Short answer: the Klipsch SPL-120. It ranks #19 of 212 subwoofers by sound quality, rated 4.1/5, at $429.99. The Monoprice SSW-10 ranks #98, rated 3.7/5, at $242.99, $187 cheaper, a saving that is not big enough to make up the sound-quality gap.
Why pick the Monoprice SSW-10: A slim subwoofer that fits under furniture, with decent output for its size and a low price. Watch for: Output drops to 85.2dB at 25Hz and 76.8dB at 20Hz, so there is little deep bass.
The Klipsch SPL-120 is the better-sounding pick. An affordable 12 inch ported subwoofer with room filling, clean bass and optional wireless connection. The tradeoff: Port chuffing is the known flaw: testers could not run it past about 60 to 70% volume before the noise became bothersome, a problem Klipsch fixed in the newer Klipsch RP-1200SW.
Buy the Klipsch SPL-120. It is rated higher for sound quality, and the $187 saving on the Monoprice SSW-10 is not enough to make up the difference.
