Cockpit speaker (VHF only)

[TiggerToo]

I need to replace Tigger's cockpit VHF cockpit speaker: does anyone here have any ideas/suggestions/recommendations. Sound quality is not an issue (i.e. no HiFi stuff) but resistance to seawater is - as is ruggedness.

I think ours is a Vtronix. It works and is probably >10 years old.
