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."

Those speakers are just plain ugly, at least Bose had some fashion sense.  And being off on the sensitivity by one or two db's is acceptable.  6 is false advertising.  And the design is also a squarish box with several strong resonance peaks, so says stereophile's measurements.  

You can tell by the immediate personal attacks that my critique can't be debated.  Ugly.  False advertising.  Econo box performance.  At least you can pay extra to put a grill on that ugly mug.

@david_ten . Thanks! 

"then get jumped on for ruining them with crap cables or something." Kind of a joke. Throughout various threads, if not the Tektons in particular, there’s plenty of comments about gear that someone didn’t like or didn’t work out being met with comments about feeding crappy gear, having tin/stone ears, having crappy rooms, being trolls, etc. Maybe I spent too much time in the cable/fuse/tweak threads. :)

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.

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.

213runnin,

What does the Enzo Xl speaker have anything to do with the title of this thread.?

I personally have measured my DI speakers at 95.3 DB with a one watt input at 1 meter at the Industry standard frequency of 1K in my listening room.

I had 2 different pairs of Zu audio speakers in the past and I performed efficiency measurements on them in 2 completely different rooms and the end result was way less than the 101DB that Zu claims.

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.

Kenny.
