The H-PAS demo got mentioned near the bottom of this Stereophile page , as well, plus a couple additional blog posts at Home Theater.

And another one , including a mention of the RR2150. I can't tell what the disc player is, though...

My knowledge of technical stuff is pretty limited, but because my NHT Classic Three speakers are also an acoustic suspension bookshelf design, the efficacy of this H-PAS technology makes some sense to me. The Classic Threes have measured down to 45Hz (+/- 3dB) using a 6.5" woofer. And yeah, they definitely sound great with my RR2150. Bravo, Peter. Looks like this development is about to take wings and fly.

This article goes into some depth on the H-PAS demos last weekend. It also mentions again that Outlaw is a licensee for the technology.
