JL Audio M3 7.7-inch Marine Coaxial Speakers – Gunmetal Sports Grille (Pair)

Massive Acoustic Power. Stealthy, Modern Styling.

Command the waves with both sound and style. The JL Audio M3-770X-S-Gm speaker system packs the massive acoustic footprint of an oversized 7.7-inch format into a striking, contemporary Gunmetal finish.

If you are looking to move past traditional white boat speakers, these metallic, split-spoke sports grilles beautifully complement charcoal dashes, dark hull wraps, and modern grey vinyl interiors. Best of all, they back up their premium looks with incredible acoustic physics. The larger 7.7-inch cone surface area moves substantially more air than standard 6.5-inch models, delivering higher efficiency, louder performance, and a massive boost in deep, hard-hitting mid-bass.

Key Features

  • Oversized 7.7-inch Footprint: Moves significantly more air to deliver robust low-end bass and clear, loud audio that slices right through engine roar and wind noise at cruising speeds.

  • Premium Gunmetal Finish: The split-spoke sports grille sports a dark metallic gunmetal shade, offering a custom, high-end look for modern consoles, arches, and sports hulls.

  • Infinite Baffle Performance: Purpose-engineered to deliver deep bass without needing a dedicated enclosure. These speakers use the large volume of air inside your vessel’s bulkheads or gunwales to maximize acoustic energy.

  • Marine-Grade Silk Dome Tweeters: Outfitted with a treated 0.75-inch pure silk dome tweeter. It provides detailed, highly accurate high frequencies that sound smooth and fatigue-free, even during long days on the water.

  • True Marine® Certified Construction: Meticulously engineered from marine-grade materials to easily endure years of salt fog, pounding waves, high humidity, and intense UV exposure without fading or degrading.
