I had one of those before a power surge took it out. Awesome subwoofer for it's size, It dug pretty deep, easily mid 20s and had great slam. We got the AS-P4000 as a replacement and it's not nearly as good. Plays decently deep and is loud but it's really boomy. The volume knob is messed up as well, move it a millimeter and it starts bottoming out.
