Sony SA-WMP40 120 watt subwoofer 

What did you pay for it?

@@DNDCarandHomeTheateraudioI paid $50, had been sitting in storage for near on 10 years according to the elderly man I bought it off

@akaZyloh It's an amazing sub at that price point. That being said you could for $600.00 have something like this with 1200 watts of power. Or $500 have the 10" version. Sample video. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DOM98XvXcGQ.htmlfeature=shared I build these on a regular basis and can even do one for as little as $300.00
