Short answer: the Monoprice SW-15. It ranks #13 of 145 subwoofers by sound quality at $374.99; the Polk Audio HTS 10 ranks #57 and costs $450, so there is little reason to consider the other one.
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 Polk Audio HTS 10 offers: 10-inch ported with 100W RMS and Polk Power Port maintains relatively clean bass at high volumes. Competent mid-tier option from reliable brand. Good fit for medium rooms without excessive distortion. Watch for: No detailed measurement caveats are currently recorded.
