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."

james, you have no idea what my "education" may be with this hobby. I suggest you read more of my posts than the last week to see what I’ve owned previously. Parasound Halo, Paradigm Signature, etc. In the last year I got bored with my systems and sold most of it off to experiment with what’s out there these days.

And I’m talking about the Enzo speaker, James. Not sure why I have to keep reminding you. Perhaps you should try some of your ineffectual fanboy attacks on the poster that posted the Enzo link, since he’s the one that brought the Enzo into the discussion. But it’s fair to discuss more than one model in a Tekton thread. Only a fanboy would cry foul.

It is indeed tired and dated, but fanboys attacking anybody that has a critical opinion of their speakers or other items has a long tradition on audio forums, unfortunately.  The first time I ran into this behaviour was on the Emotiva forum.  It was somewhat like a cult over there.  

Everything was fine while I was buying their products and reporting my joy, but as soon as I started finding the limits of their gear it was fanboy attack time.  I noticed others who had similar views might even disappear from the forum.  Ah well, hopefully Tekton can survive it if a small minority don't care for them.

213,
It's not the fact that you are criticizing them. It's the fact you are beating on them like they owe you money and you have never heard them or any other Tekton for that matter.
I am however getting somewhat of a kick from seeing what is gonna come out of your mouth next.

More to discover
