Short answer: the SVS SB-1000 PRO. It ranks #4 of 73 subwoofers by sound quality, rated 3.7/5, at $599. The Klipsch Flexus Sub 100 ranks #22, rated 3.4/5, at $349, $250 cheaper, which does not close the gap in sound quality.
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. 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 (Rogersound Labs) Speedwoofer 10S MKII reaches 100dB and 105dB.
Why pick the Klipsch Flexus Sub 100: A compact sealed 10 inch subwoofer made to add bass to a Klipsch Flexus soundbar in a small room. 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 $250 you would save on the Klipsch Flexus Sub 100 does not close the gap.
