Newer model: the HSU Research VTF-3 MK5 HP, rated 4.2/5, released Oct 2014.

Pros: A ported 12 inch subwoofer with big output and deep extension for the money, backed by a long warranty, now discontinued. It measures 105.4dB at 20Hz and 115.3dB average CEA-2010 output from 40 to 80Hz, with a listed response of 18-90Hz. The 350W continuous amplifier (1400W short term) is backed by a 7 year driver and 2 year amplifier warranty.
Cons: At 33.6kg and 546.1H x 431.8W x 635.0D mm it is a large, deep cabinet that needs real floor space. Its output figures come from the manufacturer rather than an independent lab. It is discontinued and replaced by the HSU Research VTF-3 MK5 HP, so buying means finding one used.
