Short answer: the HSU Research VTF-3 MK5 HP. It ranks #52 of 110 subwoofers by sound quality at $1049; the HSU Research VTF-3 MK3 ranks #97 and costs $1499, so there is little reason to consider the other one.
What the HSU Research VTF-3 MK5 HP offers: Ported cabinet delivers 121.4dB CEA-2010-A average, one of the best price-to-output ratios in this weight class. Watch for: Ported design requires careful room placement, mid-size 39 kg cabinet, and mid-range output.
What the HSU Research VTF-3 MK3 offers: 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. Watch for: 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.
Buy the HSU Research VTF-3 MK5 HP. It ranks higher for sound quality than the HSU Research VTF-3 MK3 and costs less, which settles it without a real tradeoff to make.
If sound quality matters at all to you, skip the HSU Research VTF-3 MK3. It ranks near the bottom of the 110 subwoofers, so look higher up the list instead.
