JL Audio M6-770ETXv3-Sb-S-GmTi 7.7" Marine Tower Coaxial Pair 100W 4Ω, 100W RMS 010-03279-00 (93656)

JL Audio M6-770ETXv3-Sb-S-GmTi is a 7.7" 2-way marine enclosed tower coaxial speaker system engineered for high-output, open-air marine audio on wakeboard towers and arches. The long-excursion woofer and 1" treated-silk dome tweeter are housed in injection-molded enclosures built to withstand saltwater, UV, and spray conditions common to marine environments. 

This system 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 paired with a quality marine amplifier in the 40–200 W RMS per channel range, it delivers clear midbass and detailed highs suited for open-air listening on towboats and performance boats.
