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."

"with" not "wit" as above; must be a Freudian slip as I was thinking someone runnin' was perhaps, just might be a nit. Ok, I'll apologize now in advance, but I couldn't help thinking it. Best to you, happy listening...mikirob

Much, much, too much nincompoopery here and it is not from Eric Alexander or kdude66. I need to stop reading this particular thread. Best, mikirob

And the nincompoopery just keeps hitting the fan. Some folks are insufferable.

Thank you david_ten

Unfortunately, a "moderator" doesn't have a similar sense of humor or literary expertise and removed my Shakespearean post to another poster who I certainly deem as a damaging entity to a business based on baseless innuendo, lies, misbegotten misinformation, and other "crimes and misdemeanors." Yet, his foolish posts live. 

Something to to think about: when a poster makes outrageous claims against a product, business, unwarranted and not substantiated by facts, just comical BS, one needs to question the dogged attacks. Are they a rival business using Internet forums to sully a business rival? Are they the boyfriend of an ex-wife? Or any myriad of other illegitimate reasons. Most of the data in this thread by the dissenting minority is innuendo and fraudulent. There is also sidelong personal attracts against Eric Alexander, the designer of Tekton. The "moderator" should look at some of those crass attacks and gross disturbing distortions by some posters. Best, mikirob

Based on your logic wondering how Tekton DI only cost $3,000 retail, the opposite could also be true. Even if a speaker maker quadruple Tekton's cost internally, wire, capacitors, speakers and so forth, how does he justify a $30,000 to $50,000 price point? I have Devore 0/96 and Harbeth SHL5s. I bet their internals don't cost mega bucks more than the Tekton DIs. How do they justify their cost? Nice cabinetry? I judge everything in my system by how it sounds to my ears in my environment.

It must be difficult to be so in the dark about business models. If you think real hard perhaps, just maybe you can figure it out.

I'm always amazed when a company such as Tekton produces something worthy/significant at a reasonable cost and instead of accolades or a well done for their accomplishment they engender attacks, like in this thread. Extremely weird. mikirob

As always on Audiogon you are clarion bell of clarity, common sense, good manners as well as many other positive attributes. And, as such I fully endorse your words. I also deeply respect how you listen and evaluate products and music. You are honest and fair.

It sickens me in certain threads the stupidity expressed; the illegitimate ranting vitriol against a audio product a person or persons has never heard. For no sound reason these members create out of thin air, based on nothing, a negative bias. Not only that, in doing so these members insult the Audiogon members who have purchased the product and report good sound, reviewers, as well as the designer who has labored to design a worthy product. This is a shame. The "Moderator(s)" on Audiogon ought to be ashamed of themselves to allow unwarranted attacks of product not actually bought or listened too. Instead, they delete responses to the dogged attacks because???? Oh, you fed the dogs in kind their own nonsense. You were as harsh as they were. Best, mikirob

No. And no. No attack on DeVore or Harbeth. As charles1dad kindly stated it is a reasonable observation of many speakers internally. You might do your own investigation, you might be surprised in what you find out. Best, mikirob

And p.s., I very much enjoy both speakers. You're just picking a fight, injecting unwarranted out of context meaning as cmsgolf already rightfully pointed out. Again, research is your friend. Best, mikirob
