Poly-Planar MS56 Box Subwoofer

The Poly-Planar MS56 Box Subwoofer is designed to provide the deep bass that serious anglers and boaters need for their marine audio systems. This compact subwoofer is built specifically for wet environments, making it ideal for installation in cabin, cockpit, or console spaces where traditional stereo speakers may not fit. Whether you're anchored for the evening or out on a long offshore trip, the quality of your music can significantly enhance your experience on the water.

Featuring a sealed box design, the MS56 effectively isolates the driver from marine vibrations and minimizes unwanted resonance, ensuring optimal sound quality even in tight quarters. Its marine-grade construction protects the internal components from salt spray, humidity, and thermal cycling, which guarantees reliable performance throughout the seasons. This subwoofer is lightweight at just 8 pounds, making it easy to install in various mounting locations.

Boaters looking to upgrade their stock audio systems will find the MS56's compact footprint advantageous, as it integrates seamlessly with existing Poly-Planar amplifier configurations. It pairs well with marine head units and powered amplifiers rated for 4-ohm loads, allowing users to enhance their audio experience without extensive modifications. For anglers who cherish their downtime, this subwoofer significantly improves cabin ambiance while at anchor or docked.
