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

Pure Low-End Punch. Space-Saving Infinite Baffle Design. Flawless LED Ambiance.

Anchor your boat's soundstage with deep, tight bass. The JL Audio M6-8IB-S-GwGw-i-4 is a premium, flagship-grade 8-inch marine subwoofer purpose-engineered to deliver hard-hitting low-frequency extension without taking up valuable storage space on your vessel.

As an Infinite Baffle (IB) driver, this subwoofer is optimized to run seamlessly without a dedicated enclosure box. It uses the large volume of open air inside your boat's gunwales, bulkheads, or seat bases as a giant natural cabinet. When night falls, JL Audio’s patent-pending TransFlective™ RGB LED illumination steals the show. The lighting array reflects smoothly through the woofer cone material rather than shining raw bulbs directly into your eyes, casting a rich, uniform color field across your deck.

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.

• 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.

• Bold Sport Grille Aesthetic: The split-spoke Gloss White Sport Grille delivers an aggressive, modern look that beautifully matches contemporary sport arches, towers, and upscale hull lines.
