Short answer: the Klipsch SPL-120, if you are buying new. The MartinLogan Dynamo 1600X ranks higher than it (#3 vs #19 of 212 subwoofers, 4.2/5 vs 4.1/5) but is discontinued, so only consider it used; the Klipsch SPL-120 is still sold new at $429.99.
The case for the MartinLogan Dynamo 1600X: A sealed 15 inch subwoofer with forceful, tight bass, front or down firing setup, and app based room correction, now discontinued. Watch for: Output falls to 86.2dB at 15Hz, so the very lowest effects are weaker than the strong midbass numbers suggest.
Why pick the Klipsch SPL-120: An affordable 12 inch ported subwoofer with room filling, clean bass and optional wireless connection. The catch: Port chuffing is the known flaw: testers could not run it past about 60 to 70% volume before the noise became bothersome, a problem Klipsch fixed in the newer Klipsch RP-1200SW.
Buy the Klipsch SPL-120 if you want one new; the MartinLogan Dynamo 1600X is discontinued, so only look for it used.
