Short answer: the Rythmik F12, if you are buying new. The Power Sound Audio (PSA) XV15 measures as well as it (#10 vs #21 of 212 subwoofers, 4.1/5 vs 4.1/5) but is discontinued, so only consider it used; the Rythmik F12 is still sold new at $1,439.
What the Rythmik F12 does well: A sealed servo subwoofer with deep, musical bass and excellent build quality, a strong value for music lovers. The catch: The sealed 12-inch driver cannot reproduce the deepest cinema effects, so a pair is advised for theater.
What the Power Sound Audio (PSA) XV15 does well: A down firing 15 inch ported subwoofer with deep, clean, detailed bass that plays loud, now discontinued but worth buying used. The catch: It weighs 75 lbs (34.0 kg) in a 584 x 432 x 559 mm cabinet, so it needs a lot of space.
Buy the Rythmik F12 if you want one new; the Power Sound Audio (PSA) XV15 is discontinued, so only look for it used.
