Polyplanar MA-5500 Speaker

The Polyplanar MA-5500 Speaker is purpose-built for boaters who demand reliable audio in the harsh marine environment. After decades on the water, any experienced angler knows that standard consumer speakers fail quickly when exposed to salt spray, UV rays, and constant vibration. This speaker solves that problem by delivering robust sound output specifically engineered for the unique demands of saltwater and freshwater vessels, from center console fishing boats to cruising yachts.

Built with marine-grade materials and corrosion-resistant components, the Polyplanar MA-5500 resists the degradation that claims standard speakers within a single season. The speaker weighs 6 pounds, making it lightweight enough for flexible mounting on hardtops, rails, or cabin walls without straining boat structure. Its design prioritizes moisture protection and structural durability, with sealed enclosures and stainless hardware that won't rust or seize even after prolonged exposure to saltwater conditions.

Boaters upgrading existing marine audio systems or installing new stereo setups find the Polyplanar MA-5500 compatible with most standard marine amplifiers and head units currently in the market. Whether you're running a full-day tournament or weekend cruising, this speaker integrates seamlessly into OEM or aftermarket installations. Proper mounting in a dry location—above the waterline whenever possible—extends its service life and ensures years of trouble-free operation in demanding offshore and coastal environments.
