Short answer: the XTZ Sound 99 W12S, if you are buying new. The MartinLogan Dynamo 1600X ranks higher than it (#3 vs #61 of 212 subwoofers, 4.2/5 vs 3.8/5) but is discontinued, so only consider it used; the XTZ Sound 99 W12S is still sold new at $1,499.
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 tradeoff: Output falls to 86.2dB at 15Hz, so the very lowest effects are weaker than the strong midbass numbers suggest.
What the XTZ Sound 99 W12S does well: A ported 12 inch subwoofer with a strong amplifier, phase control and EQ switches for tuning it to the room. Watch for: Deep output falls off sharply, with 86.5dB at 25Hz and 74.0dB at 20Hz, so it is weak for the lowest movie effects.
Buy the XTZ Sound 99 W12S, since the MartinLogan Dynamo 1600X is discontinued and only worth hunting down used.
