JL Audio M6 10-inch Marine Subwoofer – Gunmetal Sports Grille (4 Ω)

Massive Open-Air Bass. Stealthy Dark Aesthetics. No Enclosure Required.

Anchor your boat's soundstage with deep, hitting low-end frequencies and an aggressive, modern look. The JL Audio M6-10IB-S-Gm-4 is a flagship-grade 10-inch marine subwoofer purpose-engineered to add true sub-bass extension to your vessel without taking up valuable onboard storage space.

Ditching the traditional plain white marine look, this subwoofer features a bold, split-spoke Gunmetal Sports Grille. The dark metallic layout creates a premium custom accent that beautifully coordinates with modern carbon-fiber dashes, charcoal upholstery, and contemporary gelcoats.

As a dedicated Infinite Baffle (IB) driver, this subwoofer is optimized to run flawlessly without a custom enclosure box. Instead, it uses the large volume of open air inside your boat's fiberglass bulkheads, seat bases, or gunwales as a giant natural cabinet, saving you space, weight, and fabrication costs.

Key Features

• Premium Gunmetal Finish: The dark metallic multi-spoke sports grille strips away standard white marine styling, replacing it with a stealthy, custom performance accent that mirrors modern yacht interiors.

• Infinite Baffle (IB) Architecture: Engineered to thrive without a bulky sub box. Mount it directly into an open boat panel to experience deep, clean bass while saving your onboard storage space.

• Flagship M6 Excursion Performance: Built with a heavy-duty motor assembly and a high-excursion suspension layout. This 10-inch powerhouse pushes serious air to serve up deep bass that punches straight through high-speed wind, engine hum, and wave rumble.

• True Marine® Certified Construction: Fully armored against the elements. Utilizing advanced UV-resistant polymer baskets and synthetic fibers, the M6 line offers absolute defense against saltwater corrosion, moisture ingress, and intense sun exposure.
