Tekton Double Impacts

Anybody out there heard these??

I have dedicated audio room 14.5x20.5x9 ft.  Currently have Marantz Reference CD/Intergrated paired to Magnepan 1.7's with REL T-7 subs.  For the vast majority of music I love this system.  The only nit pick is that it is lacking/limited in covering say below 35 hz or so.  For the first time actually buzzed the panel with an organ sacd. Bummer.  Thought of upgrading subs to rythmicks but then I will need to high pass the 1.7's.  Really don't want to deal with that approach.

Enter the Double Impacts.  Many interesting things here.  Would certainly have a different set of strengths here.  Dynamics, claimed bottom octave coverage in one package, suspect a good match to current electronics.

I've read all the threads here so we do not need to rehash that.  Just wondering if others out there have FIRST HAND experience with these or other Tekton speakers

Hey Kenny, I'm a little confused. Maybe you might be able to help me out, because I've seen different info here and there. 

Are the tweeters in the DIs Scanspeak or are they something else? 
The tweeters in the standard DI look like SB Acoustics but I could be wrong.

Kenny the amp is a KWI 200 integrated. Hopefully the Pass Labs will be a step up. The XA 30.8 will be the next purchase if the X 250.5 works out.
So, you didn't mod them, right, Kenny? Those are the tweets that came in them?
