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

Thanks.

What are y'alls consensus too Pre, Amp, and Dac synergy choices with the DI SE's?  Feel free to chime in with what you appreciated the most in the combo. 

Wow... I haven't been on this thread for more than a year when I had the mini Ulfs on order. Anyone that bought a set have anything to say about them vs the DIs?
I just finally ended up buying a set of speakers and they are being built and can't wait to get them.

I do not know about the SE bout i have the DI with the upgraded cardas copper post and the upgraded coil. I can tell you that they sound like whatever you feed them.I can easily hear any equipment change or cable changes very easily .
Would you guys think it'd be a waste to connect DI SEs directly to an av receiver? Or would using the avr pre outs to a power amp and then the DIs be a whole lot better?

Also, for HT setup, anyone tried the DI centers? 
Not at all.  Depends on how far you want to push performance to meet your needs and preferences.
