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."

There are several reviews falling into your lukewarm category including one person who returned the speakers not because he disliked them, but because they were not that much better than his current ones. Read through the extended threads and you will see.

As regards your comments that all posts are "fanboys or haters" this is the nature of modern day threads. When a product becomes popular, other competitors jump onto the thread and start posting degrading comment to try and boost their own products. On the AVSForum site there is a speaker builder who constantly derides the speaker then, as fast as possible, gets his website URL on the thread.

Others just want to post and show off their knowledge even though they know nothing about the product itself.

Why I bought the speakers, and what you need to know, is that those who do, UNIFORMLY say good things about the product. This is the bottom line.

AND, I refer you to my post above concerning "cheap speakers." There are no cheap speakers in the DI and those chosen are pro audio drivers of substantial ability. I would rather have these in my ongoing set than specialty items that cannot be purchased in case of need on the retail market. For 50 years I have been buying pro audio equipment and it is ALWAYS as good or better than home designs.
