  In perfect cosmetic condition, 100% original and functioning perfectly, this pair of PSB Image T6 tower speakers come with the original factory boxes and packing materials.  They have the cherry veneer finish.
  On the rear they feature dual gold-plated binding posts and jumpers.  The adjustable feet come with the optional rubber levelers.  When introduced in 2010, the original MSRP for the pair was $1200.  
• Lab testing done by The Absolute Sound had them conclude that the PSB Image T6 "is an absolutely wonderful full-range speaker".  At the time, they considered the Image T6 as their new "standard" for an "entry-level high-end loudspeaker in the $1000+ price range."
  
  Each of the enclosures feature a single 5.25" clay/ceramic-filled polypropylene midrange driver in its own sealed chamber, augmented by two 6.5" clay/ceramic-filled polypropylene woofers, with each woofer housed in its own individually ported chamber.
• The mid/bass and bass drivers feature magnetically neutral polycarbonate baskets and rather than the typical dust caps, the T6 has bullet-shaped *phase-plugs to enhance “linearity at high frequencies.”
• The driver mounting flanges and bass reflex ports are fitted with smoothly contoured rubber “boots” that reduce diffraction and give the speakers a “no visible fasteners” look. The cabinets have 1.2" thick, rigid, contoured front baffle plates all wrapped in gently curved cabinet edges, which creates the illusion that the cabinet sidewalls are curved (though in fact they are not).
  
  *NOTE: A phase plug is a fixed, shaped component at the centre of a loudspeaker drive unit that controls how sound waves leave the cone, reducing internal reflections and phase cancellation for a smoother, more coherent high-frequency response.

About PSB...
The Canadian-based PSB has been in continuous operation for over 50 years since it was founded in St Jacob’s, Ontario by classically trained violinist and self-taught acoustics designer, Paul Barton, and a couple of his school friends.

The three letters in the company name stand for “Paul and Sue Barton” (he and his wife of over 50 years). Founded in 1972, PSB is located in Pickering, Ontario Canada, and Paul’s work both at the NRC (National Research Council of Canada) with Floyd Toole and independently has helped shape a continuing advancement and revolution in loudspeaker design and performance.

Marrying psychoacoustics research with loudspeaker design, Barton took a scientific approach to designing loudspeakers that was rare at the time. Over the course of the late 70's and 80's, he conducted thorough and detailed measurements of loudspeakers at the National Research Council (NRC) in Ottowa, Canada, utilizing its state-of-the-art anechoic chamber and instruments to perfect the signature sound of PSB Speakers that are so well known today.

Now, as part of the Lenbrook Group of companies, Mr Barton continues to spearhead design and development on his namesake brand but also assists sister company NAD with the development of certain products. In 2018 he was honored with a Lifetime Achievement Award at the Toronto Audio Fest commemorating his almost five decades of work in loudspeaker design.

Mr Barton has consistently contributed to the audio scene as we know it and he shows absolutely no sign of slowing down!

(mid 70's)  $425

Hard to find in such excellent cosmetic and operating condition, this pair of the highly regarded ADS L500 was manufactured by ADS (Analog and Digital Systems) in Wilmington Massachusetts USA. They use the well renowned Braun drivers which were manufactured in Germany. These speakers, when driven by a quality amp capable of handling 4 ohms, sound excellent in a "typical" listening area.
They also have satisfying bass considering the size of their walnut veneer cabinets. 

The all original Braun 8" mid-bass drivers *(with Stifflite cones), tweeters and crossovers are in perfect operating condition.  There is literally no dust on the tweeters.  As is probably known to many, the Braun tweeters were factory coated with a sticky material to help damp the resonances.

The ADS L500 speakers were originally designed by the world-famous Dieter Rams, the industrial designer who designed many of the Braun products of the same era. The New York Museum of Modern Art is loaded with Dieter Rams' and ADS' works.

*NOTE: Stifflite is a relatively thick material formed of air-filled, randomly-oriented pulp fiber in a unique "sandwich" construction.  Because of this unique design, Revox, Braun, Visonik and ADS firmly believed it had the closest thing to the ideal woofer cone.

