Short answer: the MartinLogan Dynamo 700w. It ranks #19 of 48 subwoofers by sound quality, rated 3.4/5, at $999. The Monitor Audio BRW10 ranks #27, rated 3.3/5, at $699, $300 cheaper, a saving that is not big enough to make up the sound-quality gap.

Why pick the MartinLogan Dynamo 700w: Independent CEA-2010 testing records 86.3 dB at 20 Hz and 109.0 dB (avg of 3/4 bands) through 40-80 Hz. The tradeoff: 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.
What the Monitor Audio BRW10 does well: Independent CEA-2010 testing records 70.1 dB at 20 Hz and 107.0 dB through 40-80 Hz. The tradeoff: 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.
One note: the MartinLogan Dynamo 700w is discontinued, but it still ranks #19 of 48 subwoofers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the MartinLogan Dynamo 700w. It is rated higher for sound quality, and the $300 saving on the Monitor Audio BRW10 is not enough to make up the difference.

MartinLogan Dynamo 700w: $999 Discontinued eBay
Pros: Independent CEA-2010 testing records 86.3 dB at 20 Hz and 109.0 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with 10” (254mm) driver delivers substantial upper-bass output for movie effects and music.
Cons: 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. The 318.5H x 296.9W x 318.3D mm cabinet and 12.0 kg mass still require deliberate placement and calibration. Discontinued.
