Short answer: the BIC America PL-300, if you are buying new. The MartinLogan Dynamo 1600X ranks higher than it (#3 vs #89 of 212 subwoofers, 4.2/5 vs 3.7/5) but is discontinued, so only consider it used; the BIC America PL-300 is still sold new at $449.
The MartinLogan Dynamo 1600X is the better-sounding pick. A sealed 15 inch subwoofer with forceful, tight bass, front or down firing setup, and app based room correction, now discontinued. The catch: Output falls to 86.2dB at 15Hz, so the very lowest effects are weaker than the strong midbass numbers suggest.
What the BIC America PL-300 does well: An affordable ported 12 inch subwoofer with three ports, adjustable tuning and a strong amplifier. The tradeoff: At 48.1 lbs (21.8 kg) and 457 x 387 x 476mm it is a large, heavy cabinet that needs floor space.
Buy the BIC America PL-300 if you want one new; the MartinLogan Dynamo 1600X is discontinued, so only look for it used.
