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."

Sorry about digression, but can someone explain comb filtering in layman's terms? I did read up a little about it but still can't "feel" what it means in terms of how it would affect the quality (or quantity) of the music reaching my ears.  Thanks.

After reading all these remarks about the Tekton speakers, I spent a good few minutes and browsed through their product line. On thing that stood out (for me) consistently across the board was the incredibly high efficiency/sensitivity rating of their speakers. Even accounting for the 4 ohm impedance rating  - less 3 dB as compared to 8 ohm, they are still rated in mid to high 90's dB/1w/1m - their largest tower model 1812 is 104dB. Someone used the word magic in crossover design and these values are pretty magical and might explain in part why these speakers sound the way they do. People might argue about how good they sound but there's no denying that a lot of thought and know how must have been put into the design of such crossovers. Many kudos to Eric.
I'm particularly intrigued by his OB open baffle model which doesn't seem to get much publicity.

Out of curiosity, those of you who ordered your DIs with upgrades but standard colors, how long did take to have them delivered?

Thank you guys. I see he has a few DI pairs listed under the "Specials", most with upgrades. I'm still baffled with how efficient these gentle giants are...

Kenny - They must sound incredible paired with your LTA gear.

missioncoonery, why the sour grapes man? The guy answered the question you asked. He bought something he liked but wanted to make it better. We all do that to everything we buy, to the extent our abilities allow. I bought a brand new Harley and the first thing I did was change the intake and the exhaust to make it "better".

What am I missing here?

I seriously doubt if any of the high end Italian speaker manufacturers with ultra exotic furniture grade cabinets allocate 40% of the cost in the drivers. If I remember correctly the norm is more like 10-20% depending on the specific model and its price point within the model line.

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?

"call a member of this forum a troll simply because hes not buying the BS Tekton is dishing is shamefull"

missioncoonery, shameful is with one l but that aside, whether you agree our not, you meet the troll criteria. Not because of expressing your opinion but because of the choice of tone and style. We can agree to disagree without bashing each other. I hope someone who really loves you surprises you by giving you a pair of Tekton DIs on your next birthday.
