Acoustic Research AR-93 (1980–1982)
Floor-standing 3-way acoustic suspension loudspeaker with dual side-firing 8-inch woofers, introduced as part of AR’s High Tech series.
Overview
The Acoustic Research AR-93 is a floor-standing loudspeaker produced from 1980 to 1982, introduced in late 1979 as part of AR’s "High Tech" series, emphasizing performance over cosmetic embellishment. It shares the same acoustic suspension design concept as the flagship AR-9 and AR-90, using dual side-facing 8-inch woofers, earning its description as the "little brother to the legendary AR-9." The AR-93 belongs to the "Advanced Reference Series" and is classified among Acoustic Research’s "Classic Models Reference." It features a forward-facing 8-inch cone midrange in a separate sealed compartment and a one-inch dome tweeter, with a complex crossover network.

Design
The AR-93 uses an acoustic suspension (sealed box) enclosure with a dual-chamber design, isolating the midrange driver in its own sealed compartment. It features a complex crossover and a wrap-around sock-style grille with top caps. The tweeter is noted as a potential weak point, with users reporting significant sound improvement after upgrading to high-quality 3/4” Vifa units. The woofers are prone to foam degradation and may require refoaming, a common and straightforward repair.
Context
The AR-93 was positioned as the "little brother" to the AR-9, while the AR-94 was described as the "lesser brother of the AR-93." The model was part of a performance-focused lineup known as the "High Tech" series, where engineering took precedence over cosmetic features.
Market
A used pair was listed for CAD $350.00 as of July 10, 2016, and another for CAD $280.00 as of April 12, 2009. Common issues include dried ferrofluid in the tweeters and foam rot in the woofers, both repairable. Some units have had their binding posts upgraded, and the fabric grilles may require repair. One listing noted the speakers were re-foamed ten years prior and saw little use since, with no signs of cracking.