The ADS L500 was developed right along with their more expensive studio speakers for the best possible reason: they wanted to create a coherent line of loudspeakers where every model, regardless of price, would have to reproduce musical sound with an optimum of clarity and a total absence of coloration.

When their engineers finally were able to meet these criteria, they called this remarkably open quality the 'Invisible Sound' of ADS. Since theirs introduction they have become one of the standards of excellence for many professionals and dedicated audiophiles.                                                               

The L500 shares with all other ADS systems the 'Invisible Sound' and the technical refinements that make that faithful response to the input signal possible. For instance, they installed only one type of soft-dome tweeter, a masterpiece in sophisticated audio design. Also, all ADS speakers utilize similar small-diameter woofers and the same computer-grade materials for the crossover networks. The craftsmanship and materials that went into every cabinet are of uniform, high quality.  These dedicated design parameters enabled ADS to become one of the premier loudspeaker companies.  Even today, there are clubs, podcasts and groups of ADS owners worldwide that continue to marvel and appreciate that unique "ADS sound".

About a/d/s ADS/Braun...
ADS (Analog & Digital Systems) was the American importer's company label. Braun was the original German company which built the raw drivers and to some extent had a small, popular line of (fairly conventional) Braun speakers, tape decks and amplifiers for sale in Europe. The most common link to the ADS/Braun line was a Dr. Gunther who wished to import the products and traveled around to dealers trying to stir interest in the late '70's when Germany was not yet on the US audiophile map beyond Dual (from the Black Forest area) and a by then less well known Blaupunkt. (Studer and Revox were both Swiss companies distributed originally through German lines.)

Eventually, enough dealers signed on to a commitment and Gunther established ADS as the "manufacturer" of the speakers in the US. This was fair at the time as many companies were using drivers sourced from various manufacturers around the world and subsequently designing and building their own systems with either off the shelf drivers or custom modified drivers from a larger company. The original Boston Acoustics line came down in lineage from the KHL/Advent company but sourced their midrange and tweeter from Vifa and Seas while the woofers were manufactured in house but due to time restrictions on the company launch the A200's original woofer's ceramic magnet was charged at the AR factory in Cambridge, Mass. A largely similar story exists around EPI and the original Genesis line from Cambridge where nepotism in speaker design was commonplace amongst the numerous MIT students who had worked with Vilchur or Kloss or one of their students/business associates.

At ADS, Gunther hired a designer (some say it was Michael Kelly) to build finished speakers around the Braun drivers. Another company built cabinets here in the US to ADS' specifications. Kelly managed some fairly industrious and unique designs for ADS which drew significant attention to the ADS line. As the ADS line grew in stature and sales, Braun took notice and thought they could do just as well or better under their own name by trading on the popularity, reputation and success of the ADS line. The problems started with the issue of Braun having to import entire speaker systems which meant fairly heavy cabinets were being shipped across the sea incurring added expense not seen in the ADS line who had only been shipping raw drivers. ADS and Braun existed for a time as distinct lines with only passing similarities yet in discrete dealerships which led to many conflicts of interest and many awkward questions for everyone concerned. Braun's answer to this pricing issue was to cut off ADS's access to many of their most successful drivers. Suddenly ADS was in danger of being put out of business without a product line along with not having any backup drivers for repairs. Promises to dealers were being broken on a daily schedule as both revenues and resources dried up. Many of Kelly's designs were difficult to drive and required high power yet the Braun drivers were not meant for high power handling. This led to numerous repairs being done by dealers. Day by day, many dealer's repair facilities were stacking full of broken ADS speakers waiting for parts that never came.

There was a short compromise where ADS/Braun speakers existed as one line but Braun soon found themselves under commitment to repair existing ADS/Kelly designed speakers while not having the benefit of using all of Kelly's designs - many of which Braun disapproved of due to their reliability issues and their not being "perfect" examples of Braun design skills (which were not of the type desired by the average US audiophile of the day). 

