With a 10-inch driver and classic white sport grille, the M310IBSGW4 delivers deep, clean bass and seamless integration into your marine audio setup. It's made to last in harsh marine conditions while offering a clean, stylish finish that complements white and neutral color schemes.

Whether you're streaming relaxing yacht rock or high-energy pop, the M310IB-S-Gw-4 responds with clarity and punch. Its rugged build and refined styling make it a favorite among boat owners who value both performance and design consistency in marine-grade components.

🌊 Built Tough for Marine Conditions

This subwoofer is built with marine-grade materials from the inside out. The sealed motor structure and corrosion-resistant polymer basket help it survive moisture, salt spray, and UV rays.

JL Audio designed it to meet ASTM B117 salt-fog and ASTM D4329 UV exposure standards. From freshwater lakes to saltwater coasts, it maintains long-lasting performance in marine environments.

🔧 Free-Air Installation for Flexibility

The infinite-baffle design allows this marine subwoofer to be mounted directly into your boat’s structure—like a seat base, helm, or rear wall—without the need for an enclosure.

It handles 175 watts of continuous power and has a 4-ohm impedance, making it a strong match for most marine amplifiers.

⚪ Classic White Sport Grille for a Clean Look

The white sport-style grille gives the M310IB-S-Gw-4 a clean and polished look that blends beautifully with boat interiors.

This UV-treated grille resists discoloration over time, so your system looks sharp even after years of exposure.

🧰 Easy to Install and Integrate

Because it doesn’t require an enclosure, this subwoofer is ideal for boats with limited space. Its 10-inch cutout size fits easily into many marine locations, and the free-air design simplifies the installation process.

Combine it with JL Audio’s marine-grade amplifiers for balanced, full-range sound throughout your vessel.
