I've read that somewhere also. No idea if 1/2 inch radius would be different than 3/4 for sound. I know I really like how mine sound though! I'm in the process of doing some room improvements with bass traps and wall pannels, should be even better when I'm done, sure blows the old B&W's I had away......oh, I also added 3 inches to the bottom of the speaker, didn't change the internal volume or dimmensions any, just wanted the tweeter to be a tad higher and below the ear.
