JL Audio M6 8-inch Marine Subwoofer – Titanium Sport Grille with TransFlective™ RGB LED Lighting (4 Ω)

Pure Flagship Bass. Space-Saving Infinite Baffle Design. High-Tech Titanium Styling.

Anchor your vessel's audio environment with deep, tight low-end frequencies. The JL Audio M6-8IB-S-GmTi-i-4 is a premium, flagship-grade 8-inch marine subwoofer purpose-engineered to add rich, hitting bass to your boat without taking up valuable onboard storage space.

As an Infinite Baffle (IB) driver, this subwoofer is optimized to run flawlessly without a dedicated speaker enclosure box. Instead, it uses the large volume of open air inside your boat's bulkheads, seat bases, or gunwales as a giant natural cabinet. Ditching traditional white styling, the dual-tone Titanium Sport Grille features dark metallic spokes and a gunmetal frame that seamlessly complements modern grey upholstery, carbon-fiber dash layouts, and contemporary gelcoats.

When the sun goes down, JL Audio’s patent-pending TransFlective™ RGB LED illumination steals the show. The lighting array reflects smoothly through the translucent woofer cone material rather than shining raw bulbs directly into your eyes, casting a rich, uniform color field across your deck with zero harsh glares.

Key Features

• Infinite Baffle (IB) Optimization: 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.

• High-Tech Titanium Sport Look: The dual-tone metallic titanium finish provides a sporty, custom look that elevates the appearance of modern center consoles, sports hulls, and luxury cruisers.

• TransFlective™ RGB LED Illumination: Uses a patent-pending design that embeds multi-color lighting inside the housing, emitting a smooth, vibrant glow across the entire translucent cone face with zero harsh glares or blind spots.

• Flagship M6 Excursion Performance: Built with a heavy-duty motor assembly and a high-excursion suspension system, allowing this 8-inch driver to push serious air and deliver tight, deep bass that cuts cleanly through wind and engine roar.

• True Marine® Certified Armor: Meticulously engineered from marine-grade polymer baskets and synthetic fibers. The M6 line provides absolute resistance to saltwater corrosion, relentless UV yellowing, and constant rough-sea vibrations.
