Tannoy Sensys 1 

('02-'06)  $450

*Why bother with frequencies that only your dog can hear?

In absolutely pristine cosmetic and operating condition, this pair of Tannoy Sensys 1 are rarely seen in the wild.

With the introduction of Sensys, Tannoy has combined the core element of sound quality with the other equally essential ingredients, cutting edge technology, clean aesthetic design and affordability, to produce a class leading range of exceptional loudspeakers. Avoiding visual tricks that often cause designs to quickly date, the refreshingly uncluttered appearance of Sensys is as reassuringly unpretentious as it is timeless.

The Tannoy Sensys 1 features Tannoy's Wideband technology and follows a minimalist signal path by virtue of the inherently simple crossover.  This simplicity is needed as the drivers are in a naturally phase correct alignment and the integrated design allows for a seamless frequency transition. Sensys 1's high power handling capabilities and high efficiency make for one extremely dynamic package that became a classic and a favorite of audiophiles. 

With a 7” cast chassis mid bass driver and 1" WideBand high frequency unit this is a bi-wireable stand-mount speaker of immense ability. Combining tremendous bass weight and impact with natural open voicing and sound staging.

About Tannoy's WideBand technology...
Tannoy has pioneered wide bandwidth audio reproduction in its high-end loudspeaker designs. The undisputed benefits of extended high frequency performance have been recognised by audio enthusiasts and recording industry professionals worldwide. Tannoy has received many international awards for products utilising Wideband technology. Although developed in parallel with the emerging technologies of extended bandwidth SACD and DVDA players, their engineers have long since recognized the improvement that a Wideband Tannoy SuperTweeter can make to a system, even when using bandwidth limited conventional analogue or digital recorded software.

The key element to understand first of all is that Wideband performance drive units are not there simply to increase the amount of high frequency information you perceive, the acoustic benefit is much more subtle than that. It is the enhancement of the frequencies within the accepted audible band that makes this technology so special.

'Why bother with frequencies only your dog can hear?' This question, often asked, took them to the very heart of what Tannoy Wideband™ technology is all about: Musical instruments produce considerable energy above 20kHz and, with effects of harmonics and overtones, achieve frequencies well beyond what might generally be considered as the limit of human hearing. For instance, the over 20kHz energy of a trumpet, fitted with a particular type of mute, does not drop into the noise floor until 100kHz. Violin and oboe exhibit energy above 40kHz, while sibilants in speech can also be shown to have energy above 40kHz. Research has shown, through the measurement of brain wave activity, that humans do perceive ultrasonic components within music. Concluding that the mechanism of ultrasound transmission is through bone conduction, probably via an organ in the inner ear, called the saccule, to the cochlea, the organ responsible for hearing.

In addition, Wideband technology reduces phase error and significantly improves transient performance below 20kHz. This leads to increased tonal accuracy throughout the whole frequency range, even bass information is faster and tighter, effectively enhancing the total listening experience. Music, speech and soundtrack effects have an increased immediacy, airiness and impact, providing a performance that sounds more natural and true to life. Extreme physical demands are placed on the high frequency unit when performing at such extended bandwidth levels. The need to achieve completely consistent constructional and acoustic quality has led Tannoy to design and produce its own titanium dome driver at its Scottish based manufacturing facility.

About Tannoy...
Tannoy is a British manufacturer of speakers and PA systems.  Founded by Guy Fountain in London in 1926 as the Tulsemere Manufacturing Company, today the company is part of the Music Tribe group of brands.  They eventually moved to Coatbridge Scotland in the '70s.

Tannoy's image is particularly linked to both studio monitors as well as its Prestige range of home speakers. Prestige speakers use Dual Concentric cone speakers and are easily recognized by their "vintage" design. Tannoy is notable for its 'Dual Concentric' speaker design, which places the tweeter behind the center of the medium or bass driver. "Dual Concentric" is a trademark although Tannoy is not the only speaker manufacturer to design coaxial speakers.

In 2002, Tannoy was acquired by TC Group and TC Group was subsequently acquired by Music Group in 2015. Following the Music Group acquisition, it was suggested that the Coatbridge facility would be closed and all related activities would be relocated to Manchester England. In 2016, however, Music Group confirmed that Tannoy loudspeaker manufacturing would continue in Scotland, with a brand new manufacturing facility planned.


Mission 773

Mission 773

Mission 773 

 (England, late 90's)  $300

As with all the excellent British-built Mission speakers, the model 773 produces excellent sound.  We assume that most HiFi addicts (like ourselves) know about the British-built Mission loudspeakers.  For a long time in the '90's, the brand was ubiquitous, omnipresent and virtually synonymous with speakers in the way that Wharfedale was back in the '70's.

