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  (Snopto),
I'm certain that participants on this thread will appreciate your always thorough commentary as you describe your 2 power amplifier's sonic characteristics driving the Horning Eufrodite speakers.   Regarding the Line Stages I am looking forward to hearing the MZ2-S in my system.

Charles, Thank you for the explanation and specifics.

How would you predict the sonic outcomes (in differences) based on the 5 design differences you list?

Thanks.
@333jeffery  Thanks for posting the video. The clarity is so much better with this one and the sound as well. Those Carver (?) amps  look sweet...are you still using them or have the BHKs taken over? 

Look forward to hearing how the Allnic and BHK preamps compare!
@porscheracer  Any finalization on the preamp choice, now that you've received a number of suggestions?
@snopro   Thank you so much for your honest feedback on the MZ2S' performance for you. It's very helpful and I for one am glad you posted in the face of very strong support for this preamp in this thread.
