These resilient marine speakers are specifically designed and built to last in harsh marine environments. Injection-molded polypropylene cones and rubber surrounds increase the speakers' longevity and help make them more resistant to moisture and heat. All exposed speaker elements are carefully injection-molded using high-temperature ultraviolet resistant resin, preventing them from breaking down in the sun and giving you peace of mind to enjoy your music on the water even during the sunniest days. These IPX5 rated speakers are built to stand up to wet, corrosive conditions and are highly UV resistant. They feature an injection molded polypropylene woofer cone with rubber surround and a 1/2" PEI dome tweeter. They offer 2-way full-range sound for impeccable audio playback with 480W Peak for the pair.
