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.

BTW.
I sent the link for the video to Eric, and ask him if that guy in the video was correct.
His reply was Yes.
He told me exactly what aniwolfe said
" Yip. And it’s far from necessary... only good for small rooms... and for DI speakers produced between June-October last year"
I think mine sound fine either way.It is just a matter of preference .
my room is pretty small.
I have the Lygndorf room correction which helps with the small room ,  tremendously.
My room is 34x24 with 10 foot ceilings. In my small room the 15 ohm parallel resistor was much preferred by my wife and I in blind testing. 
Bill,
You had also changed out your 6.5 inch drivers, and admittedly lost some deep bass in doing so,therefore, I can see why you would prefer them with the resistor.
Because of this ,they are not the same Double Impact speaker that the rest of us have .
Did I mention how much I love the sound of the LTA UltraLinear amp with my Double Impacts? I was going to write a review but a fellow Agoner beat me to it.
