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.

Joe, lancelock on this thread lives in Annapolis, owns DIs, and has ordered DI SEs. He has used all of the LTA tube amps, 10, 40, and new Ultralinear; Plinius, and Mirror Image SS amps @200WPC, so he can shed some light on the differences on amplification. Tekton did show with JC1s at 2017 RMAF to great effect, I'm sure they would be a worthy choice.
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 !!
