Rare Vintage Janszen Model 65 Electrostatic Speakers Hi Fi Tweeters For AR1/KLH

Rare Vintage Janszen Model 65 Electrostatic Speakers Hi Fi Tweeters For AR1/KLH

Tested and, incredibly, appear to work fine!! Could probably use a tear down and restoration but actually sounded decent as is! A pair late of 1950’s — early 1960’s JansZen speakers — electrostic panels, a little known and irresistible cutting edge technology at the peak of HiFi in the late 1950s! So good, they’re owned by many modern day audiophiles where they see use daily. Electrostatic technology, born in these early days of HiFi — hasn’t changend as much as one might think. Still one of the best ways to produce stunningly realistic mids and highs (within limits) — these 1st generation JansZen panels were cleverly and quite ruggedly constructed as modular panels — method you don’t see much these days. These units (when restored and working) are known by many to sound great — both as an add-on — and in the case of Janzen usable stand alone with a woofer! As an acessory they give allot of air and detail to your system. You don’t see these smaller, super neat Model 65’s very much. Intended to upgrade the Acoustic Research Model 1 and AR1W and the early KLH 1960’s and even the original Advent! Pretty much any midsize bookshelf works well with a set of early JansZens like these. With two panels per box they’re the perfect (not overpowering add-on). They’ll make almost any small bookshelf system from this timeframe sound brighter, clearer and overall more realistic. Real hardwood cabinets are a treat! They add both a bit of form and function to any nice mid-century bookshelf — most notably AR and KLH. These Model 65’s were the smaller brother to the larger Model 130. The Model 65’s were rated at 700 c/s all the way to 30,000 c/s! Cool looking 2-element design, space-y, mid century atomic, “googie” look. Very Handsome on top of otherwise plain looking bookshelfs of the era! Made of nice real wood, with handsome chrome plated back covers, hosusing the network filters and power supply. They are great to add to most any 1950s / 60s or 70s era bookshelf. Keep in mind, these Janzens when up and running are some of the finest tweeters (and a bit of midrange) that your could ever add to your existing setup. JansZen was the pioneer in Electrostic speaker design in the USA, leading and refining the earliest designs alongside QUAD of England. Later in the 60s, JansZen contributed the the graoudbreaking Acoustat systems. They have builtin HF crossovers, so just straight wire, bi wire or parallel them right in. A very cool, clean upgrade for your vintage audio setup.

Acoustic Research AR1 W Speaker With Janszen 1-30 Electrostatic Tweeter Matching

Acoustic Research AR1 W Speaker With Janszen 1-30 Electrostatic Tweeter Matching

Incredibly gorgeous and rare Acoustic Research AR1-W Speaker paired with the Janszen 1-30 electrostatic speaker system. The speakers are made of marching rare blonde birchwood, the rarest and most desirable wood option they offered. These speakers both look and sound exceptional. The music they make is unlike anything else. Everything works as it should. No major blemishes or issues on either speaker. Both speakers are untouched or opened, just the way collectors like. It’s rare to find these speakers untouched and in this cosmetic condition that are working like new.

Acoustic Research AR-1W and Janszen 1-30 Electrostatic Tweeter No Reserve

For your consideration is an Acoustic Research AR-1W woofer with a Janszen 1-30 Electrostatic Tweeter. The woofer has been swept and produces perfect output from 20 Hz to about 1000 Hz as expected. I believe this unit has an orange cloth surround. The tweeter is sort of working as is, for now, but could use a recapping. The sensitivity control on the back doesn’t appear to have any effect whatsoever.

Acoustic Research AR-1W woofer and JansZen Model 1-30 electrostatic tweeter

This is a vintage set-up. Acoustic Research AR-1W woofer and JansZen Model 1-30 electrostatic transducer. Both tested, fully functional. The cabinets are in good to very good condition. The Model AR-1 was unveiled at the September, 1954, New York Audio Fair. It consisted of a 12-inch woofer designed and built by AR. High frequencies were handled by the 755A, an 8-inch full range driver of Western Electric design, produced by Altec. Both units were in a sealed 3/4-inch thick plywood cabinet filled with fiberglass. The size was just under two cubic feet with dimensions of 25″ x 14″ x 11, noticeably smaller than other high performance loudspeakers. It weighed in at about 50 lbs. A Model AR-1W (a woofer only speaker), shown in Figure 1, was also produced and was intended to be used with a separate high frequency unit such as the Janszen Model 130 electrostatic tweeter. Most impressive was the fact that the Models AR-1 and AR-1W could reproduce frequencies down to 32 cycles per second with very low distortion, something the large mechanical suspension speakers could not do. Among the features of AR woofers built through the late 1960s were a cast aluminum speaker frame, an Alnico magnet, and a treated cloth cone surround for a free suspension. Kloss was put in charge of the AR factory and is credited with 75 percent of the Model AR-1’s production design. Julian Hirsch, who at the time published the Audio League Report, wrote, The AR-1 & AR-1W have established a new industry standard for low distortion bass. The item “Acoustic Research AR-1W woofer and JansZen Model 1-30 electrostatic tweeter” is in sale since Wednesday, June 13, 2018. This item is in the category “Consumer Electronics\Vintage Electronics\Vintage Audio & Video\Vintage Speakers”. The seller is “musicsol” and is located in Bolingbrook, Illinois.

Acoustic Research AR-1W Speaker with Janszen Model 1-30 Electrostatic Tweeter

If you are looking for this speaker and/or tweeter, odds are you know how special and rare these are. However, in case you don’t know much about these vintage marvels, here’s a little information. The Model AR-1 was unveiled at the September, 1954, New York Audio Fair. It consisted of a 12-inch woofer designed and built by AR. High frequencies were handled by the 755A, an 8-inch full range driver of Western Electric design, produced by Altec. Both units were in a sealed. /4-inch thick plywood cabinet filled with fiberglass. The size was just under two cubic feet with dimensions of 25″ x 14″ x 11, noticeably smaller than other high performance loudspeakers. It weighed in at about 50 lbs. A Model AR-1W (a woofer only speaker) was also produced and was intended to be used with a separate high frequency unit such as the Janszen Model 1-30 electrostatic tweeter. Most impressive was the fact that the Models AR-1 and AR-1W could reproduce frequencies down to 32 cycles per second with very low distortion, something the large mechanical suspension speakers could not do. Among the features of AR woofers built through the late 1960s were a cast aluminum speaker frame, an Alnico magnet, and a treated cloth cone surround for a free suspension. The woofer has an amazing 1.4 inch or so travel and produces really low distortion fundamental frequencies down as low as 20 Hz about 6 db down. This will outperform the vast bulk of the subwoofers made today and runs just fine on a 60W amplifier. This speaker and tweeter work great and produce gorgeous sound. Janszen Model 1-30 – SN 5676 – 7″ H – 23″ W – 9 D. AR-1W – SN 9703 – 14″ H – 25″ W – 11.5 D. The information contained herein is what I have gathered from reputable sources online and from speaking with audiophiles and experts in this field. Feel free to ask questions. I will answer them to the best of my ability. The item “Acoustic Research AR-1W Speaker with Janszen Model 1-30 Electrostatic Tweeter” is in sale since Monday, August 29, 2016.
