my own experience with Tekton Design

 I have owned a pair of double impacts for 3 years. I only listen to Rock and Roll, 85 to 90 db. and the DI's have been Great.

This might be why I didn't favor them. I like classical and jazz as well as rock, and typically listen around 80 db. 

@hilde45 - thanks for the info. I’m looking at Revival Atalante 3 and Fyne Audio F501SP. Both have received favorable reviews but I have been hearing so much about the Moabs I had to ask. Thanks, again. 

My Tekton experience. I stopped by Tekton unannounced on a vacation trip through Utah. Eric very graciously spent several hours with me discussing speaker design and several other subjects that we found we had in common. I also got a demonstration of the IRL system, INCREDIBLE!

On to the speakers. After talking several friends into trying out the Double Impacts and hearing them I decided I need to give Tekton a try myself. Yes, they still have their DI's. I ordered a pair of NEBO's with an AMT tweeter and ultimate crossover in a custom color my wife picked out. Would have loved to have one of his bigger offerings but I'd like to stay married. They sound fantastic as well as measure great to in my space. I listen to classical, jazz, jazz vocals, blues, rock and roll and some pop.

Room: 19' x 39' x rising ceiling from 12' to 18'

Here's what's in front of them. Amps:Atma-Sphere, Pass Labs XP-22, PS Audio Direct Stream (highly modified), Hermes DDC, Innuos Pulsar, NUCi7 running Roon ROCK, streaming Qobuz and local files. Also use Innuos Sense.

Bottom line, outstanding speakers at a great price from a very nice guy.

I have the moab be run with the michi m8 they are great he will put whatever crossover in it you want from modest to 2k upgrade.he is working, with ceramic speakers that have cone breakup>20 k so the human ear can hear the distortion above that hz.you can call him and tell him what you want he will guide you.they have alot of options .they don't look as good as my focal utopia be but there much less$ and to my old ears sound very close.both are run by same equipment michi m8 or sometimes mcintosh 1.2 k happy listening enjoy the music.

I have to admit my first exposure to Eric Alexander did not make for a positive impression. It was a video in which he explained the development of his patented tweeter array. He said he heard a 440Hz note played by a violin, and then measured the weight of the string the note was played on, which was 1/3 gram. He figured if he used a driver (or drivers) whose moving mass was no more than 1/3 gram to reproduce the sound of the violin, the reproduction would ipso facto surpass that possible from a driver(s) whose moving mass outweighed the violin string.

That’s one of the silliest things I’ve ever heard. First of all, if it’s a low mass driver you want, get an electrostatic. Then there is the fact that the weight of a violin string has NOTHING to do with how one goes about reproducing the sound it makes. It’s also inconsistent: Being a drummer himself, Eric surely knows that cymbals weight far more than 1/3 gram, yet produce very high frequency overtones.

Eric then said something which calls into question his technical knowledge: He stated that the first harmonic overtone of a 440Hz note is located at 880Hz, which is of course correct: 440 x 2. But he went on to say that the second harmonic is located at 1760Hz, which is incorrect. The correct number is 1320Hz: 440 x 3. Harmonic overtones are multiples of the fundamental note/frequency. Eric thinks the second harmonic is the first harmonic doubled. It ain’t!

Still, I would very much like to hear the Tekton line of loudspeakers. I’m a dipole planar man, but I’m open-minded.
