Short answer: the Monoprice SW-12 for output and bass impact, the SSW-10 if the slim cabinet matters. The SW-12 is a 12-inch ported sub with 400W RMS (600W peak) that hits hard with clean, tight transient response, though its entry-level build and ported room interaction are caveats. The SSW-10 is an ultra-slim sealed 10-inch just 7” tall with 150W RMS and a 108.2dB average, and it costs $29.26 more.
What the Monoprice SSW-10 gets right: 10-inch ultra-slim sealed (7” height) with 150W RMS, 108.2dB average.
On the Monoprice SW-12 side: 12-inch ported with 400W RMS (600W peak) on a budget at just $230. Hits hard with clean tight transient response. Set against that: Entry-level build quality, ported enclosure room interaction, and lower 112.3 dB output capability.
Buy the Monoprice SW-12. It is rated higher for sound quality than the Monoprice SSW-10 and costs less, so there is no real case for the other one.
