Short answer: the SVS SB-1000 PRO. It ranks #4 of 48 subwoofers by sound quality, rated 3.7/5, at $599. The Klipsch Flexus Sub 100 ranks #16, rated 3.4/5, at $349.99, $249.01 cheaper, which does not close the gap in sound quality.
What the SVS SB-1000 PRO does well: 12-inch sealed driver delivers 113.9dB CEA-2010-A average, the highest output of any subwoofer in the under-30lb weight class. Watch for: 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 Speedwoofer 10S MKII reaches 100dB and 105dB.
Why pick the Klipsch Flexus Sub 100: Independent CEA-2010 testing records 90.2 dB at 20 Hz and 109.1 dB (avg of 3/4 bands) through 40-80 Hz. Watch for: Only works with Klipsch Flexus soundbars, not as a standalone LFE sub.
Buy the SVS SB-1000 PRO. It is rated higher for sound quality, and the $249.01 you would save on the Klipsch Flexus Sub 100 does not close the gap.

SVS SB-1000 PRO: $599.00 Amazon eBay
Older models: the SVS SB-1000 (rated 3.9/5) and the SVS SB12-NSD (rated 3.4/5).
Pros: 12-inch sealed driver delivers 113.9dB CEA-2010-A average, the highest output of any subwoofer in the under-30lb weight class. Sealed enclosure keeps bass tight and controlled for its compact footprint.
Cons: 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 Speedwoofer 10S MKII reaches 100dB and 105dB. Its strength is the 50 to 80Hz range, so it suits music and smaller rooms better than movie effects that dig below 30Hz.

Klipsch Flexus Sub 100: $349.99 Amazon eBay
Pros: Independent CEA-2010 testing records 90.2 dB at 20 Hz and 109.1 dB (avg of 3/4 bands) through 40-80 Hz. The sealed enclosure with a 10” driver suits a small room.
Cons: Only works with Klipsch Flexus soundbars, not as a standalone LFE sub. The 339.9H x 335.0W x 349.2D mm cabinet and 9.4 kg mass still need deliberate placement.
