Short answer: the Monoprice SW-10. It ranks #111 of 212 subwoofers by sound quality, rated 3.7/5, at $199.99. The Monoprice 12in 150-Watt Powered ranks #126, rated 3.6/5, at $186.25, $13.74 cheaper, a saving that is not big enough to make up the sound-quality gap.
The case for the Monoprice SW-10: The 10” model of Monoprice’s SW series, whose measured Monoprice SW-12 reached 121.2dB in the 40 to 80Hz CEA-2010 bands. The catch: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Monoprice SW-12 and Monoprice SW-15.
Why pick the Monoprice 12in 150-Watt Powered: 12-inch ported with 150W RMS delivers extraordinary output for the price.
Buy the Monoprice SW-10. It is rated higher for sound quality, and saving $13.74 with the Monoprice 12in 150-Watt Powered does not make up for the sound-quality gap.
Worth knowing: the Monoprice SW-10 has not been measured yet. Its rating is estimated from related models, with a likely range of 3.3 to 4.0, so treat this verdict as provisional.

Monoprice SW-10: $199.99 Estimated Amazon eBay
Same family: the Monoprice SW-12 (larger subwoofer, ranked higher, rated 4.2/5) and the Monoprice SW-15 (larger subwoofer, ranked higher, rated 4.1/5).
Pros: The 10” model of Monoprice’s SW series, whose measured Monoprice SW-12 reached 121.2dB in the 40 to 80Hz CEA-2010 bands. It has a 150W RMS (300W peak) amplifier, a down-firing port, variable phase and a variable low pass filter.
Cons: No independent measurements yet, so its output can’t be compared directly with ranked subwoofers; the rating is estimated from the measured Monoprice SW-12 and Monoprice SW-15. Monoprice rates it only to 40Hz, so it gives up the deep extension of the larger models, and the cabinet is a large 50cm cube for a 10” sub.
