Acoustic Research AR 90 pair floor speakers 4 way 5 Driver Professionally Tested. These are in incredible condition. I had them professionally tested by someone who deals in vintage electronics and speakers. Everything is original accept I had them refoamed due to age. All screens are in excellent condition. Both speakers have been cleaned and checked over thoroughly for any flaws and for completeness. The only thing is a small spot on the top of one speaker where the finish has partly come off, not a water stain and could be easily fixed. The number on speakers are 007886 and 007898. This is definitely not your average listing and a very rare find for the condition they are in. Really amazing collectors set.

Teledyne Acoustic Research AR14 Speakers, Professionally Restored!! Speakers cabinets beautifully refinished (not perfect but close), crossovers tested, surrounds replaced. And re-foamed. These speakers sound gorgeous, and are near mint. It is my sincerest experience though that as long as the piece is in good condition, properly serviced/repaired, and of course WELL PACKED, issues if any are very minor. Their knowledge and experience is indispensable and often they have an abundance of used parts on hand to perform relatively inexpensive repairs. This item is in the category “Consumer Electronics\Vintage Electronics\Vintage Audio & Video\Vintage Speakers”. The seller is “jonandbear” and is located in this country: CA. This item can be shipped to Canada, United States.

For sale: Custom Professionally built 3-way speakers using Acoustic Research AR-3a cabinets. The only things AR-3a about these speakers are the cabinets and the woofers. Professionally built by Audio Ventures of Waukesha, WI, these speakers belonged to my uncle who was a professional violist in a large city symphony orchestra. The cabinets have original AR-3a serial numbers 3A02215 & 3A02228. Both speakers feature the following components. AR 12 Woofer, Model S21297 (also has L21TNB stamped on magnet) with paper cone, foam edge suspension and 5½ diameter magnet (foam edge suspensions have recently been replaced on both woofers). VIFA (Denmark) 5½ diameter 8 ohm Dome Midrange, Model P13WH-00 with 3½ diameter magnet. VIFA (Denmark) 1 diameter 6 ohm Dome Tweeter, Model D26TG-35 with five (5) 4.0u F100V capacitors and two (2) resistors (a Colber 3.5 ohm 5% CWID and a 10w 5 ohmJ). All components are in excellent condition. Technical information about the crossovers is unknown. The cabinets are in very good, very solid and original bare/unfinished condition (they do have a few age-related minor nicks and scrapes). Both cabinets have the original AR Guarantee Information and Inspection Card, as well as the Original Serial Number and Instructions for Use paper/label attached to the backall in good condition (3A02228s S/N and Use Paper is in fair condition with a portion missing). Both grills are the original AR-3a grills and are in good condition but do not have the original AR-3a logo plates attached. These speakers sound amazing, and the base is simply awesome.

We are pleased to offer for sale an extremely rare, matched pair of the legendary Acoustic Research AR-3 Speakers with the original unfinished pine cabinets and maple grill surrounds. Unfinished pine veneer was one of the original finish options offered by Acoustic Research. As an added bonus, these fully restored speakers boast the original black plastic grill frames, the original AR-3 vinyl grill fabric and the original AR. Actually, the only parts that are not original to this pair of speakers are the Cerwin Vega12TR 15T CV 12-TR Control Potentiometer Pots that were professionally installed to replace the failed, original pots. This is a must have pair of speakers for the serious audiophile and /or the serious vintage collector. These AR-3s are considered a matched pair based on the consecutive odd number serial numbers C 25263 and C 25265. According to Acoustic Researchs serial number identification information, this pair of speakers was manufactured ca. 1968 and are considered Gen 3. Generation 3 speakers were produced from August 1965 through May 1970and include serial numbers C 19468 through C 70228. In May of 1970, Acoustic Research ran out of the original phenolic-dome mid-range drivers which then required the use of a version of the AR-3a mid-range drivers. So these Gen 3 AR-3s are the last generation to still use the original phenolic-dome mid-range drivers. This matched pair of speakers is in excellent original vintage condition and the original Guarantee and. Instructions For Use labels are fully intact (and protected) on the backs of the cabinets. The maple front, pine veneer plywood cabinets are in original condition and still exhibit the sanding marks and wood-putty fill as they came from the factory. The original vinyl grill fabric has yellowed with age but is otherwise in great vintage condition. When we acquired these speakers we noted that one of the original black plastic grill frames was broken in two places along the top edge. This part of the grill frame is notoriously fragile so we repaired the break with a 2-part epoxy glue and added an 1/8 maple plywood splint along the top edge to strengthen the frame and minimize any future damage should the grills require removal in the future. As the grill frames required removal in order to replace the potentiometers, we added the same 1/8 maple plywood splint to the top edge of the second speaker grill frame as well. Both speaker grill frames are slightly bowed in towards the centers at the top and bottom and we elected to leave this condition alone rather than risk damage to the grill frames and fabric by trying to remove and re-attach the vinyl grill fabric. We suspect this defect is a result of the vinyl grill fabric shrinking over time and bending the rather flexible plastic frame. We had this pair of AR-3s tested professionally and all systems were functioning perfectly with the exception of the original potentiometers. Hoping to keep this pair of speakers in all original condition, we had the original potentiometers removed and cleaned but they failed the testing process so we had them replaced with the modern wire-wound potentiometer as described above. The new potentiometers are an exact copy of the original (in terms of values 16Ohm / 25Watt), but much better in terms of reliability and quality. The original failed potentiometers will be included in the sale. The entire restoration process has been exhaustively documented with photographs which are available upon request. We also have a stereo audio recording of the restored speakers available upon request. SIGNATURE AND LABEL INFORMATION. Both labels on both of these speakers are fully intact and are currently protected from wear with clear plastic attached with painters tape, which can be easily removed if desired. Each speaker cabinet measures 25 in height, 14 in width and 11.5 in depth. Each speaker cabinet weighs approximately 55 pounds. The item “Acoustic Research AR-3 Speakers. Professionally Restored, Rare Matched Pair” is in sale since Friday, August 16, 2019. This item is in the category “Consumer Electronics\Vintage Electronics\Vintage Audio & Video\Vintage Speakers”. The seller is “jones_road” and is located in Breaux Bridge, Louisiana. This item can be shipped to United States.

These are in excellent condition! They have been meticulously restored by a professional tech. Old caps have been replaced with new audiophile grade caps, and x-covers tuned to bring out the original (if not better) sonic qualities. I can send a pic of the old caps that were removed if you want. The typically noisy pots have been cleaned, and woofer surrounds replaced professionally. Cosmetically, they are in excellent shape. If it wasn’t for a very small nick on one the edges (pic to be uploaded later), i would’ve rated the finish as excellent to near mint. The grill cloths and badges are all original and in very good condition too. The item “Acoustic Research AR3a Speakers professionally restored” is in sale since Sunday, April 23, 2017.
