From the owners manual:
"If you drop your speaker into a pool, unscrew the woofer and pull it out of the cabinet to drain the speaker. Reinstall the woofer and the speaker is ready for use again. The screened, angled port prevents water from entering the speaker under normal circumstances."
Well I am happy to report that they aren't lying. Had one near me as I was installing pavers around our new pool. My wife is doing some gardening, and decides to yank the garden hose without looking. Plop! The speaker goes straight into the drink. I fish it out by the still attached wire, and it is FULL of water. Follow the instructions. (allowing it to air out and dry overnight) No audible change. I love my Axiom's.
