Thanks clyde for that link.
There's a nice close up of that new planar, and the info seems to 'imply' that it runs 100Hz to 10kHz, but is augmented at the low end by those small dual mid cones and at the high end by a 1" tweeter (they call it a 'supertweeter' but seeing as it's -3db @ 25kHz it seem just like a conventional tweeter to me.
Seems like those planars would beam above ~4000Hz just based on their width, but guess I'd have to hear 'em to know for sure.
That's looks like a cool driver though... I'd like to know more about it.
They have little computer speaks too, and it's hard to tell, but it seems like those are much narrower in design, meaning I'm thinking they could run full range on the high end and not beam much or at all.
A long line of them would be killer mated to a nice bass cabinet to fill out the low end.
