Boston A-70

Boston A-70 (1980) $160/pr 

From the original brochure:
"The slim profile of the A70 not only makes it easier for you to place the speaker unobtrusively in a room; more important from a music lover's point of view, the dimensions of the cabinet minimize unwanted sounds that would ordinarily muddy the stereo picture.  The A70 has a remarkably wide dispersion for a 2-way speaker, which permits the imaging to be stable over a wide listening area. Boston beveled the grille panel around its inner perimeter to minimize early reflections that can blur the stereo image.  As a result, a cabinet of about one cubic foot (28 liters) internal volume was chosen as the most cost-effective solution, with an aspect ratio of front panel size to cabinet depth that research (at the time) by Boston Acoustics indicated would yield the optimum imaging capability."

Realistic Optimus 27

Realistic Optimus 27 (1980-1983) $125/pr

Realistic came out with this unique passive radiator system (rated at 8 ohms) to "provide low distortion and transparent sound quality.  High frequency dispersion is accomplished through a carefully designed phase-correction assembly" this was to prevent "beaming" for uniform, open, airy natural sounding fidelity so "no matter where you sit, you hear all the music." Probably the most striking part of this design are the slim-line, minimum refraction cabinets - genuine walnut veneer on slim, sloped trapezoid shaped enclosures that can easily sit on the floor, backs to the wall and fit into any room setting......this 3-way system features 1" textile soft dome tweeters, 6.5 active low frequency drivers and 8" high compliance passive radiators tuned to the main driver....

About Realistic/Optimus/Radio Shack/Tandy Corp...

Realistic branded vintage stereo gear is all over the place.  Some of it is right up there in quality with the best of Pioneer, Sansui, etc.  Also, some of it is just...ok.   Their best era was during the 70's when they successfully competed head-to-head with all the big names in high fidelity.  They sourced practically all their products from Japan and sometimes had the exact same components inside their gear as the competition but at a much lower price.

RSL Magnificent

RSL Magnificent (1989) $140/pr

Designed as a bookshelf speaker that can outperform most floor sized units, these beautiful and very heavy solid oak cabinets have a 2-way system with a 2nd order crossover.  Becoming rare (as are a lot of RogerSound Labs vintage speakers), the Magnificents are some of our favorite speaker systems.  We've had several pair before and once you see them and hear them...you'll want them!



RSL (RogerSound Labs) Outsiders 
(1982)   $99/pr 


In 1982, if you wanted music outside your home you had 2 choices: 1) You could purchase tinny-sounding metal horns. 2) You could turn your up your stereo inside and open some windows and doors. It was then that RSL introduced the Outsiders, the world’s first high fidelity outdoor speaker. It’s now 30 years later and many of the original Outsiders (including ours!) are still going strong, even if some of us aren’t.


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.

Jennings Research Contrara Group Pedestals

Jennings Research Contrara Pedestals (1976) $300


~rare~rare~rare~
Jennings Research was based in Los Angeles, California, USA and founded in March, 1975 by Tom Jennings.  Mr Jennings had been the head of marketing for JBL in the late 60’s, early 70’s and was instrumental in the success of the JBL Aquarius series. In a different time he was also CEO of Wald Sound.  As it is with most driven entrepreneurs, Jennings stuck out on his own, brought in a dedicated group of talented associates and made some amazing speakers. 


The initial product line at Jennings Research was called the “Contrara Group”.  At the top of the line was the "Contrara Elan Pedestal" with twin Audax tweeters and Audax woofers.  Next up was the "Contrara Group Pedestal", which features twin woofers and a single tweeter.  Also included in the model series were the "Contrara Group MKii Rectangles" which had single woofers and tweeters in each cabinet. 

Other than the high quality drivers and crossover networks, the most striking thing is their physical appearance: all the Contrara Group pedestal systems feature hand-rubbed, solid dark walnut cabinets with mosaic tops.  The Rectangles have the same high quality finish but without the mosaic tops.  The pedestal models also have very heavy cabinets mounted on swivel bases which is quite unique, to say the least.  There were a few other speaker models, not as well known but still carrying the Jennings Research badges.


They were introduced in the summer of 1975 and the company initially made quite a splash with an advertising campaign in national magazines such as "Popular Science" and the "New Yorker Magazine". The well-designed systems sold well, but, unfortunately, the very high cost of materials and labor, let alone the cost of marketing and sales, put Jennings Research in a precarious position compared to the well-funded competition. 
There was no question the product is excellent but, as happened to so many companies in the crowded high fidelity market, they just couldn't stay afloat.

Occasionally,  Jennings Research speakers turn up for sale but are considered very rare because, generally speaking, they sound VERY good and most audiophiles tend to consider these "keepers".  The company also introduced a line of amplifiers the next year, but they appear to have only been in production for only a couple of years.

BIC Venturi v62 (1989) $125
ADC Sound~Image 5004 (1992) $140
M&K Satellite (shown with Realistic subwoofer)

M & K Satellite 1 (Miller & Kreisel, 1977) $325
(includes Realistic 40-4050 subwoofer from 1993 see photo)

Thanks to Steely Dan, the famous and high end M&K Satellite speaker system was born!
In 1977, M&K designed the original Satellite-1, a speaker system with a unique design goal: controlled vertical dispersion. Unique to the S-1 was the adjustable spectral balance (now known as timbre-matching) that was an integral part of the sound and was clearly explained in the setup instruction sheets (included).  It wasn't until 1978 until they released the consumer audio version of Kreisel’s innovative world-class professional studio monitor speaker system design called the Satellite-Volkswoofer System. This system was originally designed by Kreisel for his own use in the M&K RealTime Direct-to-Disc recording studio. Incorporating controlled vertical directivity, a phase-focused crossover with true driver group-delay time alignment, dual-midrange and tweeter driver arrays and minimal baffle coloration, this system made for one of the most dramatic and revealing listening experiences imaginable.  Stunning in design and shape, the stacked components are as much beautiful woodwork sculpture as they are a magnificent sound experience.

