I have an older VTF Mk3. Great sub, but the amps suck and mine died within 5 years and it might get used every other weekend for a movie. I had to buy a replacement and it cost me a fortune, and the sub never sounded the same again. I went SVS subs the last time around, their vinyl finish is garbage with it bubbling and peeling within months on both subs, and the sub is good but not a good as the HSU. I have a EP500 on the way now, granted it's a V3, we'll see how it compares.
Down firing subs are a pain in the butt on carpet.
