Short answer: the Monoprice SW-15. It ranks #13 of 145 subwoofers by sound quality at $374.99; the BIC America PL-300 ranks #63 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 BIC America PL-300 offers: 12-inch triple-ported variable tuning with 350W RMS offers unusually low 20Hz extension under $500. Three-port design delivers more output than single-port competitors. Beefy amp ensures distortion-free sound. Watch for: No detailed measurement caveats are currently recorded.
