Short answer: the Monoprice SW-15. It ranks #14 of 212 subwoofers by sound quality (rated 4.1/5) at $499.99 and is still sold new; the HSU Research MBM-12 ranks #58 (rated 3.8/5) and is discontinued, so it is only an option used.
The case for the Monoprice SW-15: A big 15 inch subwoofer with powerful, punchy bass at a budget price, great for movies in a large room. The tradeoff: Budget-tier design, ported room gain dependency, 66.1 lbs (30 kg) mid-size, and limited dynamic headroom.
The case for the HSU Research MBM-12: A 12 inch mid bass module with switchable sealed or ported tuning, built for fast, punchy upper bass rather than deep rumble. Watch for: It is not a true subwoofer, with output falling to 96.7dB at 31.5Hz and 69.7dB at 20Hz, so it will not deliver deep movie rumble.
Buy the Monoprice SW-15. It is rated higher for sound quality; the HSU Research MBM-12 is no longer sold new.