The Mission 773 enclosures have real and beautiful light oak wood veneer.  These are relatively small towers that are a biwireable 2 way tuned reflex system with front ports.

Each 33" tall enclosure has a single 1" viscous laminated dome tweeter and two 5" Audax *aerogel cone woofers (with **phase plugs instead of dust caps).  They each weigh about 21 lbs with a small 6.5" footprint.

The Audax Aerogel series of drivers feature a cone made of a unique acrylic polymer gel with a blend of Kevlar and carbon fibers embedded into it. The result is an ultra-light and extremely rigid cone that produces outstanding clarity, precise imaging and unequaled sonic definition. Developed for no- compromise high-end designs, these drivers make outstanding midbass and midrange drivers.


Phase plugs are sometimes used instead of traditional dust caps.  With a phase plug, the cone excursion moves in a very close tolerance around the stationary plug whereas a dust cap moves forward/backward with the cone.  A phase plug helps to reduce heat generated by the voice coil by allowing the heat to exit through the narrow circular gap of the plug.

Frequency response:  50 Hz - 20kHz ±3dB
Nominal Impedance: 8 Ohms
Amp Power: 25 watts minimum
Sensitivity: 88 dB
Crossover Frequency: 3000Hz

About Mission Electronics...
Formed in 1977 in Huntingdon England, Mission Electronics' first product was their 770 loudspeaker and they continue to build loudspeakers to this day. They have also built other Hi-Fi products including CD players, amplifiers and tuners etc. under their own brand name "Mission" and from 1984 under the "Cyrus" brand name.

In the 1990s, the Mission loudspeaker business was taken over by the Chinese owned International Audio Group (IAG), and the Cyrus Audio business became part of the NXT Plc group and then became a independent company in 2004.


Siefert Research Maxim III-H

Siefert Research Maxim III-H

Siefert Research Maxim III-H  

(mid 80's)  $500 (firm)  uber rare

This incredibly rare set of Siefert Research Maxim III-H speakers have been part of our personal collection for many years.  This matched set is in pristine cosmetic condition, completely original and operating perfectly.
As of this post (to our knowledge) this is the only pair of Siefert Research speakers available for sale in the USA.

The Maxim III-H is best described as being just one of the pure audiophile level Siefert Research models.   Regardless of which model was produced, all of them are extremely rare since they were never mass produced.  Each pair was hand-built in Malibu CA during the late 80's.

In our humble opinion...the Maxim III-H model fits our own personal definition of the "perfect" bookshelf speaker.  
These were 100% made in the USA (Malibu CA) and easily rivaled (and surpassed?) the acknowledged high quality of famous German/American/European speakers like Canton, Braun, ADS, Sonus Faber, etc.

The original designer, Dan Siefert (see his bio below) described the Maxim III-H as his last and best configuration of a two-way, front-ported, compact system featuring 40-Hz resonance woofers, low IM distortion, low group delay and high power handling capability (safe for use with amplifiers of up to 250 watts power capability). 

The cabernet oak veneer enclosures are substantially heavy with radius corners and the highest quality construction combined with the best components available at the time.  

The back story:  
It was several years ago (2014) when we first discovered Siefert's speakers.  We came across a pair that was unknown to us (at the time).  After being blown away during a test, we were intrigued enough to spend quite some time online to track down and email the designer, Dan Siefert. (see his bio below).  He was kind enough to reply with a wealth of inside information way beyond what was available online.  He also sent us a package with original spec sheets, sales sheets and technical design information about the Maxim lineup.  Here is his explanation as to what the "H" meant on these Maxim III-H speakers:

Dan's reply:  "With the Maxim III-H, you have what I consider the best series of Maxims. The "H" stands for hybrid. Looking at the tweeter you will notice that the dome is aluminum but the surround (outer edge) is not.  It's known that 99.9% of all dome tweeters are a single piece construction.  So, if you have an aluminum dome (high stiffness), the surround would also be aluminum. Aluminum makes a great diaphragm but a lousy surround (where you want high compliance, not high stiffness).  In the '80s there were almost no hybrid construction tweeters.  Today they are somewhat more common. Bottom line: my hybrid tweeters combined the high stiffness of an aluminum dome with the high compliance of a polyamid surround made a very good speaker even better."

Stereophile magazine 1985:  "There are very few loudspeaker systems of any price that don't make a critical listener accurately unhappy when he or she returns from a live concert to put on a recording. The Maxim is, amazingly, one that doesn't. In fact, of all the speakers in this price class that I have heard. I would say that Siefert's Maxim III is probably the most successful design of all. Mated with a suitable power amplifier, and not pushed too high a listening level, it is one of a small handful of moderately priced speaker systems that can make most audiophiles (and practically all music lovers) quite happy for an indefinite period of time. Recommended."  ~J. Gordon Holt

Paradigm Monitor 11 v4

Paradigm Monitor 11 v4

Paradigm Monitor 11 v4 

(Canada '05-08)  $500

In excellent cosmetic condition, fully tested and in perfect operating condition, this pair of Paradigm Monitor 11 V4 speakers were designed,
engineered, and completely manufactured in Canada.  

