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."

Interesting review. I was a bit taken back when the reviewer said that folks who like Harbeth, Audio Note, and Acoustic Vienna speakers would not find the Tekton Brilliance sound to their liking? I owned two of the three and loved them. Big fan of Harbeth in particular. I love how easy they are to listen to. Never aggressive or in your face. Always musical and composed. Audio Note speakers are also supremely musical.

What is is the point by the reviewer here? The Tekton design is not those things? It is much more lively and too pumped up for us Harbeth lovers? He also started the review with a big question mark that he really never sorted out well for us. The speaker went from sounding broken to amazing with no changes, burn in.......no real explanation other than his ears got used to them I suppose.

Then his friend really did not like the speakers from his initial listen and did not change his mind.

Contemplating the review one could easily, and reasonably, conclude that these speakers can be polarizing due to their additional brilliance and lively personality. Wonder how true this is for the DI? Love to hear more comments on this.

I least that that is how I read the review.

I guess I was confused.The Tekton website states their speakers are giant killers replacing 30k speakers .Im thinkiing Vivid ,TidaL,Lumenwhite,Kharma,Marten on and on.Even a poster here said he had 30k to spend and bought the DIs.....and now your saying these are midfi intended for home theater?
I don't know who called these midfi speakers, but that is a minority report if that is something from an owner. You really, really want to find fault with this product, don't you? I just can't figure out why that is.

"My guess is that the Brilliance is geared more towards 2 channel in a medium room and the DI is more geared towards larger rooms and home theater"...

LIghten up Bullitt,Im just asking is this what were are now discussing of have been . I was under the impression these speakers were giant killers replacing 30K speakers

Where in that quote do you come up with midfi? I use my DIs for HT & 2ch just as I used my B&W 804s for both HT and 2ch before the Tektons unseated them. I'm about to add Odyssey Candela pre and Kismet Reference power amp pieces to the same HT front end. The Candela allows a pass-through mode for HT applications. Best of both worlds. Using the Odyssey pieces in HT certainly doesn't make it midfi.
