JL Audio M6-770x-s-gmti M6 Marine Coaxial Speaker 93603

M6 7.7-inch Marine Coaxial Speakers for Infinite-Baffle Use (100 W, 4 Ω) - Gunmetal Trim Ring, Titanium Sport GrillePurpose-engineered and built for real marine duty, M6 coaxial systems deliver maximum audio performance in any open-air boating environment.The oversized 7.7-inch design of the M6-770X coaxial results in increased efficiency (more output for a given amount of power). Combine that advantage with long excursion and excellent power handling and you have a speaker system truly capable of playing loud and clear in a powerboat at speed.A 1-inch pure silk dome tweeter, specially treated to withstand the marine environment, handles the high-frequency duties. You will appreciate the clean, articulate high-frequency response of the M6 dome tweeter, especially at higher volume levels.A true 2-way passive crossover network is built into the terminal assembly to protect it from vibration and corrosion.Although M6-770X Coaxial Systems can be used with as little as 40 W per channel, for best audio performance we recommend amplifiers capable of between 40-200 W of continuous power per channel.Specifications:General Specifications:- Continuous Power Handling (RMS): 100 W - Recommended Amplifier Power (RMS): 40 - 200 W / Ch. - System Efficiency: 91.0 dB 1 W / 1 m - System Nominal Impedance: 4 Ω - System Frequency Response: 45 Hz - 25 KHz ± 3 dBCoaxial Physical Specifications:- Frame Outer Diameter (A): 7.70 in / 196 mm - Bolt Hole Circle Diameter (B): 6.92 in / 176 mm - Frontal Grille Protrusion* (C): 1.08 in. / 27 mm - Mounting Hole Diameter (D): 6.25 in / 159 mm - Mounting Depth (E): 3.32 in. / 84 mm
