Hi Greg,

Sounds like it could work underwater.  How well might such a speaker project
sound in the air?  (I'd also like to broadcast while surfaced).  Sounds to
me like it would at least be muffled when used in the atmosphere; but do you
think it would be (almost) totally muted?

Thanks for the info; I think I'll experiment with this one myself.  I, too,
thought about pool speakers; can't find one around here so far; and I'm not
sure what the voltage might be.  Know anything about them?

VBR,

Pat
