Poly Planar: Waterproof Marine Audio Built for the Open Water

Poly Planar has spent over 30 years engineering audio systems that don't just survive the marine environment — they thrive in it. Poly Planar is widely recognized as one of the world's leading designers and manufacturers of waterproof and corrosion-proof audio systems and outdoor speakers, purpose-built for marine, boating, pool, spa, patio, and outdoor applications. Whether you're outfitting a center console, a pontoon, or a backyard deck, Poly Planar takes an out-of-the-box design philosophy that results in products that look — and perform — unlike anything else on the market.

Marine-Quality Sound, Any Weather

At the heart of the Poly Planar lineup are its marine stereos, engineered from the ground up to handle salt air, spray, UV exposure, and the relentless vibration of a boat underway. These aren't car stereos in a weatherproof box — they're purpose-designed systems that pair seamlessly with Bluetooth-enabled devices, so boaters can stream their music, podcasts, and digital audio without compromise.

Complementing those head units is an extensive range of marine speakers and speakers in multiple form factors — from flush-mount round speakers and compact box speakers to gunwale-mount designs that tuck out of the way yet project full, rich sound across a deck. Many feature stainless steel grilles and fully waterproof cones, making them as durable as they are acoustically capable.

Complete System Accessories

A great audio system depends on more than just the speakers and head unit. Poly Planar's lineup of stereo and electronic accessories — including gasket-sealed radio splash covers — ensures your investment stays protected against water intrusion in even the harshest on-water conditions. These accessories are designed to work hand-in-glove with Poly Planar's core products for a fully integrated installation.

VHF Communication Solutions

Beyond entertainment audio, Poly Planar also manufactures a range of VHF external speakers and hailer horns. These thin, waterproof, dual-cone communications speakers are engineered to serve as extension speakers for onboard VHF radios, ensuring clear voice transmission can be heard anywhere on the vessel — a practical and safety-minded addition to any marine electronics setup.
