all this affects the dispersion of the CLS speakers I suggest you
consider what happens to a diaphram that is fixed on it's parimeter

you

simple concept. Have fun figuring things out.

Regarding this "stretched diaphragm," how does this curved
diaphragm maintain its curved shape when stretched?
Boy oh boy, geometry wasn't your best subject either was it? Would you
ask the same question of a balloon as it is being blown up? How on
earth do they maintain their curved shapes while being stretched? It's
a mystery Howie, it's a mystery.
It is
attached at either side and one would think that unless it
was stretched fairly tight and pulled flat that it would
kind of sag in the middle.
Well, that would be quite a challenge now wouldn't it. I can't imagine
how Martin Logan pulls it off. Howie, maybe you should contenplate the
wonders and marvels of a tennis racket. How on earth do they keep that
open weave string from sagging in the middle?
Now, if the diaphragm is rather stiff that would allow it to
maintain its shape over that curved radius and no stretching
would be required. However, in that case it would have to be
fairly heavy, which would kind of run counter to the
low-mass requirements. And the stiffness would generate
resonances and also make it difficult for the thing to flex
at all.
OK you really are that stupid.
