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."

missioncoonery with all due respect you seem hell bent on finding negative things to say about Eric’s speakers. Why? If you don’t want to come out of pocket and try them for yourself then move on and enjoy what you have and leave this thread to those that have put up the money or at the very least have heard these speakers. Judging from the posters here and the amount of gear they have owned I find it difficult to believe these are a flash in the pan flavor of the day.

I don’t have a dog in this fight as I’m not an owner of Tekton speakers but I am mighty tempted to get the DI monitors after reading through the recent threads. Until that day comes I feel I have no right to comment on them good or bad and neither do you.
