JL Audio M6 6.5-inch Marine Coaxial Speakers – Gunmetal Sports Grille with TransFlex™ RGB LED Lighting (Pair)

Flagship Audiophile Performance. Stealth Gunmetal Styling. Flawless Translucent Illumination.

Step up to the absolute peak of marine audio luxury and internal lighting technology. The JL Audio M6-650X-S-Gm-i speaker system represents the maximum-performance flagship line from the undisputed leaders in offshore sound. Meticulously engineered to deliver breathtaking acoustic fidelity at extreme volumes, this model enhances your vessel with a striking dark aesthetic and a stunning, built-in RGB LED visual display.

Unlike traditional marine speakers that simply throw light from behind the grille spokes, the M6 series features JL Audio’s patent-pending TransFlex™ RGB LED illumination. This advanced design embeds the LEDs directly within the speaker structure, channeling the light smoothly through a specially engineered translucent cone material. The result is a smooth, vibrant color field across the entire face of the speaker—completely free from hot spots, harsh reflections, or glares on the water.

Key Features

• Flagship M6 Reference Sound: Built with a massive, long-throw woofer and heavy-duty motor assembly. The M6 line handles more raw power and delivers superior mid-bass punch and vocal clarity compared to standard marine speakers.

• TransFlex™ Patent-Pending Illumination: Delivers unmatched evening ambiance by distributing vibrant, multi-color LED light smoothly across the entire speaker cone for a professional, custom-lit aesthetic.

• Modern Gunmetal Sports Grille: The dark metallic split-spoke sports design adds a high-end, custom look that beautifully accents contemporary sport hulls, wake boats, carbon-fiber dashes, and grey interior vinyl.

• Oversized Reference Silk Dome Tweeters: Equipped with a treated 0.80-inch pure silk dome tweeter. The natural lightness and damping properties of silk provide sharp, highly detailed high frequencies that remain ultra-clear at high volume without fatiguing your ears.

• True Marine® Certified Durability: Fully sealed from the inside out. Advanced UV-resistant polymer baskets, synthetic fiber spiders, and a completely enclosed internal crossover network provide absolute armor against saltwater corrosion, moisture ingress, and intense sun exposure.
