Short answer: both are discontinued, so this only matters if you are buying used. Used, the Polk Audio PSW10 is the better pick: it ranks #23 of 73 subwoofers by sound quality (rated 3.4/5), against #35 (rated 3.3/5) for the Klipsch HD Theater 600. If you want one new, the Edifier T5s ranks #2 at $169.99.
What the Polk Audio PSW10 does well: A discontinued affordable 10 inch ported subwoofer, easy to set up and a popular bass add for apartments and small rooms. The catch: Budget-tier construction, ported room dependency, lower 110.3 dB output, and $249 entry-level positioning.
Why pick the Klipsch HD Theater 600: A discontinued compact ported 8 inch subwoofer that adds midbass support to a small home theater system. The tradeoff: Without a published 20 Hz result, deep-bass capability is less certain than the midbass figure.
Buy the Polk Audio PSW10 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.
