Short answer: the Monoprice SW-15. It ranks #13 of 145 subwoofers by sound quality at $374.99; the Jamo C 912 SUB ranks #131 and costs $599, so there is not much of a tradeoff to weigh.

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 Jamo C 912 SUB offers: 12-inch ported with 200W RMS outputs fairly accurate smooth bass for music and movies. Relaxed energetic low-frequency presentation without listening fatigue. Front-facing port enables flexible placement. Watch for: No detailed measurement caveats are currently recorded.

Buy the Monoprice SW-15. It ranks higher for sound quality than the Jamo C 912 SUB and costs less, which settles it without a real tradeoff to make.
