Short answer: the Arendal 1723 Subwoofer 2S, if you are buying new. The HSU Research VTF-15H MK2 ranks higher than it (#57 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. The HSU Research VTF-15H MK2’s replacement, the HSU Research VTF-TN1, is rated 3.9/5 at $1,249.
The case for the HSU Research VTF-15H MK2: A 15 inch ported subwoofer from a long running series, with strong output for movies at a reasonable price. Watch for: Ported enclosure prone to room modes at certain frequencies, mid-large 110.2 lbs (50 kg) size, and $1499 price point.
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 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 Arendal 1723 Subwoofer 2S if you want one new; the HSU Research VTF-15H MK2 is discontinued, so only look for it used.
