For sale is a pair of classic Acoustic Research AR-2ax loudspeakers, one of the most respected and historically important acoustic suspension speakers of the late 1960s and early 1970s. Both speakers have been tested and are producing sound from all drivers. These are original vintage speakers and remain excellent candidates for restoration while still retaining their classic AR character. The AR-2ax is widely regarded as one of the landmark loudspeaker designs from Acoustic Research and helped establish the East Coast sound that became famous for its smooth tonal balance, natural vocals, and accurate acoustic presentation. These speakers are known for. Outstanding performance with jazz, vocals, classical, and acoustic music. Historical significance among vintage hi-fi enthusiasts. Many listeners consider the AR-2ax one of the best values in vintage American loudspeakers and a worthy restoration project. Both speakers have been tested and are producing sound. One grille was carefully removed to inspect the drivers and internal condition. The other speaker retains its original intact grille. Both speakers produce sound and are listenable in their current condition. However, as with most original AR speakers of this age, they would benefit significantly from restoration. To restore these speakers closer to their original performance, the following is recommended. Replacement of original crossover capacitors. Cleaning or replacement of the level control potentiometers. Inspection and resealing of the acoustic suspension cabinets if necessary. The potentiometers are a well-known maintenance item on vintage AR speakers and often cause reduced output from the midrange and tweeter circuits. A proper restoration can dramatically improve clarity, high-frequency output, balance, and overall performance. Model: Acoustic Research AR-2ax. Type: 3-Way Acoustic Suspension Speaker. Nominal Impedance: 8 Ohms. Woofer: 10-inch Acoustic Suspension. Frequency Response: Approximately 42Hz – 20kHz. Recommended Amplifier Power: 20-100 Watts. Dimensions and Weight (Approximate). Depth: 11.5 inches. Weight: Approximately 38 lbs each. Please review all photographs carefully as they are part of the description. The cabinets remain attractive overall and retain their original walnut veneer finish. Visible cosmetic wear includes. Minor scratches and finish wear. Edge wear and small veneer imperfections. Light corner wear and small chips. Age-related discoloration and wear consistent with normal use. The original grille cloths remain present and display well overall. These are vintage speakers and should not be expected to be cosmetically perfect. Vintage electronics and loudspeakers may require future maintenance or restoration. This is an excellent opportunity to acquire a genuine pair of AR-2ax speakers that are complete, functional, and ready for restoration. Properly restored AR-2ax speakers remain among the most respected vintage loudspeakers ever produced and continue to have a strong following among audiophiles and collectors.

Hello & welcome to the opportunity to own a pair of original AR-LST speakers (or all 4). Yes I have 2 pair available. LISTING IS FOR ONE PAIR AS SEEN IN PICS, FULLY FUNCTIONING, ORIGINAL, AND READY TO PLUG N PLAY! ONE OWNER since new. At the ripe age of 7 this became my first stereo & began my addiction to quality sound. Always respectfully used, only by my father and myself, never abused! The system was used for about 9 years and then sat quietly in a living room until 1997 when I had a listening space that could do the speakers justice. Around 2010 I had the crossover capacitors upgraded and new foam surrounds placed on the large bass drivers, after testing the speakers sat mostly unused. As you may guess from my photo I have too many large sets of speakers, can’t enjoy them all, these must go to a new home. The oiled walnut cabinets are in the best shape on the pair I show in pics, set #2 have a bit more cabinet wear (UV mostly) and can be nicely refinished if one is careful with the veneer. At the time these speakers, driven by Crown with vinyl as the source, were the most incredible thing I had heard, and remained this way until I spent a fortune and moved up the audiophile ladder (or down the rabbit hole) whichever the reader prefers. This is from AR’s literature, lots of info online for those who wish to read though I recommend hearing over reading! The AR Laboratory Standard Transducer is designed for those laboratory and commercial applications that require conveniently repeatable, accurately known spectral energy profiles, including one flat profile extending from 30Hz to 20 kHz. The AR LST uses a 12 inch acoustic suspension woofer, four 1 1/2 inch mid range hemispherical radiators and four 3/4 inch hemispherical tweeters. The individual speakers are identical with those of the AR-3A system. Crossover frequencies are 575 and 5000Hz. 1 pair of AR-LST speakers & many many years of beautiful sound whether low or high volume.
