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

So far they sound good . I cannot make a judgement yet.
Its really funny that they sound more similar to the speakers i had there, than they  sound differently. I still need more time on them .Only 20 hrs or so for now. 
I had the Source Technology 2268 but upgraded the mid drivers  to the  SEAS Excel W18EX-001 (E0017) 7" magnesium Cone Woofer.
from the SEAS Prestige ER18RNX (H1456) 7" Reed Paper Cone Woofer  
"what about red?"

She wanted me to get Double Impacts and the Mini Ulfs in red but I had concerns. They look great in red so she was right. It’s her birthday today, maybe I should order her Impact Monitors in red as a gift ;)
tfoth, I've had my listening position as close as 6' from the DI's with very good results. My DI's are 6' apart and I now have my listening position about 8' away. The DI's allow for a lot of latitude with regards to positioning, room size and listening position
I Cannot remember where i got the info but, the distance that your speakers are apart , center to center Multiplied by a factor of 1.3 to 1.4 equals the ideal listening distance from the speakers.
I think mine are 79 inches apart and my listening position is about 103 inches from left speaker  to listening  position and 105 inches  from the right speaker to the listening position.
 The math says that it should be 102.7 to 110.6 inches
