Short answer: the SVS 3000 Micro on measured sound quality, the Klipsch Flexus Sub 100 on price. The SVS 3000 Micro ranks #6 of 48 subwoofers, rated 3.7/5, at $999. The Klipsch Flexus Sub 100 ranks #16, rated 3.4/5, at $349.99, $649.01 cheaper.
Why pick the SVS 3000 Micro: Independent CEA-2010 testing records 90.6 dB at 20 Hz and 113.5 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.
What the Klipsch Flexus Sub 100 does well: 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 catch: Only works with Klipsch Flexus soundbars, not as a standalone LFE sub.
Buy the SVS 3000 Micro when sound quality outweighs the price for you, and the Klipsch Flexus Sub 100 when the price outweighs sound quality instead.

SVS 3000 Micro: $999.00 Amazon eBay
Pros: Independent CEA-2010 testing records 90.6 dB at 20 Hz and 113.5 dB through 40-80 Hz. The sealed enclosure with 2x 8” (203mm) 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 276.9H x 297.2W x 271.8D mm cabinet and 10.2 kg mass still require deliberate placement and calibration.
