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."

Hi Mikirob,
You judge audio products by how they sound? Well so do I, Yes I understand that this is a strange and unconventional approach 😊
There’s an odd aspect of the High End audio community in that products can be looked down upon and dismissed "because "of their lower price.

There’s an ongoing thread that basically takes aim at Tekton Double Impacts and their owners. Essentially the premise is the speaker is "midlevel " quality and undeserving of the high attention level it has garnered. The OP of that thread hasn’t heard the Double Impact but deems it is not true High End caliber.

How one can glean so much information based on preformed assumptions is a mystery. There is a snooty snob attitude at work and this isn’t uncommon in the audiophile sector. Brand status and very high cost are required for approval or Acceptance.

Perhaps that OP and others of that mindset would find the Double Impacts unsuitable by their lofty standards, okay that’s fine. I'm a free market advocate and believe people can spend what ever they want, that’s their call.   My only point is to base an opinion on actual listening. I’ve heard very expensive speakers and some of them are truly superb sounding, yet still could be considered overpriced. This is subjective I freely acknowledge.

I do believe that higher price is actually viewed as a definite plus factor for a certain segment of audiophiles. That’s okay as there are always going to be distinct niches formed and individuals will decide where they fit in. My criteria is listen first and then offer a honest impression. Maybe Tekton's pricing model intimidates some, who knows.

Thanks to above respondents.  I would love to hear Tektons some day.  If anyone is in southcentral PA or thereabouts and would welcome a visit from a curious audiophile I would be most appreciative.

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
