JL Audio M6-770ETXv3-Gw-C-3Gw is a 7.7" 2-way marine enclosed tower coaxial speaker system engineered for open-air listening on wake towers and arches. The long-excursion woofer and 1" silk-dome tweeter are housed in injection-molded marine enclosures designed to project clean, full-range sound well beyond the boat.
Each speaker is rated for 100 W RMS at a nominal 4 Ω load, with 91 dB sensitivity and a 45 Hz–25 kHz frequency response. When driven by a quality marine amplifier in the 40–200 W RMS per channel range, the system delivers midbass impact and high-frequency detail that remain intelligible in typical marine noise and wind conditions.
