JL Audio M6 6.5-inch Marine Coaxial Speakers – Gloss White Sport Grille (Pair)
Flagship Audiophile Sound. Modern Sport Styling. Built for the Open Sea.
Step up to the absolute peak of marine audio engineering. The JL Audio M6-650X-S-GwGw speaker system represents the pinnacle of offshore sound, meticulously designed to deliver reference-grade audio fidelity at extreme volume levels. Purpose-built for the brutal realities of the marine environment, the M6 series is the choice for boaters who refuse to compromise on clarity or power.
Featuring standard drop-in 6.5-inch fitment, this model swaps out tired factory speakers and wraps them in a bold, split-spoke Gloss White Sport Grille. They provide a high-performance visual edge to modern center consoles, wake towers, and sport arches while effortlessly slicing through high-speed wind, engine roar, and crashing waves.
Key Features
-
Flagship M6 Performance: Engineered with an advanced, long-throw woofer and a heavy-duty motor assembly. The M6 line handles significantly more raw power than the entry-level M3 series, unlocking superior mid-bass punch and unmatched vocal clarity.
-
Reference-Quality Silk Dome Tweeters: Outfitted with an oversized 0.80-inch pure silk dome tweeter treated specifically to withstand harsh UV and marine conditions. It produces silky-smooth, highly accurate high frequencies that stay crystal-clear even when pushed hard.
-
True Marine® Certification: Armored from the inside out. Using advanced UV-resistant polymer baskets, synthetic fiber spiders, and a fully sealed internal crossover network, the M6 line offers absolute protection against saltwater corrosion, humidity, and intense sun exposure.
-
Athletic Sport Styling: The clean Gloss White Sport Grille features a modern, aggressive multi-spoke design that perfectly matches contemporary hull aesthetics and high-end boat interiors.
