Marine quality speakers should not do this. The real problem is caused from the boat cover leaking water in at the tower which flows down to the speaker area. Im working on a better way to seal off the tower area better. This is the first winter in 3 years the boat has been stored, never again. Pulling the boat back to Parker, AZ after Labor day for the winter.
Regardless of whether the housing is vented or sealed, there's no way moisture cracked that plastic. The only way water would have done that is if the whole thing was completely full and with a speaker cone that could move, it could never cause this. That's from stress, not moisture.
