in al curved panels there are horizontal strips, (often transparant) without these the whole mylar would be almost flat. you can curve mylar by putting allot of tension vertical and almost no tension horizontal (or you would make it flat again ) and make the distance vertical where it is supported as small as possible. but it will never be perfectly curved.Unless the diaphragm actually stretches along the curve, then the whole thing is just moving back and forth perpendicular to the frame. Which then the curve would do zero for dispersion. I have always assumed this was a visual fake/cheat to give an impression of a curved wavefront launch. ?!?!?!?
