HSU Research VTF-3 MK3: $1499 Discontinued eBay

HSU Research VTF-3 MK3 ranking card

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.
