Short answer: the Velodyne Acoustics SPL-1200 Series II. It ranks #2 of 42 subwoofers at $499; the Paradigm Defiance V12 ranks #76 and costs $513.44, so there is not much of a tradeoff to weigh.
On the Paradigm Defiance V12 side: Fills rooms with tight ample powerful bass while retaining speed/control of sealed design.
The case for the Velodyne Acoustics SPL-1200 Series II: 12-inch sealed driver reaches 111.1dB CEA-2010-A average, second only to the pricier SVS SB-1000 PRO among compact subwoofers. Set against that: Small sealed driver limits extension below 20 Hz and 9.5 kg compact size.
One note: the Velodyne Acoustics SPL-1200 Series II is discontinued, but it still ranks #2 of 42 subwoofers, ahead of most of what is still sold new, so it is worth considering used.
Buy the Paradigm Defiance V12 if the price matters more than the ranking. Buy the Velodyne Acoustics SPL-1200 Series II if the ranking matters more than the price.
