I'm very uneasy about speakers whose position or orientation is not fixed.
They can seriously derange a magnetic compass.
I'd much prefer that speakers be in a fixed location and orientation. None
within several feet of the compass.

Sorry, I lost the thread to a "view," but Radio Shack on-line has a $20
extension speaker

For "waterproof," stick it in a big baggie.
