The quarter-elliptic shape of the corners is really good, IMHO better than the usual quarter-circle one. They are another solutions, too, even better maybe, but they are harder to define them for the numeric controlled machinery (they can be handcrafted, of course).

I really really encourage anyone using them to measure what they have in terms of Revelator and Illuminator drivers.

Best,

I suspect lower resolution measurements than Zaph or certainly SS do would appear smoother. But it's just beer goggles.

It depends. I took fairly high resolution measurements of the 18W revelators and they are far far better.

But as a result, I don't quite trust the SS FR response.

That and that the T/S parameters are often off too.

Do you have those measurements to share?
