Ulfberht’s Available In Soft Gloss…

Posted in Uncategorized on May 29, 2018 by tektondesign


We now have soft-gloss black Ulfberht PMD’s finished and ready to ship for $9K per pair delivered.
The patented Ulfberht is flat-out one of the best sounding loudspeakers ever devised and Ron Cook at Stereo Times says: “If you are shopping for a loudspeaker that delivers the performance of the Ulfberhts and you don’t buy them – be prepared to shop in the six-figure price range. They are THAT good! 
The patented Tekton Design Ulfberht is our ‘flagship’ model designed to be produced and sold in large numbers over being overpriced and admired by few. I can assure you the Ulf will not be too big for your room either; the Ulf is a large format loudspeaker (big in size) with low frequency optimization producing spectacular results in the average sized room. In other words… It’s not going to acoustically overload your 14’x 16′ room, it’s going to sound magical!

Double Impact Review

Posted in Uncategorized on March 20, 2017 by tektondesign

“With his patented design, Alexander has brought to market one of the greatest musical speakers that you can purchase regardless of price–yet he’s offering it for an unbelievably reasonable price. HomeTheaterReview.com publisher Jerry Del Colliano gave me an excellent term to describe the Double Impact Speaker: he refers to such a component as a “disruptive product” in that it so radically snaps the ratio of cost to performance that it skews the market to the point that it would be irrational to spend a lot of money for far less performance.” – Terry London

Forthcoming Double Impact Professional Review by Terry London

Posted in Uncategorized on February 6, 2017 by tektondesign

We’re thrilled to have the first pair of Double Impacts on deck for professional review and scrutiny. Terry has been kind enough to share a few images of his setup and provide initial impressions:

“Eric had communicated with me his excitement/joy for the last year and a half regarding his new revolutionary speaker design, he was waiting for his U.S. patent to be approved, that he was starting to build into his speaker models. He sent me for review a pair of standard Double Impacts, $3,000.00, and I have to share that with first listening session I was patently shocked at the performance of this speaker! The Double Impact Speakers were not just great for the money or price point, they are world class reference level speakers, regardless of price! I have had as my reference speaker for over five years a highly regarded $19,000.00 transducer that was outperformed by the Double Impacts in all important sonic parameters. The Double Impact Speakers are amazing at creating the illusion of real music with all the purity of the colors of instruments, space/air, and the “pop” and dynamics that you find in live music.”  -Terry London
