Short answer: the Definitive Technology Descend DN15, if you are buying new. The HSU Research VTF-3 MK3 measures as well as it (#97 vs #99 of 110 subwoofers, 3.7/5 vs 3.7/5) but is discontinued, so only consider it used; the Definitive Technology Descend DN15 is still sold new at $1,999.
The case for the HSU Research VTF-3 MK3: Independent CEA-2010 testing records 104.3 dB at 20 Hz and 113.5 dB through 40-80 Hz. 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.
Why pick the Definitive Technology Descend DN15: Independent CEA-2010 testing records 103.9 dB at 20 Hz and 112.9 dB through 40-80 Hz. Watch for: Output tops out lower than other large subwoofers in this price range, and there’s no XLR input.
Buy the Definitive Technology Descend DN15 if you want one new; the HSU Research VTF-3 MK3 is discontinued, so only look for it used.

HSU Research VTF-3 MK3: $1499 Discontinued eBay
Newer model: the HSU Research VTF-3 MK5 HP, rated 4.2/5.
Pros: Independent CEA-2010 testing records 104.3 dB at 20 Hz and 113.5 dB through 40-80 Hz. The ported, rear enclosure with 12” (305mm) driver delivers substantial upper-bass output for movie effects and music.
Cons: 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. The 546.1H x 431.8W x 635.0D mm cabinet and 40.8 kg mass still require deliberate placement and calibration. Discontinued.
