Short answer: the HSU Research VTF-15H MK2. It ranks #50 of 110 subwoofers by sound quality, rated 4.2/5, at $1,499; the Definitive Technology Descend DN15 ranks #99, rated 3.7/5, and costs $1,999, so there is little reason to consider the other one.
The case for the HSU Research VTF-15H MK2: 15-inch ported driver delivers 121.8dB CEA-2010-A average from HSU Research’s long-running VTF series. The tradeoff: Ported enclosure prone to room modes at certain frequencies, mid-large 50 kg size, and $1499 price point.
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. The catch: Output tops out lower than other large subwoofers in this price range, and there’s no XLR input.
