Hello all,
I am new to the forum here and I have my first question. I am curious as to if it would be possible to construct an ESL panel that is cylindrical. I have seen many designs for a curved panel but none that go the whole enchilada and curve into a cylinder. The major benefit, as I see it, would be an omnidirectional dispersion pattern. I am unaware, however, if this design is mechanically impossible or if there are any major negatives that would make it impractical to construct such a beast.

Can anyone chime in here with advice?

Thanks in advance!

Very interesting idea.
The first obstacle that comes to mind is the forces on the film it self.
If it moves "out" it will create a cylinder of a larger diameter and thus stretch.
I'm sure there's more physical constraints on this issue...

Didn't Sound Lab make a ROUND speaker that was an electrostatic?  But the lens or static panel was only on a 1/4 of the speaker.  Cannot remember the model but it was back in the 80's if I am not mistaken.
