Here's a picture...
Better than my 15" $500 Velodyne, but won't compare to a $500 cylinder SV Subwoofer. For a 12", it's tight, not boomy. Very very powerful 350 watt amp, probably too much for the woofer, but the woofer has a 70oz magnet. Cadence makes top of the line car audio equipment - thus the only reason I trusted them to buy a home sub. I wasn't disappointed. It fills my 18' x 32' room nicely.
