A different kind of driver... not your average 8" woofer.
The AS-190's arrived today as expected- boy, that was a heavy box! The magnets on these things look more like something you'd see on a 12" or even 15" sub driver.

The main spider is where you would expect it- it's a flat spider, looks like it should be fairly high linearity.
Behind the main diaphragm, which is driving by the large titanium voice coil, is a sort of inverted surround, attached at the edges, and seems to offer pretty good throw and centering also. you can just see it a bit looking at the upper right...

The pole piece vent is huge, following in the tradition of the other cell drivers, which attempt to lower the backside obscuring due to the magnet structure. OTOH, I'd say one would want to rebate this driver pretty much flush with the edge of the baffle, and take some care in relieving the inside mount on a thick baffle. I'm thinking the ideal thing might be two layers of Panzer Holz, then very little relief would be needed and it should be quite stout.
Talking about Panzer Holz is quite fun, as I'm about 3/4 of the way through "Wolfenstein: New World Order", which is a real hoot, and has a lot more heart and creativity than you usually see from that franchise- but then it was done by Machine Games, not ID.
