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."

@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.
@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.  :)
