Sony - SA-WM500 Speaker

Sony SA WM500

The Sony SA-WM500 is a powerful active subwoofer known for its deep bass performance, ideal for both cinema and music. It is a long-throw model, meaning the woofer can travel a large excursion to move substantial amounts of air. Thanks to the sturdy enclosure and the hefty 12 inch woofer, this is one of the larger consumer subwoofers Sony has released, perfect for making those really deep vibrations in films tangible.

Frequency Response: 20 Hz / 200 Hz
Crossover Frequency: 50 Hz / 200 Hz (continuously variable)
Phase Control: 0° or 180° (switchable)
Inputs: Line Level (RCA), Level (binding posts)

The subwoofer works perfectly.
