Short answer: the Monoprice SW-15. It ranks #13 of 145 subwoofers by sound quality at $374.99; the Bose Lifestyle Ultra Subwoofer ranks #36 and costs $899, 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 Bose Lifestyle Ultra Subwoofer offers: Independent CEA-2010 testing records 90.6 dB at 20 Hz and 115.4 dB (avg of 3/4 bands) through 40-80 Hz. The ported enclosure with a 12” driver is well suited to a mid-size room. Watch for: The 326.8H x 294.7W x 294.7D mm cabinet and 15.3 kg mass still need deliberate placement and calibration.
Buy the Monoprice SW-15. It ranks higher for sound quality than the Bose Lifestyle Ultra Subwoofer and costs less, so the other one has nothing left to offer.
