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 #37 (rated 3.9/5) for the MartinLogan Dynamo 1100X.
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. The catch: Output falls to 86.2dB at 15Hz, so the very lowest effects are weaker than the strong midbass numbers suggest.
The case for the MartinLogan Dynamo 1100X: A compact sealed 12 inch subwoofer with punchy deep bass and built in room correction, now discontinued. The catch: Output falls to 90.6dB at 15Hz and 95.9dB at 20Hz, which is limited for infrasonic effects in a large room.
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.
