Short answer: the Monoprice Monolith M-10 V2, if you are buying new. The JBL HDI-1200P ranks higher than it (#32 vs #161 of 212 subwoofers, 3.9/5 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.
Why pick the Monoprice Monolith M-10 V2: A THX certified 10 inch ported subwoofer with a heavy cabinet, balanced inputs and two EQ modes. Watch for: The output figures come from the manufacturer rather than an independent lab.
The JBL HDI-1200P is the better-sounding option. A compact 12 inch subwoofer with a powerful amp, low distortion and adjustable crossover and phase for easy blending, now discontinued. Watch for: Output drops quickly below the port tuning, to 93.2dB at 25Hz against 109.5dB at 31.5Hz, so the deepest effects are limited.
Buy the Monoprice Monolith M-10 V2 new; the JBL HDI-1200P is no longer sold new, so it only makes sense as a used find.
