Short answer: the Dayton Audio MKSX4. It ranks #14 of 48 subwoofers by sound quality at $144.98; the Monoprice Premium Select 8in 200-Watt ranks #33 and costs $224.99, so there is little reason to consider the other one.
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 Dayton Audio MKSX4 offers: Four 4-inch drivers in a low-profile (under 8-inch) cabinet deliver 106.2dB CEA-2010-A average, the best output-per-dollar of any passive subwoofer tested. Watch for: Budget-tier output at 112.2 dB, four small 4-inch drivers, ported room dependency, and $145 price point.
Buy the Dayton Audio MKSX4. It ranks higher for sound quality than the Monoprice Premium Select 8in 200-Watt and costs less, so the other one has nothing left to offer.
