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.

@oorelli I'm working with a Schiit Saga, inclusive of both SS and Tube options; a modi DAC; a Cambridge transport; the NuForce STA200. If necessary, I can use my Marantz SR5013, which is how I work the HT. I talked to Eric about the amplifier and he said it would be fine, owing to how easily his speakers play. Nevertheless, I'm a little concerned, having heard the STA200 doesn't take a 4ohm load well... If I need to, as I mentioned, I can fall back to the Marantz, while looking for a new amp. If that happens, I might look to the Schiit Aegir, or perhaps Parasound, or anything else people recommend. 

In your view, Corelli, what disintinguishes the DI from the DI SE or the MOAB and do you think, given the room size of 12x14.5x(9'-11' at the midpoint), that I'm mostly involved with a head game, given that all of these speakers easily fill rooms four times as large as mine...? 
Eric has a video on YouTube saying basically big speakers in a small room is no problem. Not sure if you've seen it.

I'm not in a position to comment of the SE's or Moabs relative to the DI's.  I am sure they are all great speakers and huge values--especially the DI's and Moabs.  See the above link

Don't worry about your amp right now.  Sort out the speaker and placement.  Later you can decide what flavor amp you want.  Unlike many speakers, these speakers afford much more choice with almost any amp you might pick and they will clearly show the virtues or shortcomings of that design.
Quick Q:   I'm considering a used pair of DI's that are a few years old.   Has there  been any model, tweeter, or Woofer changes since the model came out that I should know about?

I think a couple of years ago Eric widened the sweet spot. Maybe you could get the SN and then call Tekton to see if you got the newer design?
