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."

@kdude66 .  Thanks.  In your estimation, the latest magic is from the seven tweeter array?  I'm not sure how the vertical three tweeter are wired/crossed.  From the site, I thought maybe they were set up similarly, just with three.  Maybe that includes the Enzo 2.7.  A good question when I call.

@craigl59.  I've been using a couple panels from GIK, here and there, especially behind speakers and behind the listening position when either or both are "too close" to the wall.  I'm already pushing the WAF limits...  If I start putting pillows around, there will be blood.

Mofo, no I'm not off the measurement kick.  If a company can't be trusted to give accurate specs to their products, than I wouldn't trust them period.  Send them your wallet if you want, they are not for me.  

I am looking for an end game speaker, and the Sierra Tower is on the short list.  Ascend measures their products carefully, among the other things they do so well for the customer.  But I'll bow out as I've made my points for anyone looking for the pros and cons of speakers by Tekton.

@213runnin. I think specs should be accurate, too, and they certainly can give a basic idea of what's happening and whether the item may have issues in a system.  I also agree with the implication that a few folks made that a company that professes to have made everyone else obsolete might be rightly asked to "show me," even as many, many other companies do not.  Tekton, of course, doesn't have to any more than anyone else, and it's up to the consumer to decide, as you have, whether that's a deal-killer.

BUT, take a look at these, and, if you would, let me know what you think, particularly in relation to the frequency response spec v. the measurements.

Fraud?  Untrustworthy?  Measurements the end game?

I don't believe Canton published its own measurements.  These were and still are among the "best" speakers I've ever heard, although I admittedly don't make it a habit of auditioning $30k+ speakers.
