Here is a post, copied fully, so we have the information to refer to.
This is from @wasson3 and is regarding the Tekton Design Ulfberth Be speakers. Thank you, Wasson3.
"Since I purchased the first pair of these speakers [Ulfberth Be] I would like to provide some information.
I first learned about Tekton back in December 2017 when I read about the DIs. I became very interested in the Ulfberhts still not knowing what to expect. I booked a flight to SLC and auditioned the speakers at Tekton’s company headquarters. I liked their sound but asked Eric if he was was willing to use upgraded drivers. He agreed on the satori be tweeters as the main upgrade and started building in January. They were delivered and set up last Wednesday.
To put my review into perspective: I am generally very skeptical about audiophile hyperbole. Reviews are often exaggerated and I was perfectly ok with a less than great sound. I looked at it as an experiment. I also have no problem (and often do) calling my own equipment mediocre if it indeed is. I don’t care if people don’t agree with me. There are more important things than a pair of speakers. I also have never posted on any forum and will probably never post again. I am only writing this to provide some information to people considering these speakers since mine are so far the only ones around as far as I know.
To summarize in one word, these speakers provide the most life like sound I have ever heard. They are transparent and crystal clear without being harsh. There is absolutely no comb filtering, something I was very concerned about since I like a wide open soundstage and don’t want to be limited to a ‘sweet spot’ for listening. They sit in a large 3000ft2 space and when first listening I always found myself looking back or into hallways or peripheral areas as you do automatically expecting to see somebody walking, rustling, breathing until I realized this was on the recording I was listening too. The sound is very 3-dimensional in a way I didn’t know was possible with 2 speakers. I am hearing details that I have never heard before. I am not sure why they sound the way they do. It may be the midrange tweeter hexagon arrays of 14 tweeters per speaker crossed for midrange or the upgrade to beryllium and low moving mass per driver or just the sum of all parts. I am not a speaker designer and don’t pretend to be.
I just wanted to give people who are thinking about these speakers some feedback.
They will certainly be the last speakers I will ever buy. I know there is owner bias and there are strong opinions about high end audio equipment, I can’t think of any other industry with more BS in marketing than high end audio. This all has to be considered when buying speakers.
Hope this helps."
