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."

stfoth,

"I would expect if someone actually bought the Tektons and posted about them being the worst speakers the poster ever heard and such, that person would be "challenged" by others"

If you or anybody else actually bought and gave any Tekton speaker a honest shot and then decided they didn't like them for whatever reason and then utilized Eric's return policy,I would personally respect that persons decision because I know there is no perfect speaker,amp or other one piece of gear that every single person is going to like.

If you give me all details about what you are looking for in a speaker taking in consideration your room size,how close do you sit,music preferences,sonic preferences,volume levels,and other gear.
I probably could give you my opinion coming from experience of many yrs of listening to all kinds of gear.

@kdude66 Thanks.  Doesn't seem anyone who's actually bought them has completely trashed them, so that bridge may never be crossed, which is remarkable.  I think you suggested the Brilliance or Electron in another thread.

"Horrible small carpeted room, but thankful to be taking over the "guest room"--roughly 10.5' x 11' with 9' ceilings, so, of course, they'll be arguably too close to a wall with a listening position probably no further than 7-ish feet in the triangle. A closet can be opened behind the listening position, for whatever it might be worth. Most likely to be powered by PSETs at approximately 35 watts. A Rythmic sub can be used. General preferences are a laid back sound with good detail. Sensitivity to "shoutiness" and harsh highs (e.g., Klipsch HT tractrix horns as a personal no-go). As an example, primary speakers in other rooms are now Canton References and a recently acquired pair of Spendor s3/5r2."

Also have an Inspire 17w SEP that might be tried, but that's probably going in another room switching between Omegas and Princess Model 2s.

If Tektons work out, they will displace Salk HT3s to the "gym" (bedroom with some dumbbells and a treadmill that get not enough use, sadly) with solid state.  Not moving toobs to the "gym."  Makes me nervous enough in the "guest" room.

I'll try calling Tekton in next couple of days, but I suspect they might be busy working on the Super 1812 Double Mega Ulfs a couple of folks designed on the DI thread.  :)
The Mega’ s sound great!

Speakers are a very personal choice so it won’t take long to have others share their negative experiences. I just hope it is after spending time and not just a demo. No complaints here if someone doesn't like them after a long listen. I know it took me about a week to fully appreciate what I had. I recently invited a picky friend over fully expecting him to trash the DI’s and put me in check but it didn’t happen. Expect a smaller reviewer to get a pair soon and go against the grain for increased reputation/noterity. That or they genuinely won’t like them. IMO the greatest strength of the product is the value and the looks have really grown on me.

Insult an Audio Note product to a fan boy if you really want to deal with conflict.
stfoth,

Yes I did mention the Brilliance or Electron for you on another thread,

After reading your preferences and other info in your post,I'm going to recommend the Electron or the DI monitor on proper stands since you already have a sub.

Even though I have never heard the Brilliance,I don't think either one of us would like that one,It doesn't have the tweeter array that is the key to getting the detailed smooth,never in your face,magic of this design.
I believe either speaker would do just fine at 1 foot from the back wall and pointed straight ahead with no toe in needed.
These Tekton speakers are very forgiving in placement unlike most other speakers.They will sound nothing like the average kplisch horn speaker that you have to be 20ft away from to get coherent sound.

As you know I have the DI's and I normally sit 10ft away in a 20x25x9ft room that has our open kitchen on one side.I recently did a experiment and moved my speakers 1ft from back wall and I moved my listening chair to 7 ft from the speakers.The sound was just as good in this more nearfield listening position as I get at 10ft but I would be to close to my tv so it was just a experiment.
The DI's would be too big for your room I would think though,I haven't tried mine in my 2nd smaller system in a spare bedroom I'm more interested in the Electron or monitor for that room but I'm in no hurry.

Hopefully you could talk to Eric when he has a moment away from designing the "super 1812 triple mega Ulf's".

Best of luck to you,
Kenny.

You got that right +1.
