Short answer: the Polk Audio PSW108, if you are buying new. The Polk Audio PSW10 measures as well as it (#23 vs #30 of 73 subwoofers, 3.4/5 vs 3.4/5) but is discontinued, so only consider it used; the Polk Audio PSW108 is still sold new at $179.
Why pick the Polk Audio PSW108: A very affordable ported 10 inch subwoofer with line and speaker-level inputs, easy to add to an older receiver or small room. Watch for: The 50W internal amplifier is modest by modern subwoofer standards and will compress or produce audible port turbulence when pushed hard on heavy movie low-frequency effects.
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. Watch for: Budget-tier construction, ported room dependency, lower 110.3 dB output, and $249 entry-level positioning.
Buy the Polk Audio PSW108, since the Polk Audio PSW10 is discontinued and only worth hunting down used.
