I still don't see how the snail shell is any different than a well designed horn-loaded enclosure. Horns have the benefit of being able to basically tune themselves over a broader range than a regular ported box which tunes itself at one frequency. They are also generally many more dB efficient than a ported box. IMO they are more of a horn in nature than a TL but get that Wizard kid to admit that. Impossible.

^It strikes me the same way, as a clever horn loaded system. It's description is not unlike the B&W Nautilus... hopefully it works that well

Sure it can. A rear-loaded horn has a continuously expanding throat area that starts behind the woofer and extends to the outlet, usually of which is on the same plane as the speaker. A chamber is built behind the woofer, like a typical box, then a small throat lets the frequences out of that chamber to a mouth that is larger in area.

Here are some links:

I got lots more. Some really neat stuff out there. My theory is the powered4sound kid came upon one of these little-known designs and capitalized on it. Here ia a great diagram complete with dimensions:
