Short answer: the Onkyo SKW-204 on measured sound quality, the Monoprice Premium Select 8in 200-Watt on price. The Onkyo SKW-204 ranks #3 of 48 subwoofers at $299. The Monoprice Premium Select 8in 200-Watt ranks #33 at $224.99, $74.01 cheaper.

What the Monoprice Premium Select 8in 200-Watt offers: 8-inch ported driver still manages 106.4dB CEA-2010-A average at the lowest price of any subwoofer tested in this weight class. An easy entry point for a first subwoofer. Watch for: Very compact 8.4 kg size, limited 106.4 dB output, ported room interaction, and entry-level build.
What the Onkyo SKW-204 offers: Independent CEA-2010 testing records 77.3 dB at 20 Hz and 115.9 dB through 40-80 Hz. The ported, front enclosure with 10” (254mm) driver delivers substantial upper-bass output for movie effects and music. Watch for: 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. The 472.9H x 274.6W x 428.5D mm cabinet and 11.8 kg mass still require deliberate placement and calibration.
Buy the Monoprice Premium Select 8in 200-Watt when the price outweighs sound quality for you, and the Onkyo SKW-204 when sound quality outweighs the price instead.
