Short answer: the Klipsch R-121SW, if you are buying new. The Power Sound Audio (PSA) XV15 ranks higher than it (#10 vs #132 of 212 subwoofers, 4.1/5 vs 3.6/5) but is discontinued, so only consider it used; the Klipsch R-121SW is still sold new at $449.99.
The case for the Klipsch R-121SW: A 12 inch front-firing subwoofer with Klipsch’s copper colored woofer, an affordable pick for home theater. The tradeoff: Output drops to 98.4dB at 25Hz and 96.0dB at 20Hz, so the deepest film effects will be weak in a large room.
The Power Sound Audio (PSA) XV15 is the better-sounding pick. A down firing 15 inch ported subwoofer with deep, clean, detailed bass that plays loud, now discontinued but worth buying used. Watch for: 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 Klipsch R-121SW new; the Power Sound Audio (PSA) XV15 is no longer sold new, so it only makes sense as a used find.
