Short answer: both are discontinued, so this only matters if you are buying used. Used, the Onkyo SKW-204 is the better pick: it ranks #3 of 73 subwoofers by sound quality (rated 3.8/5), against #23 (rated 3.4/5) for the Polk Audio PSW10. If you want one new, the Edifier T5s ranks #2 at $199.99.
Buy the Onkyo SKW-204 only if you find one used in good condition; both are discontinued, and it is the better rated of the two. For a new speaker, start with the Edifier T5s instead.
