Engineered for the harshest marine environments, the M3-770X 7.7" Marine Coaxial Speakers deliver exceptional sound performance at a more affordable price than JL Audioâs high-end M6 models. The oversized 7.7-inch design enhances efficiency, allowing these speakers to produce louder, cleaner sound at higher volumes compared to smaller counterparts. With a woofer optimized for larger enclosures (at least 2 cu. ft. / 57 liters), these speakers ensure deep, rich low frequencies when installed in the right space. The 0.75-inch silk dome tweeter, treated for marine durability, provides smooth, detailed high frequencies. Designed to handle between 75-100W of continuous power per channel, the M3-770X speakers can operate with as little as 20W per channel for less demanding setups.• Amazing fidelity and affordability in marine settings• Exceeds international standards for salt fog and UV exposure• 2-Years Warranty• Sold as a pairSpecsContinuous Power Handling (RMS): 70wRecommended Amplifier Power (RMS): 20 - 140w/ chSystem Efficiency: 90.5 dB @ 1 W / 1 mSystem Nominal Impedance: 4 ohmSystem Frequency Response: 45 Hz - 25 KHz ± 3 dB 0.75" silk dome tweeter for smooth highs Power range: 20Wâ100W per channel Sold as a pair, marine-grade durability | M3 Series 7.7" Marine Coaxial Speakers w/ Grey Metallic Sport Grilles
