Short answer: the Klipsch HD Theater 600. Both are rated 3.3/5 for sound quality (#25 and #27 of 48 subwoofers), and the Klipsch HD Theater 600 costs $399 against $699 for the Monitor Audio BRW10, with sound quality a draw, the lower price decides it.

The case for the Klipsch HD Theater 600: Independent CEA-2010 testing records 108.2 dB (avg of 3/4 bands) through 40-80 Hz. The catch: Without a published 20 Hz result, deep-bass capability is less certain than the midbass figure.
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 catch: 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 Klipsch HD Theater 600 is discontinued and no longer widely available new.
Buy the Klipsch HD Theater 600. Both are rated the same for sound quality, and it costs $300 less than the Monitor Audio BRW10.

Klipsch HD Theater 600: $399 Discontinued eBay
Pros: Independent CEA-2010 testing records 108.2 dB (avg of 3/4 bands) through 40-80 Hz. The ported, rear enclosure with 8” (203mm) driver is a compact way to add useful midbass support to a modest system.
Cons: Without a published 20 Hz result, deep-bass capability is less certain than the midbass figure. The 353.1H x 317.5W x 317.5D mm cabinet and 7.7 kg mass still need careful placement and calibration. Discontinued.

Monitor Audio BRW10: $699 Discontinued eBay
Pros: Independent CEA-2010 testing records 70.1 dB at 20 Hz and 107.0 dB through 40-80 Hz. The ported, rear 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 320.5H x 320.5W x 339.6D mm cabinet and 12.5 kg mass still require deliberate placement and calibration. Discontinued.
