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.

Hi lpretiring,

Do you know the specific drivers that Eric uses? It would be great to have a list for off the shelf replacements. Thanks!
I know Eric would use different tweeters and crossover components. One reason he stated was based on availability. I'm unclear on the history of the woofers. 
Perhaps someone else can chime in on early woofers in the D.I's.
Thanks, since the 5 year warranty will expire on mine in late November, I'm trying to be proactive in case of component failure.
Hi Tekton lovers,
I wanted to ask you for an advice.
I'm trying to build an hifi system around a pair of Double Impacts.
Going to order Don Sach's preamp and need your opinion on power amp: I'm between Audio Van Alstine Vision Set 400 and Pass Labs XA25.
I'd really want to buy a Pass' gear, since years. But can any of you mention if that would a good idea? The Impacts have good sensitivity, but they're massive and Eric mentioned they like power. The XA25 reaches 50W at 4ohm and can go to 200W A/B class into 2ohm. Do you think it's a good match? Any of you uses the Pass Labs XA25 with the DI's?
Thanks:)
@adversam I used my Pass XA 30.8 amp to power both the DIs and the DI-SEs. It was a good match and pairing. 

The XA 25 is an excellent choice.

The Van Alstine may also be a good choice, but I do not have direct experience with it.

All the best with your decisions and final choice.
