Short answer: the REL Acoustics HT/1510 Predator II, if you are buying new. The HSU Research VTF-15H MK2 ranks higher than it (#57 vs #98 of 143 subwoofers, 4.2/5 vs 4.1/5) but is discontinued, so only consider it used; the REL Acoustics HT/1510 Predator II is still sold new at $2,199. The HSU Research VTF-15H MK2’s replacement, the HSU Research VTF-TN1, is rated 3.9/5 at $1,249.
Why pick 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.
What the REL Acoustics HT/1510 Predator II does well: A sealed 15 inch home theater subwoofer with strong, punchy upper bass for movie effects and music. 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.
Buy the REL Acoustics HT/1510 Predator II if you want one new; the HSU Research VTF-15H MK2 is discontinued, so only look for it used.
