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 Hsu Research VTF-TN1 ranks #86, rated 3.9/5, at $1,199, $300 cheaper, not enough of a saving to outweigh the sound-quality gap.

Why pick 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 Hsu Research VTF-TN1: Independent CEA-2010 testing (2 ports open) records 107.8 dB at 20 Hz and 117.6 dB through 40-80 Hz. The catch: The tall 29.5” cabinet has an unusual footprint compared to squatter subs in this class.
Buy the HSU Research VTF-15H MK2. It is rated higher for sound quality, and the $300 you would save on the Hsu Research VTF-TN1 does not close the gap.

Hsu Research VTF-TN1: $1,199 eBay
Pros: Independent CEA-2010 testing (2 ports open) records 107.8 dB at 20 Hz and 117.6 dB through 40-80 Hz. Variable tuning via dual 4” down-firing ports lets the 15” driver reach 15Hz in Max Extension mode or 18Hz in Max Output mode. Extremely low distortion until the highest drive levels.
Cons: The tall 29.5” cabinet has an unusual footprint compared to squatter subs in this class.
