I have owned the Hsu VTF-2 for 20 some months, but only use it in my (low priority) 2.1 HT system. I have no strong opinions about it one way or the other (I'm a fan of transmission lines, but they can produce too much of a good thing if you don't bi-amp).BTW I've heard Hurdy Gurdy Dave's O.B. system (above) and it does many things very well, but as a single driver/simplier the better slanted kind of guy I'm "philosophically opposed" to the equalizer, bi-amping, and 4 woofers per side he's using to provide good bass from moderately sized open baffles.
