Short answer: the Klipsch Flexus Sub 100. It ranks #16 of 48 subwoofers by sound quality, rated 3.4/5, at $279.99. The Yamaha NS-SW100 ranks #35, rated 3.0/5, at $269.95, $10.04 cheaper, a saving that is not big enough to make up the sound-quality gap.
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. The catch: Only works with Klipsch Flexus soundbars, not as a standalone LFE sub.
The case for the Yamaha NS-SW100: 10-inch ported with 100W RMS.
Buy the Klipsch Flexus Sub 100. It is rated higher for sound quality, and saving $10.04 with the Yamaha NS-SW100 does not make up for the sound-quality gap.

Klipsch Flexus Sub 100: $279.99 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.