New dealers had been established for the ADS/Braun line separate from the original ADS and Braun dealerships, many original ADS dealers were left out in the cold without any factory backup and new Braun dealers were expected to use their own resources to fulfill ADS's commitments to parts and service. Court battles quickly and seemingly endlessly ensued. Eventually ADS was subsumed and then ceased to exist as a distinct company. Braun speakers went on in the US for a few years without most of the innovation of the ADS/Kelly designs and eventually faded ingloriously from the US market. Memories from customers ranging from fond to highly upset and generally hard feelings from dealers who stuck it out too long or hoped to make a quick buck off someone else's efforts were all that were left...

About Ohm...
Ohm was founded in 1972 specifically to develop and market speakers based on *Lincoln Walsh’s patented design. The first model, the Ohm A, is still considered one of the all-time best speakers ever produced. In 1981, John Strohbeen (Ohm’s president) patented a design that addressed three issues with the original speaker
~Now the stereo imaging could be heard from most listening positions,
~They can now be used near walls and
~Normal amplifiers could drive the design while high power would not destroy them.     
Ohm went factory-direct in 1999 and redefined the speaker line-up from the traditional good-better-best (as the price went up) to the-best-we-can-make for small, medium and large rooms.  Still in business today, Ohm's reputation is regarded as exceptional across the world.  The entire Ohm line, and, in fact, the company itself, owe their existence to the Walsh driver developed by the late Lincoln Walsh (1903–1971). This driver, in principle, can operate over the entire audio bandwidth from 20Hz to 20kHz and is capable of producing a coherent cylindrical soundfield around the driver cone. It is a dynamic moving-coil design but with strikingly unconventional and original packaging. Sound is radiated from the surface of an inverted cone that visually resembles an upside-down woofer or a very large ice-cream cone. The face of the cone radiates into an enclosure and generates what is equivalent to a backwave from an ordinary driver.

('85-'88)  $400 (stands included)

In very good cosmetic condition, completely original and operating perfectly, this pair of KEF C40 was an iconic British design from the mid 80's.  They are generous in both volume and drive units. 

Bass is plentiful and extended, and the design is balanced to operate clear of room boundaries (on a specific type of stands).Designed as a 2.5 way system, the twin 8" mid-bass drivers (featuring "no maintenance required" polypropylene cones) handle the lowest frequencies.  They augment and extend bass output, substantially improving power handling capacity, and assisting bass damping. 

To handle the high frequencies, the KEF C40 used their excellent T33 tweeters.  These were actually made by the highly respected French speaker company Audax and were designed specifically to KEF's specs.

These were top of the line in the KEF C Series that was built from '85 to '88. KEF described this C40 design as a "2 & 1/2 way" speaker, in which the bottom mounted driver acts as a subwoofer to handle the very lowest frequencies. The versatile C40 can be used either as a compact floor-standing speaker (or it can be placed on the included low stands as shown in the photos.)  It is built to effortlessly handle 100 watts and it has all of the exceptionally accurate, warm and musical reproduction that built KEF's reputation in the '80's.

Here's another excellent description of the C40:
The C40 (a successor to the KEF Carina) added a second B200 unit operating at low frequencies only. These two 3-ohm B200s have a free-air resonance of 40Hz. The two together, connected in series to give 6 ohms and shunted by capacitors of 10μ and 100μF respectively, produce a resonant frequency of 85Hz in this quite large box. KEF have reverted to third order loading here, with a 450μF capacitor in series and this has resulted in a nice clean bass end of apparently limitless power. A low floor-stand is suggested, but operation on the floor itself is not out of the question and was indeed preferred on some program material. The cabinet coloration is now low down and comparatively innocuous; the sibilance is still present but less obvious and, if the loudspeakers are being used on the floor, one is automatically off-axis vertically. Driven by a pair of 100-watt amplifiers, these C40s with their true sensitivity of 91dB at 8 ohms, are capable of very loud sounds indeed and they remain clear and undistorted right to the amplifier limit. This is a level at which I feel inclined to leave the room but, as KEF succinctly put it, "it will be particularly appealing to the cost-conscious rock listener.
The system can go exceedingly loud, can handle plenty of power, and, with a generous bass delivery, is particularly suited to good ol' rock n' roll...the so-called "West Coast' sound.

