Short answer: the Dayton Audio MKSX4. It ranks #19 of 73 subwoofers by sound quality, rated 3.6/5, at $144.98; the Monoprice Premium Select 8in 200-Watt ranks #46, rated 3.2/5, and costs $224.99, so there is little reason to consider the other one.
The case for the Monoprice Premium Select 8in 200-Watt: A low cost ported 8 inch subwoofer with a 200 watt amp, an easy entry point for a first subwoofer. Watch for: Very compact 18.5 lbs (8.4 kg) size, limited 106.4 dB output, ported room interaction, and entry-level build.
The Dayton Audio MKSX4 is the better-sounding option. A very low profile subwoofer with four 4 inch drivers that slides under a couch or bed, with good output for the money. 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 is rated higher for sound quality than the Monoprice Premium Select 8in 200-Watt and costs less, which makes it the one to get unless you need something the other one does better.
