Short answer: the BIC America PL-300. It ranks #89 of 212 subwoofers by sound quality (rated 3.7/5) at $449 and is still sold new; the Monitor Audio RXW12 ranks #135 (rated 3.6/5) and is discontinued, so it is only an option used.
What the BIC America PL-300 does well: An affordable ported 12 inch subwoofer with three ports, adjustable tuning and a strong amplifier. The catch: At 48.1 lbs (21.8 kg) and 457 x 387 x 476mm it is a large, heavy cabinet that needs floor space.
The case for the Monitor Audio RXW12: A sealed 12 inch subwoofer with a strong amplifier for small to medium rooms, now discontinued. The tradeoff: Output drops to 97.9dB at 31.5Hz and 88.9dB at 20Hz, so deep bass is limited.
Buy the BIC America PL-300. It is rated higher for sound quality, and the Monitor Audio RXW12 is discontinued, so it is only available used.