Basic specs:
Nominal Impedance: 8 ohms
Rated maximum power: 100 watts
Frequency response: 68Hz to 20kHz +/-3dB (-6dB at 58Hz)
Sensitivity: 91dB
Maximum output: 111dB peak under typical listening conditions
Weight: 22 lbs each
Dimensions: 25.5"H x 10"D x 9.75"W

About KEF...
It all began in 1961, as it so often does, with one man who was somewhat detail-obsessed. And in the world of hi-fi (or indeed, anything grounded in innovation, technology and perfection), that man, was Raymond Cooke, a former technical director for Wharfedale speakers (England).  In the beginning, their tendency to sell raw drivers to their competitors – rather than keep them for themselves  – solidified them as true leaders in this field.  They went on to produce the K1 Series but with the 1962 introduction of the now world famous B139 bass driver, the Celeste was born. It proved to be a best seller but it wasn’t until the 1970s that their real breakthrough occurred.  After a series of very successful commercial loudspeaker designs, 1975 saw a development which placed KEF on the hifi map. Indefinitely.

Thanks to the first implementation of computers in the design and measurement of their loudspeakers, this lead to the world famous

KRF Reference designs emerging for the first time, from the 101 all the way through to the 105.2. The first of many lines of References, each dominating its market.
Everything about what KEF has produced since day one has screamed of quality, of innovation and of style… three very memorable qualities. And when you have a company history (not to mention product range) as long and as illustrious as KEF’s, there are some seriously impressive things to remember.

('93-'96)  $400

In excellent cosmetic condition, 100% original and fully tested, this pair of Paradigm 9SE MK3 speakers come with the original boxes and packing materials.  The "SE" stands for "Special Edition".  Real mahogany veneer on top adds a touch of class to the black ashwood enclosures.

Back story:
The common problem faced by 2-way speaker systems is the compromise of sacrificing high efficiency for deep bass. The 9se MkIII solves this problem. Its twin 8" bass/midrange driver configuration simultaneously provides high sensitivity, deep power full bass, high power handling and a dramatic reduction in distortion, especially at high sound pressure levels.
Paradigm could not accept the "high-efficiency for deep bass" sacrifice in the design of a larger 2-way model. The 9se MkIII is the culmination of this attitude, ... a high-performance 2-way design capable of out-performing systems costing several times as much.

Specs:
3-driver, 2-way bass reflex, quasi-3rd order resistive port.
Crossover: 3rd order electro/acoustic at 2,0 kHz
Tweeter: 1" treated textile dome with aluminum former, ferro-fluid cooled and damped.
Mid bass:  two 8" drivers with diecast chassis, polypropylene cone and Apical formers.
Low frequency:  32 Hz 
Frequency response:  ±2 dB from 45 Hz - 20 kHz
Sensitivity: 93 dB
Recommended amp:  15 - 200 watts
Nominal impedance:  6 ohms / 4 ohms

About Paradigm...
In 1982, Jerry VanderMarel, a seasoned veteran of consumer electronics and loudspeaker sales, teamed with Scott Bagby, a loudspeaker designer with a long history of innovative ideas. Together, they went back to the drawing board and developed a radical new speaker. To find the sweet spot, they tapped university audio researchers and detailed scientific findings from the audio studies conducted by the National Research Council of Canada. The point was to achieve a level of performance that would erase the speaker itself from the equation. Pure, lifelike audio, uninhibited by coloration, unrestrained in its ability to translate power into sound. And to do it at a price that would allow anyone to experience this magic. The Paradigm Models 7 & 9 were unveiled at the Toronto Audio Show that year. Immediately, a dozen dealers signed on to carry the line. (Many of these loyal charter dealers remain proud Paradigm dealers even today!)
