Pair Connectors Tweeter Terminals Posts AR-2A AR-3 speakers Acoustic Research

This is a rare and historic AR-3 Acoustic Research speaker from the First Edition collection of 1967. It has a power output of 100W with an impedance of 4 Ohms, making it ideal for any sound system. The brand speaks for itself with its exceptional quality and performance. It's a must-have for any collector or audiophile who appreciates vintage audio equipment. Original 1967 cloth surrounds woofer Big magnet first edition rare Tweeters ok fully working Mid range not working ,need fixing Very rare items unknown in the UK, items were collected from a hifi top end collector who had a very expensive Thorens turntable and an amazing Sansui quadraphonic amplifier .All original bought in the sixties. Cabinets in very good condition ,Thick walls all made in USA . 25 kg each Att. No profesional speaker repair sites in the UK No one can repair tweeters or mids or woofers just replace the surrounds those “professionals? My A ..s I’ll send them to speaker fix in Belgium if I got time. and Specs No loudspeaker by Acoustic Research has been more influential than the original Acoustic Research AR-3 acoustic suspension speaker. The AR-1 had set a new benchmark for loudspeaker technology, but the AR-3 was so outstandingly accurate that experts had trouble identifying whether a recording or a live concert was playing in front of them. Let´s note here, that this is not the AR-3a speaker from 1967, but its prior version from 1958. The AR-3 speaker had been designed by Edgar Villchur, whereas the newer AR-3a speaker was designed by Roy Allison. Even though both speakers are fairly similar, the AR-3 has been a landmark for the loudspeaker industry and had been recognized by the public significantly more than the later AR-3. History of the AR-3 he AR-3 entered the market in 1958, 4 years after the first ever acoustic suspension loudspeaker, the AR-1 was introduced. Acoustic Research had by then tested a new tweeter design, developed by Villchur, called the hemispherical dome direct radiator tweeter, which was used in the new AR-3 models. Besides the newly invented dome tweeter, Villchur´s loudspeaker also received the AR-1s woofer from 1954, which had been another speaker technology landmark, as it was the first ever commercial acoustic suspension speaker. The result was a speaker that produced music more accurately than any other speaker at its time and is until today one of the highest performing speakers available when measuring accuracy. This outstanding accuracy made the AR-3 speaker famous, and its reputation for being the “most accurate loudspeaker at any cost” led to its usage in many professional settings, such as concert halls or record studios. Acoustic Research Concerts The reputation for unmet accuracy was underlined by a series of concerts during the 1960ies in which Acoustic Research directly compared a live string quartet with a recorded version of the same music played by the AR-3. Listeners were unable to detect the switch overs between recorded and live music, which supported the already established reputation of this loudspeaker and leaves a great impression as to how accurate this speaker has been. Even after the “improved” version of the AR-3, the newer AR-3a model was introduced to the market in the mid 60ies, Acoustic Research continued to manufacture the original AR-3, by then over 10 years old, until the 1970ies. AR-3 and AR-3a Specs and Comparison During the period in which both speakers, the AR-3 and the AR-3a, were available some alternations had been made to the AR-3 model, being more and more similar to the newer AR-3a. Some changes, as well as parts that did not change are listed below: Originally the grille cloth of the AR-3 was different from the AR-3a, but changed in the later half of the 1960ies (approx. 1967) and became identical to the one of the AR-3a. Early AR-3a had the cloth-surround alnico magnet woofers identical to the AR-3, which were already used in the AR-1. Later the AR-3, as well as the AR-3a were equipped with foam-surround ceramic magnet woofers. Crossovers of AR-3 and AR-3a are different: Mid / Tweeter: 1000 / 7500 Hz vs. 575 / 5000 Hz. The lower midrange of the AR-3a was better for dispersion. Overall it can be said that maintaining the original Acoustic Research AR-3 is more difficult than the newer AR-3a. Parts are not as easy to find and less AR-3s are on the market in general. However, a AR-3 restoration project is a well doable thing and many guides are available online to do so correctly. *Taken from :Vintage -Speaker review.com Toby 2020

Acoustic Research, Inc. (AR) 1-1/2 Dome, 4-ohm, AR-3a Midrange, #200010-1, Inoperative, for Repair. This AR-3a midrange 1-1/2-inch dome driver is inoperative and not working. This unit was a factory demonstrator for instructional purposes. The voice coil on this AR driver is likely intact, but no specific test has been made because there are no lead-out wires. Also, the domes suspension is not intact. This midrange driver had an inverse half-round suspension to center the dome, and that portion has been removed and would require a similar piece to center the dome. The dome does have the proper fiberglass under the dome and the small pad to go between the screen and the top of the dome for damping. Properly working, this dome midrange driver is one of the finest midrange drivers ever designed. This midrange dome driver, dating from 1968, was designed Roy Allison and Charles McShane of Acoustic Research, to be used in the AR-3a and later the AR-LST. The driver is a 1-1/2-inch butyl-rubber treated linen solf-dome diaphragm and provided extremely uniform, accurate sound reproduction and dispersion within its pass band. The magnet assembly is ferrite and approximately 6 lbs. Note that this tweeter will be shipped with a protective cup covering the dome to prevent shipping damage. Ref. AR-2301890
