These vintage Acoustic Research AR-3 speakers are a rare find for any audiophile. The speakers were made in the United States and are of the unit type. The brand Acoustic Research is known for their high-quality audio equipment, and these speakers are no exception. They are perfect for vintage audio and video enthusiasts and collectors. Don’t miss out on the opportunity to add these rare AR-3 speakers to your collection. These AR3 speakers were found in my local savers store, consecutive numbers 39208 and 39209, I didn’t hesitate on getting them cause the price was right lol, took them home and sadly they didn’t worked as I spected and because the price was right i decided to give it a full restoration. Started by pulling the grills off, it was a nightmare, I started with the woofers, they were removed and they were fully redone using the original original cones and foams then I removed the mids and highs and sent them to be done by the master Roy Champagne in New York, cabinets were touched a bit as well, pots were totally apart and cleaned, crossover fully redone and finally a new made frames with new KLH fabric speakers I had laying around. The results are amazing!!!! They’re ready for some more decades of fine music. After 6 months of listening I think i’m ready to let them go, they deserve a home where they can sing every day.. DECLARE AS A GIFT OR.

The Acoustic Research AR90 is one of the most celebrated floorstanding speakers ever produced. Designed in the late 1970s under Teledyne’s stewardship of the AR brand, the AR90 was AR’s flagship 4-way loudspeaker system and represented the pinnacle of their acoustic suspension engineering. Featuring a 12″ woofer, a 6″ lower midrange, a 2″ upper midrange dome, and a 3/4″ tweeter, the AR90 delivers a remarkably coherent and musical soundstage that few vintage speakers can match. Its wide frequency response, tight bass reproduction, and smooth highs made it a reference-class speaker in its day and it remains highly sought after by audiophiles who know what they’re listening to. These are working, fully functional AR90s that have been actively enjoyed in a real hi-fi system. I’ve been running them with a NAD preamp/amp stack and they sound absolutely phenomenal: detailed mids, tight and extended bass, and smooth highs with zero distortion or rattling. That said, I want to be fully transparent. The foam surrounds on the woofers have some tears and small holes. This is extremely common on AR90s of this era as the original foam degrades over time. Despite the surround condition, both woofers are functioning and the bass response remains strong. Cabinets show age-appropriate cosmetic wear consistent with vintage speakers from this era. All drivers produce sound, tweeters and midranges are in great shape. What You’re Getting. This is a rare opportunity to own a pair of genuine AR90s, a speaker that competes with and often beats modern speakers costing several times more. Whether you want to recap the crossovers and reseal the surrounds for a full restoration or just plug them in and enjoy the music, these deliver.
