound! Consecutively serial numbered pair. Cabinets measure 33" H x 9.25" W x 12.5" D and weigh 38 lbs each. Includes our standard 30 day limited warranty (excluding problems due to under / over powering).

These are great performing speakers for small spaces as reproduction speakers, and also make great "near field monitors" for the project studio. Loaded with Northern Euro drivers, an incredibly well built original crossover and internally wired with 14g wire. Cosmetically they are in fine condition as they have been professionally 're-veneered'  and have a natural 'oil' finish. The speakers have been through our standard, rigorous test procedures and passed with flying colors.
Our speaker tech has completely gone through and 'Certified' these. We have completely tested them with both recorded material, W/N 20-20k and swept them with our AF generator from 20-5kHz. Much more than your average "satellite" speakers. Also great for small Stereo Systems or for Near Field Studio Monitors.

Features:

- 3-Way, Acoustic Suspension Speaker Design w/ 'Bi-Amp' capabilities and an extra tweeter in 'Rear-Firing'" position
- 6.5" Poly Woofer with non-deteriorating, Butyl rubber surrounds for trouble-free service
- 1" Front Firing, Soft dome, VIFA, Poly Soft Dome tweeter from Denmark
- .75" Front Firing, Dome tweeter from Denmark
- "Real" internal crossover (not just a cap on the tweeters) that is incredibly well built
- Dual sets of Banana input jacks that are 'Bi-Amp' capable.
- 'Defeat' switch for the 'Rear-Firing' tweeter

Specs:
 
Frequency Response: 70Hz to 20kHz ±1.5dB
Sensitivity: 90 dB 1W@ 1m
Nominal impedance: 8 Ω
Crossover Frequency: 2.2kHz
Minimum power amp rating: 15 Watts

Input is via recessed, 3-way, "banana" binding posts! Again, the cabinets have been 'pro' re-veneered in Pecan and stained in a light Cherry, with a natural 'oil' finish. The original black, knit grill cloths also in great shape as well.
Great sounding with sonic detail and balance. Great for smaller systems or for surround speakers. These are small "bookshelf" / wall-mount size speakers so their height and foot print is minimal. We have completely tested them including sweeping them with an audio generator looking for any acoustical anomalies or extraneous noises or sounds. They look, work and sound great! Will come with 2 pair of 'Banana' jumpers for running speakers with a normal 'Full-Range' / 2-Channel receiver/amp. Each measures 16" high x 11" wide x 7" deep and weighs 24 lbs unpacked. Includes our standard 30 day limited warranty (excluding problems due to under / over powering.

CLASSIC & VERY EARLY FUKUIN ELECTRIC CO. / PIONEER HI-FI / STEREO SPEAKERS
PIONEER "TITAN IV"? SPEAKER
Circa 1960-61
for sale
SHIPPING TO JOHN IN FLORIDA
5/13/2021
Massive and VERY EARLY Pioneer 'Hi-Fi' speakers, direct from Japanese market. These appear to be original, factory built, Pioneer Titan IV speakers. The 1960 driver complement in these were typically offered in the US as 'kit' form (due to impracticality of SHIPPED such voluminous cabinets from Japan) but according to their consignor, these were brought over by a GI on military transport, so economics was not an issue. He purchased them originally in Japan. These are among the first drivers branded 'Pioneer' from the original parent company Fukuin Electric Co. The company changed it's name to Pioneer in 1960 or 61. There are probably less than an 'handful' of these in the US (if that) and probably only a few dozen in the world. If you want the rarest of the rare Pioneer speakers, here you go. These things are MONSTROUS!
"Hey, Go Big or Go Home!"
Their huge drivers are both efficient and seem to be power capable (handled our Hafler P225 well, but as always, be careful with irreplaceable 'vintage speakers).
Our speaker tech has completely gone through and 'Certified' these.
He has completely disassembled them further, testing all drivers independently. No material issues found with any of the drivers. Each was 'swept' with the AF generator while removed. All drivers were re-installed with the addition of gasketing material to further seal and eliminate any ‘flange to baffle’ rattles and buzzes. Attenuators removed and cleaned for ‘static free’ operation. Gasketing added to the attenuator plates prior to re-installation as well. We also 'modernized' the input connectors (gasketing also added to their mounting plates). Gasketing also installed on rear panel, prior to re-installation. He also installed new, height adjustable, leveling, 'glide' feet. Entire speaker system then swept with our AF generator from 20-5,000 Hz and feeding them with the output from our Hafler P-225 Pro Power Amp, looking for any irregular vibrations / anomalies in either the drivers. driver mounting, crossovers or cabinet structure integrity.  Next we auditioned them with our standard, 'abusive' demo / testing CD's / cuts running the gamut from Dire Straits, 'Brothers in Arms', TLC 'Fan Mail', Allison Kraus and Union Station, Nickelback, a digital recording of a cathedral pipe organ, our 'Usher Speaker' demo CD (no not that Usher), 'Friday Night in San Francisco', with Al Dimeola, John McLaughlin and Paco DeLucia, Nickel Creek's, "When in Rome" from the CD, "Why Should the Fire Die", Jennifer Warnes, "Famous Blue Raincoat", and a few others, all digitally recorded and some 'DDD'.
Very 'large' sounding cabs. I did prefer them with an EQ, but I know you 'purists' would 'cringe' at that idea.
 Pioneer Titan IV Speaker Features include:
 
- 3-way, Bass-Reflex design
- 12" Pioneer PW-30C, Cast Aluminum frame, Low Frequency' Driver (woofer) w/ vented Voice Coil and AlNiCo magnet / motor.
- 6" Pioneer PM-16B midrange 16 Ohms & AlNiCo magnet / motor.
- 3" x 2.5" Pioneer PT-6, 16 Ohms Horn Tweeter w/ AlNiCo magnet / motor.
- Infinitely variable L-Pad for Tweeter attenuation
- Pioneer DN-7 2-Way / 3-Way Crossover
- 11.5" x 8" Tuned Port

Pioneer Titan IV Speaker Specifications:

System Design: 3-Way, Bass Reflex
Driver Compliment: PW-30C 12", Cast Frame Woofer, PM-16B midrange / Squawker, PT-6 Horn Tweeter & DN-7 Crossover.
Frequency Response: ~35-20,000Hz
 Nominal Impedance: 16Ω
 Cross-over frequency: Pioneer DN-7 500Hz & 4kHz @ 12dB / Oct
Power rating: likely 25-40 Watts
 
The real wood, Mahogany veneer cabinets in INCREDIBLE shape, as are the original grills. They are virtually blemish / mark free and look like they could still be on the original show room floor. The cabinets have just had a fresh coat Howards 'Restore-a-Finish' and 'Feed-n-Wax' rubbed in to bring out their original luster. Again, our speaker tech has completely refurbished, tested and Certified these speakers performing the previously mentioned processes.
 Great speaker for a lower powered 'vintage' Hi-Fi system, or that low wattage or 'single ended' tube amplifier. They look, work and sound great! Cabinets measure 38" H x 27.25" W x 17.75" D and weighs a hefty 90 lbs each (due to their huge size once packed, the P,S & I on these to much of the lower 48 states of the US would run approx $450-$650. Locations such as North Eastern States, North Western Washington or Southern Fla would run more). Includes our standard 30 day limited warranty (excluding problems due to under / over powering.
