The Aerial Model SW12 is a very powerful yet relatively compact and musical subwoofer for use in the best music and home theater systems. It provides solid, quick, accurate bass flat to below 20 Hz. The woofer is a new 12.5" unit weighing 30 lbs. A huge magnet, 3" coil, and dual suspension move its strong aluminum cone linearly almost 2". Bass damping is electrically adjustable. A high quality, high-current 400 watt amplifier and a full-featured 2-channel crossover are provided. To reduce standing wave problems and provide custom response tailoring, a parametric equalizer is included. The heavy cabinet is extensively braced and has a 2" thick front. The IR remote control is machined from solid aluminum.
