Acoustic Research 28B 2-Way Acoustic Suspension Speaker – only one. It was working when taken out of service a long time ago. Obviously the woofer surround is gone. This unit features the tried and true 2-way acoustic suspension design with a USA made 8? Woofer and a 1.25? Dome tweeter crossed over at a relatively high 5,000HZ. This is one of the AR speaker models succeeding the original AR-4 models. Cabinet is in very good condition – nearly defect free – and measure a compact 20x11x7.25, finished with good quality wood grain vinyl. Grille dust cover is included and is in very good condition. Overall condition is very good with near zero cosmetic issues, limited to a few tiny scuffs and edge nicks. The grille is also in very good condition with no snags and only some some light corner wear. Please see all pictures for full condition detail. Country/Region of Manufacture: United States.
