You have too much venom towards them for it not to be personal.
If I have a history here, don't just say it, prove it. I would not level that charge against you if I had nothing to back it up. If anyone had bothered to look, you would see that for awhile I was pretty enthusiastic about PSA's stuff when it was announced, especially when they released the first CEA numbers. This is a matter of record, you can go back and look it all up. But then the actual measurements came rolling in, it wasn't bad but it wasn't great either. And then I saw how it managed to accomplish relatively little with a large driver and 500 watt amp when I saw the actual naked driver being used, it made sense. Even then, I didn't really start objecting to PSA subs until their fans started ripping on all the competitors subs by pointing to a poor interpretation of CEA measurements. This is all a matter of public record, all of this stuff is still out there, it's easy to look up. Go look at my posts when their subs were first announced, go look at my posts when the first review came out at Audioholics, and look past that. Its easy to do if you limit searches by date, user, and word criteria. Don't just blithely accuse me of bias, there is a body of record to prove or disprove your assumptions, and it is just a finger touch away from you.

I have decided to get the VX-15 based on the DATABASS numbers. My calculations derived from DATABASS indicate that this is the best bang for the buck for under $800 shipped. At current prices, I can also say the same for Rythmik FV15HP at $1412 shipped and LFM-1EX at $599 shipped.
I have found that if I were to go for Hsu VTF-15H instead, I would be spending 16% more only to get 6% more performance. This is not worth it IMO.
I believe the PSA's chart is erroneously showing VX-15 a better subwoofer than VTF-15H. I found the chart not very tasteful.
On the other hand, according to DATABASS, at their respective price points, PSA VX-15 appears to be using a better driver than Hsu Research's VTF-15H.
If all you care about is generalized CEA numbers, you have a good analysis. But just try comparing their compression, distortion, group delay, and waterfall decay times. This neatly illustrates my complaint about using CEA numbers alone to asses a sub's performance, and these kind of over-simplified comparisons are what PSA banks on. The VTF15h isn't using a great driver, but it is much superior to the XV15 because it doesn't need equalization to hold its response, it doesn't distort as badly when stressed, and it manages to stay cleaner at higher output levels than the XV15 can achieve, all while using less wattage. Look past simple CEA numbers, they only tell one part of the story with respect to performance.
