Short answer: the Monoprice Premium Select 8in 200-Watt. It ranks #46 of 73 subwoofers by sound quality, rated 3.2/5, at $224.99. The Yamaha NS-SW050 ranks #68, rated 2.7/5, at $219.95, $5.04 cheaper, which does not close the gap in sound quality.
The Monoprice Premium Select 8in 200-Watt is the better-sounding choice. 8-inch ported driver still manages 106.4dB CEA-2010-A average at the lowest price of any subwoofer tested in this weight class. The catch: Very compact 18.5 lbs (8.4 kg) size, limited 106.4 dB output, ported room interaction, and entry-level build.
Why pick the Yamaha NS-SW050: Yamaha’s smallest home subwoofer, with an 8” cone, Advanced YST II servo amplification and a Twisted Flare Port to reduce port noise. The catch: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Yamaha NS-SW100, which reached only 105.0dB in the 40 to 80Hz CEA-2010 bands.
Buy the Monoprice Premium Select 8in 200-Watt. It is rated higher for sound quality, and the $5.04 you would save on the Yamaha NS-SW050 does not close the gap.
About the ratings: the Yamaha NS-SW050’s rating is estimated from measured siblings and predecessors rather than its own measurements, with a likely range of 2.3 to 3.0, so this verdict could change once it is measured.

Yamaha NS-SW050: $219.95 Estimated Amazon eBay
Same family: the Yamaha NS-SW100 (larger subwoofer, ranked higher, rated 3/5).
Pros: Yamaha’s smallest home subwoofer, with an 8” cone, Advanced YST II servo amplification and a Twisted Flare Port to reduce port noise. Rated 28 to 200Hz in a cabinet 29cm wide.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Yamaha NS-SW100, which reached only 105.0dB in the 40 to 80Hz CEA-2010 bands. With an 8” driver and 50W it is suited to small rooms and modest levels.
