Short answer: both are discontinued, so this only matters if you are buying used. Used, the Definitive Technology SuperCube 2000 is the better pick: it ranks #5 of 73 subwoofers by sound quality (rated 3.7/5), against #23 (rated 3.4/5) for the Polk Audio PSW10. 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.
The Definitive Technology SuperCube 2000 is the better-sounding pick. A discontinued very compact subwoofer with a 7.5 inch driver and passive radiator that adds upper bass punch to a small system. The catch: 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.
Buy the Definitive Technology SuperCube 2000 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.
