The Tekton driver's aren't that cheap. They are actually pretty good and I find the arrangement clever enough. It is a little derivative from a lot of other ideas, but what a great way to get a coaxial mid-tweeter. If the arrangement controls the dispersion appropriately so listeners get similar effects to ESLs or horns without the downsides then more power to them.
I've never heard them, by the way, and I'm quite happy with my current set up. I'm just saying that this is an innovative and price appropriate design.
