Very nice Audio Pro B2-50 subwoofer, in walnut, with black grill cloth. Two 6.5" woofers, inputs for high level (anp output) and low level (preamp) outputs. variable input sensitivity (volume) variable (40-200 hz) crossover frequency for both sub and main speakers, auto on. Great reviews on line, Flat to 20 hz,, then steep roll off. Great for use with electrostatics, Quads, Acoustat, high efficiency horns. as it is a very fast, and detailed sub, able to keep up with the fastest main speakers. Internal amp has been gone though in the last year, caps replaced, woofers have rubber surrounds, so it is ready to go! Replaced with an Audio Pro B2-100. Nice condition, looks good, sounds great. This is a truly musical sub.
I would prefer not to ship, but will if desired. Please add $25.00 to cover actual cost of box, and 2 inches of foam packaging.
Includes owners manual, high and low level cables.
Pics to come.
