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, you may not consider $9,000 speakers high end but many of us out there do. To each his own.

What do you have in your system?


Kenny,
I agree that the 800hz crossover point, along with the distance the woofer is away from the other drivers could be a bit of a problem. Maybe the low mounting of the 8" woofer was used to extend the lower frequency of that driver using the floor for some boundary reinforcement. The compromise, I would believe, be in the lower midrange. I couldn't imagine this speaker sounding anything like the DI's.....IMO

"I honestly would rather read a review on the Electron speaker and or the DI monitor speaker,that would be much closer to the DI's"

 I agree with you,lets see a review of these DIs in a stereo mag not some  home theater with all the specs fleshed out.Since we cant hear them without buying them seems that would be the way to go.Could and guessing would make us "30k killer" non believers shut up and go buy them.
