In Reply to: I use diffraction rings posted by E-Stat on March 15, 2025 at 11:28:39:
I'd cut a rectangular hole with one dimension the driver diameter and the other bigger. A circle means you get all your diffraction at one frequency but the rectangle gives multiple lengths to the felt edge and you spread the diffraction at mutiple frequencies when it hits the felt edges. If you look at the felt around Wilson tweeters it's circular but evenly ragged to accomplish the same thing. But I wouldn't want to try to hand cut felt like Wilson.
