7.7-inch (196 mm) Marine Coaxial Speakers, White Sport Grilles with RGB LED Lighting
M3 7.7-inch Marine Coaxial Speakers (70 W, 4 Ω) - Gloss White Sport Grille with RGB LED Illumination
Purpose-engineered and built for real marine duty, M3 coaxial systems deliver excellent performance at a more affordable price than our maximum-performance M6 models.
The oversized 7.7-inch design of the M3-770X results in increased efficiency (more output for a given amount of power). This gives them the ability to play louder and cleaner at high volumes than smaller speakers.
The woofer design is optimized to operate with a large volume of air behind it (at least 2 cu. ft. / 57 l). Operating this coaxial system in less space will compromise its low frequency performance.
A 0.75-inch pure silk dome tweeter, specially treated to withstand the marine environment, handles the high-frequency duties. Silk has been chosen for its lightness, excellent damping properties and smooth response characteristics.
Integrated into the Sport Grille’s frame, the internal LED lighting assembly was meticulously designed to uniformly illuminate the woofer’s cone area with a lively glow, adding a dramatic visual experience to your high seas journey. Add an optional RGB controller to create thousands of color variations. Professional installation is strongly recommended.
Although M3-770X Coaxial Systems can be used with as little as 20 W per channel, for best audio performance we recommend amplifiers capable of between 75-100 W of continuous power per channel.

Marine Materials / Testing
The design of marine products requires extensive materials testing to achieve reliability and longevity.
Building serious marine products requires a real commitment to environmental testing and materials specification. To this end, JL Audio has invested in Ultraviolet testing chambers (to simulate years of sun exposure) and Salt Fog chambers (to simulate years of exposure to salt-water environments). This testing is critical to building products that will not only sound great in your boat, but will also sound great for many, many years.
- injection-molded mica-filled polypropylene cone bodies with synthetic rubber surrounds, specifically formulated with UV inhibitors for marine duty.
- Marine-grade, synthetic fiber spiders with progressive roll designs to withstand high humidity.
- Specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer's motor system to prevent corrosion.
- Gold-plated, marine-grade brass connection terminals
- Marine-grade stainless steel mounting hardware is included.
