     OK there is talk about the flat sides flexing I can go along with
that idea but now what if the sides where bent in eight equal sections
to form the circle that would cut down on big flat surfaces and would
keep it from flexing due to the small area. Any one have any ideas on
that system.

I have no engineering input on the side flexing or corner fatiguing
aspects, but from an acoustic standpoint I suspect a *7* sided circle
would be better than an *8* sided one (or any other even number).
