A marine speaker is specially designed to withstand the action of marine agents, such as salt, humidity and high sun exposure.
The following are the measures that manufacturers normally use:
- The appropriate choice of cone material varies depending on whether it is a tweeter, midrange, woofer or subwoofer.
- Use of a reel unassailable by salt and humidity.
- Use of coatings that make them UV-resistant, to prevent a white speaker from becoming opaque in a short time or losing its molecular consistency prematurely.
- Equipped with stainless steel screws.
- Sometimes they are equipped with special grooves that allow the flow of water or condensed moisture.
When a marine speaker is not properly marinated it may be subject to the following issues:
- Rust stains under the speaker, caused by the screws or the coil, which force a constant cleaning of the boat in these areas.
- The materials that make up the cone slowly degrade.
- The performance in terms of audio quality is constantly and irreparably deteriorated, recommending the replacement of the speaker.
- The coating becomes opaque and the external grille can start to crumble.
