HSU Research VTF-15H: $1,199 Discontinued eBay
Newer model: the HSU Research VTF-15H MK2, ranked higher, rated 4.2/5.
Pros: Independent CEA-2010 testing records 107.1 dB at 20 Hz and 118.4 dB through 40-80 Hz. The ported, front enclosure with 15” (381mm) driver has the headroom for demanding film bass in a large room.
Cons: The 635.0H x 457.2W x 660.4D mm cabinet and 55.8 kg mass make this a serious placement and moving commitment. Ported output does not solve room modes, so careful placement and calibration remain essential. Discontinued.
