In a way, comparing the ULS 15 and the VTF-15 is like comparing apples and oranges. The ULS is a sealed sub, while the VTF is ported and as such are designed with different goals in mind and will behave very differently in the same room.
Paul's statement around the quality of the VTF for HT was based on his view that a good HT sub performs well under the 20Hz mark. For various reasons, including room gain, the sealed ULS will, by Paul's definition, be a better HT sub. The VTF certainly does have more output overall, but not in the lowest octave. That doesn't make the VTF "bad" for HT, but just not as good as other subs in the comparison based on his measurements.
Here is the quote about the ULS from HSU's web site
"ULS offers outstanding performance with ultra low distortion and super deep bass extension". Also note that on HSU's site, the ULS is only down 1db at 15Hz vs. the VTF which is down 2db at 15Hz. Regardless of whether we believe these numbers to be accurate, even HSU's own published numbers support the statement that the ULS is a better HT sub (if sub 20Hz is the goal) than the VTF. You can take that up with HSU if you don't agree - it's their measurement.
Please read carefully and note that nowhere here or in any other post have I or others said that the VTF isn't a good sub, or isnt a good value. Just that there are other subs that are better performers down low, and if that is your primary goal, the VTF may not be the best solution. Whether it is better than more costly subs will depend on the sub. Is it better than some more expensive subs, probably. Is it better than a PB-13, Submersive, or many other more expensive subs - no, it is not unless (perhaps) cost is brought into the equation.
Just for the record, I have a JL F113, and there are AVS posters who don't think it's a good HT sub either. No big deal to me - it does what I want and fits the space/design criteria that I needed to fulfill. I don't let other's opinions bother me much when I'm happy with what I've got.
