Infinty CS-3007 Crescendo

Infinity CS-3007 Crescendo (1993)  $250/pr

Upgraded and beautifully restored...

First off, the exquisite, well-braced, heavy oak enclosures weigh about 50 lbs each, 36" tall and are in excellent condition. 

The original main drivers had basically disintegrated, so, after retaining the Emit tweeters in place...into surgery they went.

The cabinets now contain:

~The original and genuine EMIT-R (902-6759) tweeters*

~Upgraded new, full-range 5" poly mica midrange drivers (1" aluminum voice coils, 12oz magnets, poly mica cones with rolled foam surrounds) 

~Four NOS 8" Audax (France AP210Z0) shielded Aerogel midbass drivers with butyl surrounds (each @ 70 watts RMS, 100 watts max)

~All new beige burlap linen grill cloth material

On the rear: bass ports and bi-amp banana speaker jacks.

*About those EMIT tweeters: 

At 4,000 Hz the second crossover is to an electromagnetic induction tweeter, or EMIT, which employs a planar plastic diaphragm, with extremely low mass, on which a rectangular pattern of conductors is deposited. The diaphragm is mounted in a powerful magnetic field generated by samarium cobalt magnets. It radiates sound through four vertical slits in a metal plate.

About Infinty...

Arnie Nudell, John Ulrick and Cary Christie founded Infinity in 1968. Their first product was the Servo-Static speaker system which had electrostatic panels and a servo-controlled woofer.
Infinity has produced both home and car audio products and they are known for their use of neodymium magnets, mylar diaphragms, and polypropylene speaker cones. Infinity produced the *EMIT tweeter and EMIM midrange drivers and later the EMIT-R, S-EMIT, and the L-EMIM which worked to move air based on the principle of electromagnetic induction. 
The IRS (Infinity Reference System) which cost $65,000 in the 1980s is one of the first ultra-high end speakers systems ever sold. The IRS had 76 EMIT tweeters, 24 EMIM midrange drivers, and twelve 12-inch poly woofers in four tower speakers cabinets.
The Reference, and later Kappa series, were discontinued after Nudell sold the Infinity brand to Harman Kardon. Nudell later formed  high-end loudspeaker company Genesis Technologies,. Genesis' flagship speakers system, the 1.2, sold for US$235,000.  It was for the most part an updated version Infinity IRS Speaker System. 
In the 1990s and beyond Infinity speakers have been less expensive and more mass marketed to the general consumer. The popular SM (Studio Monitor) series speakers had polycell tweeters and graphite impregnated midranges and woofers. 


Realistic Nova 8B

Realistic Nova 8B (1976)  $140/pr

The Realistic Nova 8B speakers do sound just great and were often overlooked because they came from Radio Shack.

Specs are accurate when they claim 20-20,000 Hz, seriously deep bass...

"Realistic" branded electronics at Radio Shack were as good as (sometimes better than) a lot of the competitors' much higher priced models while being essentially the same design as the well known brands of the time. 
Built in Japan for Radio Shack in 1976, each of the heavy, oil rubbed walnut veneer cabinets have 12" woofers (that yield some deep bass), one extended range high-compliance tweeter and two mid-range speakers.  The original crossovers are working fine although some prefer to modify them.  

Variable mid-range and hi-frequency controls are on the rear for personal fine tune tweaking.

The original faux wood lattice grills are perfect.

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.

AR 18S

Acoustic Research AR-18S  (Teledyne era, '81-'85)  $115/pr

Probably AR’s most famous loudspeaker design (insert debate here), the AR 18S are one of those timeless designs that seemingly constantly increase it’s capabilities as technology from the opposite end of the listening/monitoring system improves.  As digital streaming music improves in consistent delivery, the AR 18S handle that perfectly.  Considering that these (and all speakers from the "Golden Age of HiFi ") were designed with analog technology, that's an amazing statement!

This pair is the *newer version with earlier 8" AR-18 poly-infused paper woofers (upgraded 5mf caps) and 1.25” cone type tweeters.  They are two-way stand mount loudspeakers (bookshelf design in old school language). 

The AR-18S are acoustic suspension / sealed box design (another proprietary development of **Edgar Villchur, the founder of the original Acoustic Research Company) and is of good proportions to promote rigidity.  And yes, all speakers prior to the AR model One from the mid 50's were other than sealed enclosure designs!