In the beginning, M&K's basic design goals for stand-alone satellite speakers (*with or without subwoofers) remains today, as always, a noble assembly of values:  Low Distortion, Flat Frequency Response (across a wide window), decent Transient Response, and healthy Dynamic Range. 


About M&K (Miller and Kreisel)...

In 1969, Ken Kreisel is a teenage audiophile and audiophile recording engineer. Kreisel teams up with Jonas Miller who has opened one of the world’s first ultra-high-end audio salons: Jonas Miller Sound of Beverly Hills, California.  In 1973, Ken Kreisel designs and installs for Walter Becker (of "Steely Dan") the first M&K Subwoofer and triamped studio monitor system for the studio mixdown of Steely Dan's "Pretzel Logic" album. The subwoofers used specially designed long-throw dual 12” drivers mounted in a unique balanced drive configuration.  In 1974, Ken Kreisel and Jonas Miller launch Miller & Kreisel Sound (M&K) founded in Beverly Hills, CA. Contrary to popular rumors, M&K started its subwoofer & speaker production in the prestigious high rent district of Beverly Hills on Wilshire Blvd., not Ken’s garage.  In 1976, again making audio history, Kreisel invents the modern day "Satellite-Subwoofer" system, The "David and Goliath" System.  Shortly therefater, Kreisel and M&K debuts the world’s first Self-Powered Subwoofer! This model was called the Servo Volkswoofer. This idea revolutionized the entire audio industry.  From then on, the innovations and awards kept coming...

Optonica SA-5406
Klipsch Reference Series RSX-3 (1995) $175
a/d/s L520

ADS L520 (1982) $250

ADS produces some of the best two-way bookshelf speaker systems that money can buy and the premium L520 is certainly recognized for their excellence.  A quick check online will yield reviews by just about everybody that has experienced their sound.
Their unique one inch acoustic suspension soft-dome tweeters account for the ultra-clean, "airy" high-frequency response.   The tweeter dome is a super-light fabric-like material with a proprietary "sticky" damping compound and a powerful Barium Ferrite magnet (there's a lot more to describe but suffice to say, the ADS tweeters are fantastic!)The L520 has 8-inch woofers featuring ADS' tapered "Stifflite" cones. (Stifflite is a relatively thick material formed of air-filled, randomly-oriented pulp fiber in a unique "sandwich" construction).  Because of this unique design, ADS firmly believes it has the closest thing yet to the ideal woofer cone.  
The network crossover components, furthermore, are of the finest quality. Thanks to ADS' advanced driver technology, ADS' crossover networks are free of excessive complexity and have the lowest power loss and distortion figures in the industry. 
Finally, the walnut veneer enclosures are precision constructed from 3/4-inch extra-high density particle board with extreme bracing.  We have upgraded these with NOS vintage burlap linen grills with the original ADS logo badges.
Good stuff! (photo below shows L520 with grills removed)

a/d/s L300C Mini Monitors
(1991) $125 (photo below)

These "little" guys are about 60% smaller than the L470/2, but seem to pack almost as much punch in the bottom end.  These are keepers, very easy on the ear.  Smooth and detailed.  Rare.


About a/d/s (Analog & Digital Systems)...
Manufactured since the early 80's in Germany (Braun) and the USA, a/d/s products are very high quality and have a very detailed sound...highly respected speaker systems.  Audiophile sonics.

Epicure Model 70C

Epi Model 70C (Epicure, '77-'79)  $125

These have the inverted dome tweeters as the 2-way "C" model was a later version but basically the same as the original Model 70.  Famous name, famous sound, lots of history, the Epicure brand has been around a long time.


About Epicure (Epi)...

EPI was founded in 1970 by Winslow Burhoe, to manufacture speakers based on the "module" he had designed. This module consisted of an eight inch woofer and a one inch tweeter. Many different speakers were built using various combinations of this module, and a six inch version of the woofer. They were wonderful speakers and are still usually prized by their owners, who will frequently go to great lengths to repair them properly when they (rarely) develop problems.

Sansui SP-2500

Sansui SP-2500 (early 70's) $225


Introduced between middle of 1960 and 1974, these SP-2500s (and most all of the SP-xxxx series) are the most well built Sansui speakers of that vintage era.  With their famous "Mikuni" grills and reputation, these are regarded by many as the best model of this range from Sansui.
The SP-2500 is a 3 way system with each cabinet containing one 12" woofer, twin 5" mids and twin horn tweeters.  As you can see from the photo, we always open up the crossovers (on higher end units) to check the caps and clean(deoxit) the attenuators.  After driving these with a 75 watts per channel receiver, they perform flawlessly and are in great sonic condition.  
At a heavy 50 lbs each, the dark walnut cabinets were not perfect so we spent hours restoring and refinishing them to the best possible condition.  
As some of you may already know, Sansui invented the design of the famous "Mikuni" grills.  These grills were all individually hand-made (in Japan) and many companies copied the idea with their own different styles of lattice grills with fabric backing.


About Sansui...
Founded in Tokyo in 1947, Sansui initially manufactured electronic parts.  By the 1960s, they had developed a reputation for making serious audio components. They were sold in foreign markets through that and the next decade.  Sansui's amplifiers, receivers, speakers turntables and tuners from the late 60's, through the 70's and very early 80's continue to remain in high demand by audio enthusiasts.
