JL Audio M3 6.5-inch Marine Coaxial Speakers – Gunmetal Sports Grille (Pair)

Premium Marine Performance. Stealthy, High-End Aesthetic.

Give your boat a modern, custom look without sacrificing an ounce of acoustic quality. The JL Audio M3-650X-S-Gm speaker system pairs legendary crystal-clear audio with a striking, dark gunmetal finish. Designed to drop perfectly into standard 6.5-inch speaker cutouts, this system is the ideal upgrade for boaters who want to step away from traditional white speakers.

The multi-spoke, gunmetal sports grille adds an aggressive, athletic accent that beautifully complements carbon fiber dashes, grey vinyl interiors, or stealthy hull trim, all while delivering pristine sound that cuts cleanly through wind and water noise.

Key Features

• Sleek Gunmetal Finish: The dark gunmetal metallic sports grille delivers a sophisticated, high-performance look that sets your boat apart from standard factory white setups.

• True Marine® Certification: Engineered to face down the elements. Every component is meticulously sealed and built using marine-grade materials to defend against saltwater corrosion, yellowing from intense UV rays, and heavy vibrations.

• Smooth Silk Dome Tweeters: Equipped with a treated 0.75-inch pure silk dome tweeter. Silk is chosen for its lightweight properties and excellent damping, which provide crisp, highly detailed highs that never sound harsh or fatiguing at high volume.

• High-Excursion Woofer Engineering: A long-throw woofer configuration paired with excellent power handling ensures tight mid-bass response and clear, forward vocals over engine hum.

• Standard Drop-In Upgrade: Sized perfectly to fit standard 6.5-inch marine speaker mounting holes, making it a straightforward, hassle-free upgrade for your center console, side panels, or wake tower.
