Poly Planar Speakers: Built for Life on the Water
When it comes to audio equipment that can truly survive the marine environment, few names carry the weight of Poly Planar. As a long-standing innovator in waterproof and corrosion-proof audio, Poly Planar has spent decades engineering speakers specifically for the punishing conditions found on boats, docks, and open water — where salt spray, UV exposure, and constant vibration quickly destroy ordinary audio gear.
What Sets Poly Planar Speakers Apart
One of Poly Planar's most distinctive engineering achievements in the speaker category is their ultra-low magnetic field technology. Recognizing that conventional boat speaker magnets affect compasses and autopilots, Poly Planar developed a family of ultra-low magnetic field marine speakers, with exclusive technology that allows you to locate speakers wherever you want without interfering with navigation instruments. This is a critical advantage on any vessel where instrument accuracy can be a matter of safety.
Poly Planar speakers are also engineered from the ground up for durability. Stainless steel grills, polypropylene cones, mylar tweeters, and plastic frames ensure their marine and outdoor speakers provide years of listening pleasure. Easy to install and packaged with stainless steel hardware, Poly Planar waterproof boat speakers are precision designed and built with components that can withstand the punishing marine and outdoor environments.
Speaker Lines & Product Range
Poly Planar's speaker lineup spans a wide range of sizes and configurations to suit virtually any installation. The MA Series covers 2-way coaxial flush-mount speakers in popular sizes — including a premier 5-inch model and a 6.5-inch 2-way marine speaker, both featuring an upgraded waterproof design and supplied with both white and graphite gray grills. For tight spaces, the subcompact box speaker series is designed to fit in difficult locations while still delivering high-quality sound.
For those who want premium performance with added style, the Ocean Series brings both sound and light to the cockpit. The Ocean Series high-performance speakers surround a boat with clear, crisp sound and cool blue light, featuring IPX6 waterproof rating, rugged construction resistant to sun, salt, and corrosion, and an independently-mounted crossover circuit.
Poly Planar also addresses marine communications with dedicated VHF extension speakers. These completely waterproof and corrosion-proof communication speakers feature stainless steel grills, polypropylene speaker cones, and Teflon-coated wires, making them reliable companions for any onboard radio setup.
For full-range sound in an oval format, Poly Planar's 6" x 9" premium oval marine speakers are medium-powered three-way designs engineered for full-range sound capability. And for boaters with jet skis, inflatables, or tenders, amplifier kits with included waterproof speakers are designed to deliver crisp, clear stereo sound on smaller watercraft where space is at a premium.
