Short answer: the Sony Bravia Theater Sub 7, though neither ranks well in its class. It ranks #63 of 73 subwoofers by sound quality, rated 2.9/5, at $278. The Yamaha NS-SW050 ranks #68, rated 2.7/5, at $219.95, $58.05 cheaper, not enough of a saving to outweigh the sound-quality gap. Both are rated below 3.0/5 among the 73 subwoofers; for better sound, the Edifier T5s ranks #2 at $199.99.
The case for the Sony Bravia Theater Sub 7: A slim wireless subwoofer for Sony’s BRAVIA Theater soundbars, only 134mm deep so it can stand upright or lie flat under a sofa. Watch for: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Sony Bravia Theater Sub 9 (112.8dB in the 40 to 80Hz CEA-2010 bands).
The case for 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 Sony Bravia Theater Sub 7. It is rated higher for sound quality, and saving $58.05 with the Yamaha NS-SW050 does not make up for the sound-quality gap.
About the ratings: neither speaker has been measured yet, so both ratings are estimated from measured siblings and predecessors (likely ranges: Sony Bravia Theater Sub 7 2.5 to 3.2; Yamaha NS-SW050 2.3 to 3.0). Treat this verdict as provisional.

Sony Bravia Theater Sub 7: $278.00 Estimated Amazon eBay
Same family: the Sony Bravia Theater Sub 8 (larger subwoofer, ranked higher, estimated 3.4/5) and the Sony Bravia Theater Sub 9 (larger subwoofer, rated 3.7/5).
Pros: A slim wireless subwoofer for Sony’s BRAVIA Theater soundbars, only 134mm deep so it can stand upright or lie flat under a sofa. It uses a 130mm driver with a 100W S-Master amplifier, and two can be paired.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Sony Bravia Theater Sub 9 (112.8dB in the 40 to 80Hz CEA-2010 bands). A 130mm driver is far smaller than a normal subwoofer’s, so deep bass and output are limited, and it only works with compatible Sony soundbars.
