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.

@kristofa Others that have the DIs should chime in as I am going off memory. Mine were not color coded. There was a + / - 'label' on the plastic housing around the binding posts. I would not describe the posts as dull copper, but they were not shiny either. Certainly NO oxidation. Hope that helps.
@kristofa
I have grills and experience no flakes on my speakers and on my head :)
I have the copper cardas binding posts...they are not shiny.

@kristofa:

The Cardas upgraded binding posts are copper with a + and - sign to indicate polarity. They tighten nicely with a wrench and hold the speaker cables securely. Being copper, they will always change color over time.

Have not had any paint flaking from the grills but suggest you contact Eric or Karma about this. The sound quality of Tektons is without reproach; the same cannot be said about his approach towards grills. I find this a minor issue and Eric was kind enough to send me two sets of grills because he knew my spaniels have a tendency to decorate large black boxes...

Thank you all for your input. I think I will certainly contact Eric and Karma about the paint issue. The flakes/chips line up perfectly with the grill staples holding the grill cloth. That is the culprit. 
@kristofa I have Tekton Double Impacts upgraded and my lacquer finish is also flaking behind the speaker grills and I can tell you why. Eric has used a spray adhesive to attach the speaker cloth and then staples. Nothing wrong with that except that the solvents in the adhesive are stronger than the solvents in the lacquer. Mine are flaking as well. Eric doesn't know that there would be a chemical reaction. He will now.
