Tekton Open Baffle Speakers

I see they have new open baffle speakers with 15 inch woofers that can be pre-ordered for 3000 bucks.  After the pre-order period they will be 7K.

Has anyone heard a prototype of this speaker?  At this price point it's tempting to order and sell if I don't like it.  I have 4 two channel systems and a vibrant stereo kit graveyard.
