Short answer: the Dayton Audio CS1200. It ranks #8 of 145 subwoofers by sound quality at $239.98; the Monoprice SW-15 ranks #13 and costs $374.99, so there is not much of a tradeoff to weigh.
What the Monoprice SW-15 offers: 15-inch ported with 600W RMS (800W peak) delivers Large-room Bassaholic rating. Unrivaled mid-bass punch for $375. Strong output with clean control. Dual speaker-level inputs and 40-150Hz crossover for flexible hookup. Watch for: Budget-tier design, ported room gain dependency, 30 kg mid-size, and limited dynamic headroom.
What the Dayton Audio CS1200 offers: Independent CEA-2010 testing records 94.6 dB at 20 Hz and 119.0 dB through 40-80 Hz. The ported enclosure with a 12” driver has real headroom for a mid-size room. Watch for: The 457.2H x 393.7W x 415.8D mm cabinet and 17.6 kg mass still need deliberate placement and calibration.
Buy the Dayton Audio CS1200. It ranks higher for sound quality than the Monoprice SW-15 and costs less, so there is no real case for the other one.
