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."

You think a non owner such as yourself spouting off about how ugly they are and measurements which you haven't seen and their appearantly Econobox performance which you just pulled out of thin air is helpful to anyone? Ohh and you've never heard them. You are trashing a mans bussiness and livelihood for no particular reason. I just don't get it. 
 Your baseless pointless posts should be taken into account more than a guy who owns them, has had them apart replacing components and basically knows them inside and out?

I didn't pull any of that out of thin air.  The measurements were done by Stereophile, and clearly show several cabinet resonance peaks, which Stereophile mentions.  These resonances are the result of a rectangle cabinet with sides that vibrate.  It would cost more for the manufacturer to properly brace the cabinet or use stiffer materials.  The link was provided above by another poster, obviously going over the measurements was too much for fanboys.

Also in the Stereophile review, they found that the sensitivity number provided by the manufacturer was off by 6db.  1 or 2 decibels might be understandable, but a variance of 6 is either an alarming lack of quality control or false advertising.  Fanboys might respond with silly insults, but it doesn't change the facts.  And they are indeed ugly, but I will allow as to how beauty is in the eye of the beholder.

Now which speakers are you referring too the double impacts or the enzo.

The title of this thread pertains to the double impact so your statements which I'm not disputing may be confusing to some readers.

Totem does not misrepresent their specs, not sure what you're talking about there, james.  That's my only point, which you can't refute.  Tekton is either flat wrong about the Enzo's sensitivity, or the quality control is badly lacking.  Either way it reflects badly on Tekton.  As does the many resonance issues with the cabinet.  Flame on, fanboy.
