Short answer: the REL Acoustics T/7x, if you are buying new. The MartinLogan Dynamo 1100X ranks higher than it (#37 vs #144 of 212 subwoofers, 3.9/5 vs 3.6/5) but is discontinued, so only consider it used; the REL Acoustics T/7x is still sold new at $1,199.
What the REL Acoustics T/7x does well: A compact 8 inch REL subwoofer with a passive radiator and speaker level plus LFE inputs for music and movies at once. The catch: No independent measurements yet, so its output can’t be compared with ranked subwoofers.
The case for the MartinLogan Dynamo 1100X: A compact sealed 12 inch subwoofer with punchy deep bass and built in room correction, now discontinued. Watch for: Output falls to 90.6dB at 15Hz and 95.9dB at 20Hz, which is limited for infrasonic effects in a large room.
Buy the REL Acoustics T/7x if you want one new; the MartinLogan Dynamo 1100X is discontinued, so only look for it used.
Worth knowing: the REL Acoustics T/7x has not been measured yet. Its rating is estimated from related models, with a likely range of 3.4 to 3.8, so treat this verdict as provisional.