Each enclosure has 5 drivers: there are three 6.5" carbon-infused cones, a single 6.5" injection-molded copolymer cone and a single 1" pure titanium dome tweeter.  The heavily braced interiors and elaborate crossover network get all those drivers to pump out some seriously satisfying bottom end combined with no listening fatigue for those delicate high end musical passages and clear vocals.

The Paradigm Monitor Series speakers originally surfaced in 1997 and Paradigm revised them a number of times. This pair of the Monitor 11 V4 are the fourth-generation models featuring upgraded crossover parts and tweeters that Paradigm deployed in their more-expensive Studio Series speakers. The other and more-visible change to the Monitor V4 is a snazzy, brushed-platinum lower base with black ash cabinets and real walnut veneer tops. 

Despite their size, the 45" tall Monitor 11's sonically disappear like a set of mini satellites (or much more-expensive big speakers). Thanks to their unusually high efficiency of over 93 decibels at 1 watt, the Monitor 11's can play seriously clean (and loud if you want) yet you will never detect any amplifier or speaker strain.

During the 80's, it seems that every speaker manufacturer pushed out huge towers as part of a home theater setup.  While that's true, if all you want is stereo then the bottom line is still having one great pair of speakers.  Most times it's just not necessary to have a roomful of speakers to get the sound you're looking for.  We detected no negatives with the Monitor 11 V4 that necessitated a reason to add anything else except a really good amp.  Although they are tall, they have less than an 8" footprint; since the ports are on the front, they can slide into a space only 10" wide and about 16" deep.

Type: Two-and-a-half-way system
Tweeter: single 1" titanium dome
Midrange: single 6.5" injection-molded copolymer cone
Woofers: three 6.5" carbon-infused cones 
Nominal Impedance: 8 ohms
Recommended Amp Power: 50 to 250 watts

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!)




RSL RogerSound Labs CG-6

Compression Guide (1991)   $400

In excellent cosmetic and operating condition, this pair RSL CG6 speakers are rarely seen on the East Coast.   These are a 2-way studio monitor system internally wired with monster cable.  The CG-6 was first introduced in 1991 and was manufactured through an alliance between RSL and Klipsch until 1992. 

The beautiful oak cabinets have RSL's "red line" distinctive grills and unique brass badges; a knuckle rap on the enclosures reveals the very solid, heavily braced construction.  They weigh 20 lbs each. 

If you look at the cutaway view in the photo above you can see how the narrow horizontal front-facing ports allow the CG-6 to pump out an impressive amount of air that eventually winds its way through the interior maze design referred to as the "compression guide" technology.

While no longer in production, CG-6 speakers are still owned and listened to by RSL fans around the world as part of two-channel audio and/or home theater surround sound systems.

Rogers used their proprietary Compression Guide (CG) technology as they recognized that resonance inside a speaker enclosure can create havoc for your ears.  The compression guide system is kind of like a cattle shoot for air within the speakers. Air will travel throughout the speaker enclosure from areas of high compression to areas of low compression in an attempt to prevent internal resonances from mucking up what the woofers and tweeters are trying to accomplish. Rather than just letting the air bounce around inside the cabinet until it’s worn itself out or escaped through the port (in vented styles), CG directs the air along a calculated route. The purpose is to create very clean, accurate sounding speakers.

About RogerSound Labs (RSL)...
In the ‘70s and ‘80s Howard Rodgers owned a series of hi-fi stores in Southern California called Rogersound Labs. He was (and still is) an icon in the San Fernando Valley, CA who had built himself a reputation for manufacturing the highest quality speakers possible for the money. They sold direct to the consumer to avoid high retail markups and put most of the savings back into the quality of their builds. In the 80's, RSL Speakers were industry-standard in many recording studios throughout Southern California. Howard started off in a small shop in North Hollywood, building speakers one at a time by hand. He later moved the business to a larger facility in Canoga Park where he really gave JBL a run for their money.


Polk Audio Monitor 7B 

('79-'84)  $300

In very good cosmetic condition and perfect working condition, these Polk Monitor 7B speakers are considered rare and extremely desirable.  This pair has the rosewood veneer cabinets and Peerless tweeters.

