Short answer: the Monoprice Monolith M-10 V2, if you are buying new. The Power Sound Audio (PSA) XV15 ranks higher than it (#10 vs #161 of 212 subwoofers, 4.1/5 vs 3.4/5) but is discontinued, so only consider it used; the Monoprice Monolith M-10 V2 is still sold new at $728.44.
What the Monoprice Monolith M-10 V2 does well: A THX certified 10 inch ported subwoofer with a heavy cabinet, balanced inputs and two EQ modes. The tradeoff: The output figures come from the manufacturer rather than an independent lab.
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 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 Monoprice Monolith M-10 V2, since the Power Sound Audio (PSA) XV15 is discontinued and only worth hunting down used.
