Acoustic Research AR91 Speakers Very Clean One Owner Manual Sound Fantastic

One owner pair of Acoustic Research AR91 speakers. The speakers are all original. The woofers were professionally re-foamed about 8-10 years ago. They sound great and everything works as it should. The cabinets are in better than excellent condition. Just a few hairlines in the veneer on the tops and some minor wear on the painted edges of the lower front and back panels. The grills are perfect. No holes and no snags. Original owners manual included.

2 Acoustic Research #200003 Woofers Speakers Re-foamed AR91 9 11 3A

Offered here is a working pair of Acoustic Research model #200003 woofers in good used condition. When removed from their enclosures, one of them still had the #200003 part number sticker on the frame, but it lost. They have had new foam surrounds installed and have been tested for sound. They measure 12″ across the widest part of the front of the frame (11-1/2″ bolt pattern). When re-foaming was done, the original 2 dust caps were removed & the voice coils shimmed and centered. They were replaced with 4.5 dust caps… Same speaker, bigger dust caps. They both ohm out at 2.5 ohms DCR. Typical and normal DCR measurements for vintage speakers designed to operate at 4 ohms impedance. These were harvested from a pair of AR91 enclosures, but this model was also used in many other AR enclosures. PLEASE do your research to insure proper fit in your enclosure! Cosmetic condition is used. They show minor wear from use and age and do not look new. Please be sure to view all of the pictures. I take care of the service & maintenance routines and cleaning so you don’t have to do it or pay to have it done. I provide clear, quality pictures of the item and strive to accurately represent every item I sell. Additional pictures may available upon request. I will do my best to answer as promptly as I can.
