🔊 JL Audio M3-770X-SGWI Marine Speaker – Bright Sound Meets Vibrant Light
The JL Audio M3-770X-SGWI Marine Speaker deliver bold sound and customizable LED illumination in a stylish gunmetal sport grille. These 7.7-inch coaxial speakers offer increased cone area, allowing them to move more air than traditional 6.5-inch models. The result is louder, richer, and deeper audio ideal for open-air boating environments.
Built for marine use, these speakers combine top-tier components with visual flair. They're perfect for owners who want both performance and ambiance.
🌊 Rugged Marine-Grade Construction
Designed for harsh marine conditions, the M3-770X-SGWI uses materials that resist salt, water, and UV exposure. It meets ASTM B117 for salt-fog and ASTM D4329 for UV resistance. This ensures long-term reliability in sun-soaked or salt-heavy environments.
A polymer basket, sealed motor structure, and corrosion-resistant terminals protect the speaker from weather and wear. The LED lighting is also marine-rated, adding style without sacrificing durability.
These marine speakers are made to last season after season.
🔉 Enhanced Sound with Bigger Output
The larger 7.7-inch woofer cone moves more air, creating deeper midbass and cleaner vocals. Each speaker uses a 0.75-inch silk dome tweeter to deliver smooth, distortion-free highs.
Rated for 70 watts RMS and 225 watts peak, they offer plenty of volume for both quiet harbors and high-speed runs. Even without an amplifier, the M3-770X-SGWI delivers quality sound. Add a marine amp for more punch and coverage.
Music remains crisp and balanced no matter where you are on the boat.
🌈 Built-In RGB Illumination
Integrated RGB LEDs bring your sound system to life. These speakers glow with vibrant color through the grille. You can set a fixed color or use a controller (sold separately) to activate dynamic lighting effects.
Create the right mood for night cruises, parties, or relaxing at the dock. The lighting is subtle during the day but comes alive after dark.
This feature adds both functionality and visual impact to your boat’s sound setup.
⚙️ Easy Installation and Sporty Aesthetic
The M3-770X-SGWI fits standard 7.7-inch speaker cutouts. With shallow mounting depth, they install easily in most consoles, towers, or deck areas. JL Audio’s gunmetal Sport Grille adds a modern, edgy look that suits any style.
