@seanheis1 you mention the DI’s might not be ideal for midrange junkies and that they are for movies and music with slam.I suggest that you read again what I said. It was a Harbeth owner who found them too forward for his taste and had a challenge with the center image in his specific room. I hear the same thing a lot with the KEF LS50. Folks loving them at first and then eventually tiring over the forward image. We all have different tastes, rooms, and gear so I expect folks' mileage to vary and I like to hear folk's experiences, good or bad so thanks for sharing yours.
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 agree with the common sense approach of Swampwalker and Sebrof in regard to buyer paying for the return shipping cost of products auditioned in one’s home. I do believe that this would have the benefit of narrowing the field to those seriously considering purchase vs those who just want to hear them with no intention of buying. As was written earlier by bullitt5094 , the buyer should have some "skin in the game". Charles |
Without getting into the original arguments about comb filtering, this measurement of the Enzo XL from Stereophile implies Tekton is not above optimistically rating the sensitivity. JA measured 90 dB vs. specified 96. https://www.stereophile.com/content/tekton-design-enzo-xl-loudspeaker-measurements |
