The product of a joint effort between Onkyo and an unnamed but (said to be) renouned guitar maker, the Onkyo A-OMF combines a 10cm deiameter woofer and ring-drive tweeter in a cabinet just over 10" high and weighing about 7 lbs. The cabinet's side panels, not much thicker than the shell of a guitar, were vibrating quite lustily during the demo. But a knuckle rap test suggested that they are also well damped. Leo Kottke fans rejoice.