These AR18’s have some of the most neutral and engaging upper bass / lower midrange spectrum encountered in other well bred monitors of comparable size.  
As usual with most high quality monitors, placement can be critical but once that decision is made, and the AR 18S are connected to a great amp/receiver, they will deliver some truly outstanding sonic happiness.

The dark walnut veneer enclosures and dark brown fabric grills are in excellent condition as well.

Here's a link to a great review of the AR 18:


There were are two different varieties of the 18S.  The newer version is 1.5" wider with terminal cups instead of standard spring strips and the plastic woofer ring is outbound instead of recessed like the original.

About Acoustic Research / **Edward Villchur...

Not long ago, reproducing music at home was arcane and expensive. Edgar Villchur changed that when he formed Acoustic Research, the audio company he co-founded in 1954...high fidelity met affordability.  Most loudspeakers now use one or both of Villchur's innovations — the acoustic suspension design for low-frequency notes and dome tweeters for high notes.  

And something most people never knew about Edward, the principles he discovered for improving hearing aids are still standard.  

At its peak, Acoustic Research captured more home loudspeaker business than its many rivals.  

Villchur moved to New York's Greenwich Village after World War II and parlayed his military electronics experience toward opening a radio repair shop and creating a job teaching sound reproduction at NYU.  As a music lover, Villchur didn't like the loudspeakers of his day, especially regarding the distortion created in lower-frequency notes.  

"Woofer suspensions," wrote former AR executive Roy Allison, "had been made stiff enough so that the woofer could be used in so-called infinite baffles, or other large enclosures, without being torn apart by large, low-frequency power inputs. This mechanical restoring force generated large amounts of distortion when the woofers were driven hard."

Villchur's solution: a sealed enclosure that used the air trapped within to serve as an elastic cushion that became an integral part of the speaker mechanism.  He called it acoustic suspension.  The rest is well known history....



Bose 401

Bose 401 ('88-'94)  SOLD

This is an attractive pair of Bose 401s with walnut vinyl veneer and custom smoked glass tops.  

Each of the 30" tall angled enclosures have twin 6.5" woofers and one 2" tweeter.  

As with most of the Bose speakers, these are 8 ohms, very efficient and can be driven with as little as 10 watts but can handle up to 200 watts.

One side of the enclosures fire outward, the other fires inward.  

With both placed properly, the sound seems to be coming from everywhere as opposed to most speakers that fire forward...typical unique Bose design.

The large bass port on the rear yields some pretty impressive bottom end.

Bose 301 Series II

Bose 301 Series II ('83-'91)  $145/pr

The Bose 301 Series II, with their handsome two-tone light/dark brown grills and walnut veneer over timber cabinets, are generally considered to be the "best" of the many different 301 models developed by Bose over the last 40+ years.

This particular pair is in excellent cosmetic and working condition.  

With the right placement, they will suit most of those familiar with the "direct/reflect" purposed design of the Bose 301s.  The best suggested placement of these in the listening room is in the middle, between the L/R side walls to take advantage of the rear firing tweeters.

The "spatial illusion" of sound comes from the unique placement of the twin 3" high sensitivity tweeters in each enclosure (with one facing forward and one facing back) and the 8" woofers facing straight ahead.   

These have a nominal impedance of 8 ohms with a rated 89 dB sensitivity.

As with almost of all of the Bose bookshelf sized models, these are very efficient and don't require a lot of power to do what they were designed to do.

About Bose...
There's nothing we can say that hasn't already been said before about Bose.  You either like them or you don't.  Bear in mind, that in the last 50 years, nobody, and we mean nobody, has sold more speakers worldwide than Bose.  End of story.



Paradigm Mini Monitor V1

Paradigm Mini Monitor V1 (1998)  $135/pr

The Paradigm Mini Monitor V1 system is part of the "Classic Collection" from Paradigm.

These are a 2-driver, 2-way bass reflex design with Quasi-3rd order resistive rear firing ports.  They can be placed on a bookshelf or stand-mounted.  

These are an 8 ohm system with power handling between 15-100 watts.

The crossover is a 3rd order electro-acoustic at 1.8 kHz.  

