Short answer: both are discontinued, so this only matters if you are buying used. Used, the MartinLogan Dynamo 1600X is the better pick: it ranks #3 of 212 subwoofers by sound quality (rated 4.2/5), against #69 (rated 3.8/5) for the Dayton Audio SUB-1200. If you want one new, the Dayton Audio CS1200 replaces the Dayton Audio SUB-1200 and is rated 4.1/5 at $239.98.
The MartinLogan Dynamo 1600X is the better-sounding choice. 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 Dayton Audio SUB-1200: A very affordable ported 12 inch subwoofer with solid output, an adjustable crossover and speaker level connections, now discontinued. Watch for: Rolls off earlier in the low bass than the Infinity and Jamo 12-inch subs it was measured against, so it lacks their depth.
Buy the MartinLogan Dynamo 1600X only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, buy the Dayton Audio CS1200, which replaces the Dayton Audio SUB-1200.
