Acoustic Research was a Cambridge, Massachusetts-based company that manufactured high-end audio equipment. The brand is now owned by VOXX. Acoustic Research was well known for the AR-3 series of speaker systems, which used the 12-inch (305 mm) acoustic suspension woofer of the AR-1 with newly designed dome mid-range speaker and high-frequency drivers, which were the first of their kind. AR's line of acoustic suspension speakers was extraordinary for its time, as they were the first loudspeakers with flat response, extended bass, wide dispersion, small size, and reasonable cost.
