Short answer: the Klipsch Flexus Sub 100. It ranks #22 of 73 subwoofers by sound quality, rated 3.4/5, at $349. The Yamaha NS-SW100 ranks #54, rated 3.0/5, at $269.95, $79.05 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Klipsch Flexus Sub 100 is the better-sounding pick. A compact sealed 10 inch subwoofer made to add bass to a Klipsch Flexus soundbar in a small room. The tradeoff: Only works with Klipsch Flexus soundbars, not as a standalone LFE sub.
The case for the Yamaha NS-SW100: An affordable compact ported 10 inch subwoofer with a 100 watt amp and a stylish cabinet. The tradeoff: There is no crossover control and no polarity switch, which makes it harder to blend with main speakers.
Buy the Klipsch Flexus Sub 100. It is rated higher for sound quality, and saving $79.05 with the Yamaha NS-SW100 does not make up for the sound-quality gap.
