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.

Well, my DIs arrived today. However, the grills I ordered didn't make it and there appears to be no documentation. Before I hook 'em up, can someone tell me if the positive connection is on the left or right post when I'm facing the rear of the speaker. (or do these babies render polarity obsolete?). 

It's always the little things...
The plate the speaker binding posts are on has ’faint’ negative ( - ) and
positive ( + ) markings on each corner (top and bottom).

My two pairs had the ( + ) on the right side (all four speakers - looking directly at the rear of the speaker).

Shine a bright light on the plate, in case there isn’t sufficient natural light where you have them set up.
