I build the 12" for my folks, and only had it in my place for a about 8 days. In my old room I couldn't get below 23 Hz response, but that, I'm sure had more to do with my room acoustics (it was 24 X 24 square) than the sub itself. Which is fine, my tested hearing doesn't pick up much below 22Hz.

My PW-2200 on the other hand cut out in the same room at 24 Hz, despite measurements to 19Hz or something.
At 1/2 the price it is far, far better.
To be honest, I owned the older Hsu Research VTF-2 model and it couldn't keep up with my PW-2200. I feel pretty confident extrapolating that the PE kit would destroy it.

I've ordered the 15" Titanic MKIII woofer and 1000 watt plate amp for the larger model (building a box myself to match the speakers I built), for the money, no commercial subwoofer, on-line retailer or B&M store, can come close.
For more measurements of actual in room performance, you should visit the PE forums. Lots testaments there from people who've owned the popular Hsu Research and SVS subs, Velodynes, Paradigm's, etc....

Good luck
