JL Audio M6-770X-C-3Gw is a 7.7" 2-way marine coaxial speaker system designed for infinite-baffle installation in open-air boats. The long-excursion woofer and 1" treated-silk dome tweeter are engineered to deliver clear, full-range sound that cuts through wind, engine, and water noise in real-world marine environments.
Rated for 100 W RMS at a nominal 4 Ω load with 91 dB sensitivity and a 45–25,000 Hz frequency response, this M6 system works well with marine amplifiers in the 40–200 W RMS per channel range. The injection-molded, mica-filled polypropylene cone, synthetic rubber surround, polymer basket, and UV-resistant Classic grille support long-term reliability under salt, sun, and spray.
