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.

I’d seriously consider a used First Watt amplifier as a viable alternative if you’re adamant about only seeking a transistor amplifier. Nelson Pass design pure class A and ultra simple circuit. It has enough power for the Double Impacts.

I think that in terms of musicality  and natural high quality sound presentation  it may be superior to the other candidates mentioned, just my humble opinion.
Good luck ,,

I would 2nd the first watt as a very good choice,I have owned and or heard everyone of the except the sit 1 mono blocks.You might look for the J2,F3 and the F7 I think these would be outstanding driving the DI's.

I presently own a diy push pull sit that uses nos Sony Vfet's and I have a F7,but I haven't used it with the DI's yet.Maybe this week I will try it with my LTA MZ2 preamp.

One thing to consider is the first watt amps will hold their value better than most others.

Best of luck to you,

Kenny.

Kenny, I was interested in the reworking of your DI's.  In particular how you changed your woofers from the alphas to the betas.  On paper these are two different drivers.  I could see how the betas with their larger magnets might offer slightly more efficiency and tighter bass, but at the expense  of low end extension. The betas do have a slightly higher Fs as expected.
On a somewhat related note, how do these drivers achieve such low end extension when their resonant frequencies are in the low 50's?? They obviously extend well beyond that but I always read that Fs defines the low end extension and even in a reflex enclosure this seems way deeper than I would expect.  Any thoughts?
