Short answer: the Arendal 1723 Subwoofer 2S, if you are buying new. The Monoprice Monolith M-15 V2 ranks higher than it (#71 vs #82 of 143 subwoofers, 4.2/5 vs 4.1/5) but is discontinued, so only consider it used; the Arendal 1723 Subwoofer 2S is still sold new at $2,500.
Why pick the Arendal 1723 Subwoofer 2S: A sealed subwoofer with two 13.8 inch drivers and strong upper bass punch in a fairly compact cabinet. The catch: 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.
What the Monoprice Monolith M-15 V2 does well: A 15 inch ported subwoofer with strong deep bass and midbass headroom for movies, a good value used. Watch for: Discontinued and no longer sold new.
Buy the Arendal 1723 Subwoofer 2S if you want one new; the Monoprice Monolith M-15 V2 is discontinued, so only look for it used.
