I've got 2 - 12" Sony Xplod subwoofers that kick out 1200W peak and 350W RMS. They're in brand new condition with slight dust between the rubber seal and the outside mounting ring because I left them sitting in my closet for a while. I cleaned them up and hooked 'em up to my buddy's amp and they are still working great.
$120 shipped.

In the last picture you can see the small amount of dust I couldn't get out from inbetween the rubber and the mount ring.