The Monitor 7 family was probably the single most popular entry into serious high fidelity in the mid-Atlantic during the late 70's.They provided a pretty good approximation of the "British monitor" sound (KEF, Rogers, Spendor, Chartwell, etc.) at a fraction of the cost. Smooth, sweet, clean, transparent, and just a pleasure to listen to. "Dollar for dollar there was nothing in their day that would touch 'em" said one guy to the other guy (ha!).

This pair are the earliest version with Peerless tweeters.  The Monitor 7 is considered be best model of the Monitor series of speakers, and the “B” versions of Model 7 is considered the best variant.  Matthew Polk, the Monitor series designer, agrees. This is because the 7B was the last variant to use the superior Peerless tweeter but incorporated other improvements missing in earlier versions. Most listeners prefer the Monitor 7 to the larger and more expensive Monitor 10 and 12.  They originally sold for $480 in 1979!

About Polk Audio (vintage years)...
Polk Audio was founded by Matthew Polk, George Klopfer and Sandy Gross in 1972. Matthew, George and Sandy met each other while attending classes at the John's Hopkins University in Baltimore.  After graduating in 1971, the team collaborated on producing a sound system for a local bluegrass convention. Matthew designed the speaker system while George built the cabinets. After it was discovered the producers of the convention could not afford to pay for the system, George designed a logo for Polk Audio and attached it to the speakers. Sandy was behind the marketing of Polk Audio and also helped create Polk's worldwide dealer network.

After spending a short period of time dabbling in professional audio, Polk Audio turned its attention to high end home audio.  With the release of the first successful model in 1974, the Monitor 7, Polk Audio started to become a recognized name in audiophile circles. Polk used a two way configuration on the vast majority of its speakers like the popular Monitor series (5, 7, 10 and Monitor 12) typically with high performance 6.5" mid/bass drivers with rubber surrounds and passive radiators.  Later Polk speaker models used arrays of drivers, called SDA for Stereo Dimensional Array.  Polk Audio is still in business today.



Q Acoustics 3020

Q Acoustics 3020

Q Acoustics 3020 

(England, '15-'21)  SOLD

In essentially new condition, this pair of amazing Q Acoustics 3020 bookshelf speakers come with the original box, packing materials and documentation.  The modern classic contemporary design, wrapped up in stunning graphite 2-tone grey enclosures with radius corners, immediately gives you a visual of subtle elegance.  Don't let their size fool you, wait until you hear them.

Upon their release in 2015, the Q Acoustics 3020 bookshelf model was the much talked about new hifi speaker.  In comparison with the slightly smaller, earlier, award-winning Q Acoustics 2020i, the 3020 retained Q's high standards in cabinet constructions. The 3020 system benefits from advanced low distortion, wide dispersion, a new 3000 Series 1" concentric ring dome tweeter; updated crossover and improved low resonance cabinet. In addition, it boasts a larger 5" drive unit, with the Aramid fiber/paper cone material.
NOTE: this is a very clever bass driver, made from a mix of paper and aramid fibers that are very similar to the likes of Kevlar and Teflon
This larger driver delivers an extended big bass response with fast dynamics, wonderfully open, realistic midrange and an extraordinary 'being there' three dimensional sound.

Despite their minimalist size, they deliver a wide, deep soundstage populated by nicely layered and precise focus on the vocal and even the musician's instruments.  Most impressive are the dynamics: they deliver the music’s crescendos with confidence, while rendering low-level subtleties with a skill quite outside the scope of most rivals costing twice the price (or more). 

Enclosure type: 2-way reflex,
Mid-bass: 5", Tweeter: 1"

About Q Acoustics...
The company is part of the stable of companies that includes veteran speaker cable manufacturer QED and Goldring phono cartridges. Q Acoustics was set up as a brand by parent company, Armour Home, around 17 years ago to plug a gap in its product line-up. The range of Q Acoustics speakers is the brainchild of Steve Reichert, an audio industry veteran himself, who acts as Q Acoustics’ ‘golden ears’ and works on developing new designs alongside a German speaker engineer based in Essen, and a British industrial designer from Cambridge. The speakers are very much a product of European speaker design which are then manufactured overseas to Q Acoustics’ exacting specifications.

About Klipsch...
He probably wouldn't recognize most of today's products bearing his name but in 1946, Paul W. Klipsch (PWK) changed the face of the audio industry by inventing, discovering, hypothesizing, and proving that it was darn well possible to make and reproduce exciting, explosive, accurate audio. Real, dynamic music was heard in living rooms for the first time – nearly mimicking the power of a live performance. Along the way, PWK worked with industry giants, famous pop stars, and some of the smartest people in the world – always in search of a better sound.

Klipsch was an American audio pioneer, a true eccentric and a proud member of the Engineering and Science Hall of Fame. He gave rise to technologies that would forever impact generations of music lovers. He left an amazing legacy
