Stereophile review of the $30,000 tekton speakers

As for using beryllium, that’s not new technology. Ushers had beryllium tweeters over 15 years ago and I didn’t buy them back then because of the tweeter

There’s just way too much hype continual hype around beryllium tweeters. It’s fairly easy to give yourself a headache listening to it, when implemented by many manufacturers.

Yamaha (the grandfather of it all..) wrote the book on beryllium tooling/fab/process dev back in the early 70s. They themselves have moved on from it and use Xylon these days (NS5000 family).

I wonder how much longer all the clingers will cling on to the rinse/repeat/rehash beryllium, as if it were the greatest thing since sliced bread...😒

Zylon is the new material that Yamaha uses, and it sounds incredible. Same physical characteristics as Be but I think not poisonous like Be. The 12-inch woofer on the NS5000 is made of Zylon as is the tweeter and the midrange. Yes, I have this speaker.

As the previous poster mentioned, it was Yamaha that first used Be in drivers for the NS 1000 in the 1970s. That was for the tweeter and midrange. Paradigm Persona duplicated the Be tweeter and midrange about 8 years ago.

@p05129  My neighbor purchased his YG Sonja 3s and I purchased a Von Schweikert VR9 SE MK2 98% for their sonic properties and 2% because they looked appropriate (great finishes, black-we like that, in our dedicated listening rooms and for the living room, NOT black, wood or white only). The big Tekton’s are okay but with a really plain appearance with a grill but yuk without them but that’s only my wife and my opinion. Lastly, I often listen in the dark, especially early evening to relax. With a system which maintains relative dynamics and all the color and dispersion at normal listening levels, it’s a pleasure to listen more quietly in the dark. 1. 2. & 3. okay!

The facts are some audiophiles want a fabric domed tweeter, some want a planar ribbon, and some want/love the sound of beryllium. We're into filling customers needs and we offer all options.  

Well this statement is a bit concerning. So with each driver change you also do the requisite reengineering often required? Doesnt inspire much confidence.
