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.

@charles1dad - This is a very robust power tube using very high voltages and requiring a very heavy voltage swing at it's grid to drive it. 30 watts is the absolute maximum this tube is capable of- and that's running it at it's absolute max specs (not a good recipe for reliability or distortion). The sweet spot for this tube is between 18-22 watts, and this amplifier will have fully user-adjustable bias controls to fine-tune the amount of current that it draws. 
Wow Grannyring, thank you for the post, what cables did you use? What gear did you use tubes or solid state? Can you mention the cd or sacd you played n vynil you played?thanks

Aric, 
Thanks,  the sweetspot operating point of a tube is where I want to be. 18 to 22 watts is far from stressing the 845 which is an additional advantage.
