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."

213runnin,

you have never heard them. Econobox performance. Please! That's why there is a Tekton thread with 2K posts within a couple months. They must really suck. You just sound stupid. 
I also see you have a pair of Totem Rainmakers. They must blow away those crappy ole Tektons! Wanna talk about bad measurements! Only someone who doesn't care about measurements would buy them so I am a little confused?
 The DIs measure very flat in my room btw. Flatter then KEF 201/2 which is known to be a poster child for accuracy. You have no idea if the DI has comb filtering and I am doubtful you understand it. 
So your off of the measurement kick now that you've been called out? 
No one ever said they were pretty. I think they look pretty obnoxious but sure as hell don't sound like econo box speakers. But hey if form over function is your thing ... 
You think a non owner such as yourself spouting off about how ugly they are and measurements which you haven't seen and their appearantly Econobox performance which you just pulled out of thin air is helpful to anyone? Ohh and you've never heard them. You are trashing a mans bussiness and livelihood for no particular reason. I just don't get it. 
 Your baseless pointless posts should be taken into account more than a guy who owns them, has had them apart replacing components and basically knows them inside and out?
213,
It's not the fact that you are criticizing them. It's the fact you are beating on them like they owe you money and you have never heard them or any other Tekton for that matter.
I am however getting somewhat of a kick from seeing what is gonna come out of your mouth next.

213,
Ok this is the last time I'll respond. Your latest post looks like you are trying to say you are being bullied for giving opinions on the speakers. Here are excerpts from a few of your posts... Need a hanky?

"A noisy square box with low budget drivers, what an awful design that they are charging way too much for."

" Econo box performance.  At least you can pay extra to put a grill on that ugly mug."

  "But I'll bow out as I've made my points for anyone looking for the pros and cons of speakers by Tekton." (this did not happen)

 

The comb filtering thing is ridiculous in a modern speaker.   $3000 is a complete rip off, but Bose sold junk to suckers for many years before people got wise to those little cube home theater nonsense speakers.  (you are assuming they have an issue with comb filtering, again never heard them)

 

“I expect in a couple of years, unless Tekton gets serious about speaker design, the latest flavor of the month will be up for sale in the used marketplace in droves.   Too bad that marketing and the lemming instincts of the internet herd can cause such a waste of money.” (so you are basically calling anyone that likes Tektons a Lemming / Sucker?)

 

This doesn't exactly feel like constructive criticism to me. If you heard them pretty sure you would change your tune but the fact that you haven't and are making such bullish claims tends to get on peoples nerves.

 

 

Stupid is as stupid does .. does anybody have a box of chocolates??? Jenaaae. 
Tektons are like a box of chocolates.. until you try them you never know what ure gonna get.
csmgolf was only pointing out that your rainmakers measure worse than the Enzo which is not even the speaker being discussed here.Totem's specs state +/- 3 db which is not even close to what Stereophile measured. I don't really see that as over the top defensiveness nor an attack against your rainmakers. He doesn't even own Tektons and said he didn't really care for the ones he did hear all that much. 
213runnin,

uhh yeah you were directing it directly at csmgolf.  Did you read your own post? I get the feeling you have never been wrong! Must be a wonderful feeling being so enlightened. For you to spend so much time on Tekton threads runnin your mouth about things you know nothing about is very comical, ridiculous, and ignorant. 
213,
I am not at all surprised that you did not respond to csm's well written logical post.
213, 
that was really clever how you engaged about the bose patent and acted like you were interested in it so you could compare it to 
Tekton. sneaky sneaky. Hahahahahhahha
213 
would you like me to copy and paste every unwarranted slanderous thing you have said again? 
You are speculating that the only way this can be done is with a integrated single driver. I had the LS50's big brother 201/2 for several years.