Each heavy, well braced, dark cherry-wood veneer cabinet has a single 1" PTD pure titanium dome high frequency driver (tweeter) with ferro-fluid damped cooling and one 6.5" diecast chassis, ICP™ injection - molded co-polymer polypropylene mid/bass frequency cone driver, (Apical™).

All we can say is they are stunning sonically and visually.

Reviews from the web:

"Sound quality was excellent with the Paradigm Mini Monitor V1: Its basic neutrality served all manner of music very well, not to mention soundtracks...we can't think of a system from any other manufacturer that provides substantially better performance that doesn't also cost considerably more. Paradigm has done it again!"  ~Stereo Review magazine

"The Paradigm Mini Monitor V1 is perfect for the real-world audiophile on a budget... We've heard highly regarded $2,000 two-way 6-inchers that could not keep up with the Mini Monitor... the Mini Monitor's high end is... the kind of hyper-clean, smooth-as-silk treble we expect to hear from expensive monitors, not budget boxes... the Paradigm Mini Monitor carries our strong recommendation."   ~Audio magazine

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!)


NHT Zero

NHT Zero (1994) $50/pr

These amazing (tiny) compact monitors sound surprisingly spacious, with true-to-life sound reproduction and imaging.  The Zero was called “...not just great for the money, but great period.”, and hailed as “a $250 speaker that compares with high-end speakers costing $3000…” (by Corey Greenberg in the January 1994 issue of Stereophile), the Zero established NHT as a force in the world of high-value, high-performance audio.  Piano gloss black cabinets.  

About NHT (Now Hear This)
NHT Loudspeakers (Now Hear This 1986-2009) The original NHT was a speaker and audio component company founded by Chris Byrne and Ken Kantor in December 1986. Byrne primarily handled sales and marketing, while Kantor was responsible for design and engineering. NHT shipped its first product, the Model 1 loudspeaker, in 1987.  After the release of the now famous "SuperZero" in 1994, the company really took off.  However, as is typical with so many great audio companies, in February, 2009, NHT announced they were "going quiet".




XAM 5E (1968) SOLD

These rare XAM 5E speakers were manufactured by Electro-Voice and sold as a private label model by *EJ Korvette's chain stores back in the late 60's and early 70's.  

The real walnut cabinets contain 8" full range 8 ohm, whizzer cones that, running as a pair, sound pretty darn good (considering they are EV drivers, that shouldn't surprise anyone).  

Fairly heavy, the cabinets do have some battle scars but the vintage linen cloth grills are intact and look real nice...real vintage stuff!  

About XAM...

*EJ Korvette' s, (also known as Korvette's), was an American department store chain founded in 1948.  Similar to Costco because they had membership cards that got you "big" discounts.  Now defunct, they went so far as to market its own "XAM" brand of speakers (made by Electro-Voice) and stereo receivers / amplifiers (some manufactured by EV, Fisher and Roland Electronics of Japan).  XAM was rumored to be a tribute to the owner's deceased dog, Max (Xam spelled backwards).



Criterion 77 by Lafayette

Criterion 77 by Lafayette (1977) $65/pr

These are a nice, restored and refinished pair of Criterion 3-way speakers.  Unlike the "West Coast" boom-boom rock n' roll sound, these are closer to the "East Coast" sound that favors accuracy over thumping bass (think jazz, classical, etc).  Of course, the vintage grill material on these are nearly impossible to duplicate so that adds to the "flavor" of that vintage look and feel.

About Lafayette...

Established in the 1920s, Lafayette Radio Electronics (LRE) became a thriving mail order catalogue business; the electronic components it sold were useful to amateur radio operators and electronic hobbyists in areas where such components were unavailable in local retail outlets. 
Early Lafayette Radio stores were located in New York during the mid '50s. 

Lafayette advertised heavily in major U.S. consumer electronics magazines of the '60s and '70s, particularly.  The company offered a free 400-page catalog filled with descriptions of vast quantities of electronic gear, including microphones, speakers, tape recorders, and other components.
A significant share of '60s and '70s vintage Lafayette hi-fi gear was manufactured by a Japanese subcontractor named "Planet Research". "
The Criterion" brand speakers were built by several offshore and American assemblers.
