Tekton Double Impacts

@grannyring 
Ha! +1. I think the interest in these is incredible because the speakers are incredible!! 

   ...and I am working on adding a dedicated room in my basement first.

I'm full in with @mac48025 on this, too. Working the science of a dedicated room should do wonders. My only thing is, working on my dedicated room is talking FOREVER! - at least it feels that way. Of all things, the hold up is now the rug for the room. Without the rug, I can't match the colors for the walls. Without the wall color I can't match the color I need for some of the custom art panels.

I was hoping to be done by Christmas, but it doesn't look like it now. Boo! Hiss!

@grannyring  - I hear ya about the XOs. I mean, it HAS to sound better with upgrades all around. I'm not sure about replacing the woofers, but I'm certainly contemplating the internals in the near future.

I might consult with you. Is that cool?

Thanks Grannyring! Feel free to call to chat anytime too! The cool thing that often gets overlooked on threads like this is we’re all passionate about audio - every one of us. We all have so much more in common than differences.

That is so TRUE, Eric.

Great posts today.  Glad you are keeping in touch with our thread Eric.  I bought my DI's back early this year and verified I have an older crossover version.  So I do have interest in updating these at some time.  Maybe not to the degree/parts quality that Bill has done but I would like to incorporate the latest changes to this crossover.

Eric, it was good to hear you say what I suspected regarding the swapping of alpha for beta woofers.  Namely, the larger magnets afford more efficiency/heft in mid bass response at the expense of deep bass extension.  That is what I would have expected with my limited knowledge on speaker design basics.  (I recall someone stating there was "deeper" bass response with the betas.  I suspect they meant "more" bass in reality.)

Bill, I have read your post multiple times and looked at all your pics.  Your efforts here are really appreciated and I see myself taking on this project in steps.  Will start with the easy part--the woofer crossover and I will probably swap out the woofers.  In my room my DI's are very clean and a little more warmth in the midbass may be welcome.  I anticipate a pair of subs in the future so deep bass extension in not a concern.  I clearly will have questions for you in the future and thank you for any guidance you might provide.
