I bought a couple of speakers off ebay. Two styles as I do not know if either will last the distance.
The description to search for on ebay is:
57mm speaker waterproof
Step 1 is solder the wires onto the new speaker.
Step 2 is bend the wire like this so the seal will be to the black outer.
Step 3 Run the silicone around before putting the speaker in.
This silicone is a bit runny. It would be nice to have a more viscous sealant.
Step 4 a bit of extra silicone where the wire goes in
Unusual. Water got into this one.
Someone has done a replacement however they don't understand how the speaker works. The extra sealant stops the sound getting from the cone to the vent holes.
