Personally, I don't think I would be interested in that. If the VTF3 does what I've heard it does, that will be all the bass I'll ever need.

If it turns out I am dissatisfied, which I am 90% sure I won't be, I will return it and climb up the ladder to the EP500. I just wanted a sub better than my JBL. It appears that I have been successful in that endeavor. I considered SVS, but they just had too many choices to consider, and didn't have an 1-800 number to call, whereas the people at HSU were easily accessible, friendly, and answered my questions. The 50% off shipping for the holidays was really an added incentive which pushed me in that direction. Ordering the VTF3 vs waiting for HO models was a tough decision, though. I considered waiting, but then, I started thinking, that this sub has too be a little better than my son's PSB, which I actually like. In the end, the VTF3 became a no brainer and for less $ than I would have spent downtown. For now, I'll keep my fingers crossed.
