content: I purchased these speakers for my boat, and they started falling apart just as the warranty ran out. I used the boat very little and the stereo even less. They were not exposed to the weather because the boat is kept covered. I had Pioneer car NOT marine speakers with paper cones in the boat for 5 years. They were not weather resistant at all, but they lasted. The Sony speaker's claims to be UV and salt water resistant but the cones turned brown and bent out of shape. And the black foam around the cones looks like the glue is letting go. If you need a good set of speakers DO NOT BUY THESE. I did contact Sony and because the warranty expired 2 months ago they said they could do nothing.
