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.

Finally getting around to upgrading from the DIs to the ulfberhts.  Just waiting on a call back from Eric when he has some free time to get the ball rolling.  One thing that I'm hoping, that this will possibly be the very last speaker upgrade for me in my lifetime.  Excited. 
As far as Amps go ,I am using the Rogue Audio St-100 with 1950s Mullard Long Plates in the 12AX7 positions ... Unreal Bass with liquid Mid range . Highly detailed , but not bright.
Purchased from Andy at Vintage Tube services. While not cheap, they are the best small signal tubes that I have heard . Andy’s description
" The warmest ,most liquid , but still detailed 12AX7 ever made ".
I believe it !!
Thank you, everyone on audiogon that viewed my listing I had 4,328 views in 12 days.
I now have my SE'S bandw2017ag has a very good pair of DIs and Ezra has his Ulfberhts
on order,Life is good everybody is happy.
So as a piggy back to earlier posts regarding whether to consider the DI's, or go all out on the SE's...I just popped the top on my newly delivered SE's earlier today. I am about 50 tracks into the audition/break-in and I can state without hesitation that, out of the box, the SE's have far bettered the DI's! Much more refined, transparent and dimensional than my broken in DI's! Coupled with the Aric Audio Motherlode, I am almost rendered speechless! I can only Imagine what the next few months have in store for me as each of them bloom and settle into their true character! 

Cheers to the talents of the small business audio geniuses!
