Short answer: the SVS SB-1000 PRO. It ranks #4 of 73 subwoofers by sound quality (rated 3.7/5) at $599 and is still sold new; the MartinLogan Dynamo 700w ranks #25 (rated 3.4/5) and is discontinued, so it is only an option used.
The SVS SB-1000 PRO is the better-sounding option. A compact sealed subwoofer with tight bass and huge output for its weight, best for music and small rooms. The tradeoff: As a sealed box it gives up output in the deepest octave: 91dB at 20Hz and 97.7dB at 25Hz, where a ported subwoofer like the RSL (Rogersound Labs) Speedwoofer 10S MKII reaches 100dB and 105dB.
Why pick the MartinLogan Dynamo 700w: A discontinued compact sealed 10 inch subwoofer that adds upper bass weight to movies and music. Watch for: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority.
Buy the SVS SB-1000 PRO. It is rated higher for sound quality, and the MartinLogan Dynamo 700w is discontinued, so it is only available used.
