Short answer: the HSU Research VTF-3 MK5 HP. It ranks #59 of 143 subwoofers by sound quality (rated 4.2/5) at $1,049 and is still sold new; the Monoprice Monolith M-210 ranks #116 (rated 3.9/5) and is discontinued, so it is only an option used.
The HSU Research VTF-3 MK5 HP is the better-sounding option. A 15 inch ported subwoofer with excellent output for the money, a strong value pick for movies and music. Watch for: Ported design requires careful room placement, mid-size 86 lbs (39 kg) cabinet, and mid-range output.
What the Monoprice Monolith M-210 does well: A tall dual 10 inch ported subwoofer with strong upper bass for movies and music, now discontinued. The tradeoff: Deep-bass output is more limited than the strong 40-80 Hz result suggests, so it is not the right choice when the lowest movie effects are the priority.
Buy the HSU Research VTF-3 MK5 HP. It is rated higher for sound quality; the Monoprice Monolith M-210 is no longer sold new.
