JL Audio M6 6.5-inch Marine Coaxial Speakers – Titanium Sport Grille (Pair)
Flagship Audiophile Sound. Cutting-Edge Titanium Styling.
Experience the peak of marine audio luxury with a bold, high-tech edge. The JL Audio M6-650X-S-GmTi speaker system delivers reference-grade, flagship sound quality wrapped in a striking Titanium Sport Grille. Purpose-engineered to produce breathtaking acoustic clarity at extreme volumes, this system is built for boaters who refuse to compromise on power or aesthetic presence.
Ditching traditional white grilles, the dual-tone titanium sports design features dark metallic spokes and a gunmetal frame. It beautifully accents modern carbon-fiber dashes, charcoal upholstery, and contemporary gelcoats, while delivering pristine audio that slices cleanly through high-speed wind, engine hum, and wave splash.
Key Features
-
Flagship M6 Reference Sound: Engineered with an advanced, long-throw woofer and heavy-duty motor assembly. The M6 line handles significantly more raw power than standard marine speakers, serving up superior mid-bass punch and unmatched vocal clarity.
-
Reference Silk Dome Tweeters: Outfitted with an oversized 0.80-inch pure silk dome tweeter treated to withstand harsh UV and salt-air environments. It delivers ultra-smooth, high-frequency definition that remains crystal-clear without causing ear fatigue over long days on the water.
-
True Marine® Certified Construction: Armored from the inside out. Advanced UV-resistant polymer baskets, synthetic fiber spiders, and a completely enclosed internal crossover network provide absolute defense against saltwater corrosion, moisture ingress, and heavy hull vibrations.
-
High-Tech Titanium Sport Design: The multi-spoke metallic titanium finish provides a sporty, custom look that elevates the appearance of wake towers, arches, bulkheads, and center consoles.
