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."

I think us Tekton owners should stop replying to these threads. It's obvious that the true purpose of them is to bash these speakers, regardless of their performance. These folks were never going to try them. The old saying is true, "there are none so blind as those who will not see".

david_ten,

Rest assured, If the DI's sound to me like the praise they have been getting, they will grace my living room for years to come...:)

333jeffery,

In my case, this is not true. As I said, I will give them a fair and impartial evaluation. I would do this for ANY loudspeaker system..... There are those who hear, but do not listen........

Jeffery,

I don't look at this thread as a bashing thread,

There has been some pertinent questions asked here,some may be not in the best fashion or intentions but IMO overall I think there is some knowledge to be gained.

As said from a couple of different professional reviewers the DI's are a very "Disruptive" product that is'nt going to be well received by many.

It is what it is.

Time will tell how this thread evolves.

Kenny.

I see the DI's as just getting started. Already there are upgraded crossovers and caps. There also appears to be quite a bit of room to upgrade the woofers and tweeters to higher end, such as from Seas or Dynaudio. And to solve any phase or comb filtering issues, DSP can be offered. Lots of potential. I love the efficiency.
