Short answer: the Monoprice SSW-10, if you are buying new. The Power Sound Audio (PSA) XV15 ranks higher than it (#10 vs #98 of 212 subwoofers, 4.1/5 vs 3.7/5) but is discontinued, so only consider it used; the Monoprice SSW-10 is still sold new at $242.99.
The Power Sound Audio (PSA) XV15 is the better-sounding option. A down firing 15 inch ported subwoofer with deep, clean, detailed bass that plays loud, now discontinued but worth buying used. The tradeoff: It weighs 75 lbs (34.0 kg) in a 584 x 432 x 559 mm cabinet, so it needs a lot of space.
The case for the Monoprice SSW-10: A slim subwoofer that fits under furniture, with decent output for its size and a low price. Watch for: Output drops to 85.2dB at 25Hz and 76.8dB at 20Hz, so there is little deep bass.
Buy the Monoprice SSW-10 new; the Power Sound Audio (PSA) XV15 is no longer sold new, so it only makes sense as a used find.
