Monitor Audio RSW12 Compact 12" Powered Subwoofer

The Monitor Audio RSW-12 is a compact, high-performance powered subwoofer featuring a 500-watt Class-D amplifier and a 12" front-firing C-CAM driver in a sealed cabinet. Designed for both music and home cinema, it offers 40-120 Hz variable crossover, 0/180-degree phase control, and three EQ settings (Music/Movie/Impact), delivering deep, tight bass in a compact form. It is housed in an attractive Rosewood cabinet, so unlike most subs--which kind of beg to be hidden--this one is pretty enough to display.

This sub is in Very Good condition, with just a few nicks here and there (see pix) but it functions well, pumping out taut, crisp bass.
