Tekton Double Impact & Comb Filtering

Like many of you, I have been pondering purchasing these speakers but am very curious about the unusual tweeter array. I asked the smartest speaker person that I know (he is a student of Sean Olive) about the design and below is what he had to say.   

"In theory it could work, but the driver spacing means that the crossover point would need to be very low.
He is using the SB acoustics tweeter which is 72mm in diameter, center to center on the outside opposing drivers is around 5.7 inches, which is about 2400Hz. This means that combing would stop between 1/4 to 1/2 of the wavelength (between 1200-600Hz) is where the outside tweeters should start playing nice with each other.
Since he is not using low enough crossover points he has created a comb filtering monster. Now while it's not the great point source that was promised, it's no worse than most line arrays and the combing will average itself out given enough listening distance.

The MTM spacing on the other hand is ridiculous. Hopefully he is cutting the top end off on one of those midrange drivers to avoid combing."

Probably not,
When I first called Eric I had read a little about the DI's and I put together a list of questions for him and that included detailed exact crossover points,So I could get a better understanding of the unusual and different design of this speaker.

He answered every one of my questions and after getting my DI's, I have confirmed that every detail that he told me is spot one.

When I read his patent that he has several times I found that to be kinda Vague and generic,so I really won't comment on that,Honestly don't really care.

Please, if you aren't serious about purchasing from him and are just looking for rocks to throw, don't call him. We, who await upgrades or shipments would rather have him working on our stuff. But if you're actually making a decision to buy, he will happily satisfy your need for information. Thank you!

Missioncoonery,

I believe you have every right to call Tekton and talk to Eric,
Maybe you will decide to buy yourself a pair and then you could give us your evaluation,good,bad,or ugly.

Out of curiosity, those of you who ordered your DIs with upgrades but standard colors, how long did take to have them delivered?
