Short answer: the Onkyo SKW-204. It ranks #3 of 48 subwoofers by sound quality, rated 3.8/5, at $299. The Polk Audio PSW10 ranks #17, rated 3.4/5, at $249, $50 cheaper, not enough of a saving to outweigh the sound-quality gap.

The case for the Polk Audio PSW10: 10-inch Dynamic Balance polymer composite driver with 100W Peak Class D amp. Set against that: Budget-tier construction, ported room dependency, lower 110.3 dB output, and $250 entry-level positioning.
One note: the Onkyo SKW-204 is discontinued, but it still ranks #3 of 48 subwoofers by sound quality, ahead of most of what is still sold new, so it is worth considering used.
Buy the Onkyo SKW-204. It is rated higher for sound quality, and saving $50 with the Polk Audio PSW10 does not make up for the sound-quality gap.

The Two Speakers In Full
Onkyo SKW-204: $299 Discontinued eBay
Pros: Independent CEA-2010 testing records 77.3 dB at 20 Hz and 115.9 dB through 40-80 Hz. The ported, front enclosure with 10” (254mm) 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 472.9H x 274.6W x 428.5D mm cabinet and 11.8 kg mass still require deliberate placement and calibration. Discontinued.

Polk Power Port channels airflow cleanly for tighter bass without port noise. Best for average/small rooms and apartments.
