Detailed description
Detailed description
Designed for demanding marine environments, the JL Audio M6-770X-L-SbSb 7.7-inch (196 mm) flush-mount coaxial marine speaker delivers high-fidelity audio. This 2-way model features an injection-molded mica-filled polypropylene cone woofer with a synthetic rubber surround, optimized for long excursion and reduced distortion through DMA modeling.
Audio performance and design
The M6-770X-L-SbSb is equipped with a 1-inch (25 mm) treated silk dome tweeter with neodymium magnets and Ferrofluid cooling for improved response and power handling. It handles a continuous power (RMS) of 100 watts, with a recommended amplifier power of 40 to 200 watts per channel. The system’s nominal impedance is 4 ohms, and its efficiency reaches 91.0 dB at 1W/1m. The frequency response spans 45 Hz to 25 kHz ± 3 dB. A sophisticated 2-way crossover network, featuring 1st-order low-pass and 2nd-order high-pass circuits, is integrated into the woofer frame and protected against vibration and corrosion. It also includes an automatic polyswitch tweeter protection circuit.
Marine durability and installation
The JL Audio M6-770X-L-SbSb exceeds industry standards for salt fog and UV resistance. UV- and corrosion-resistant polymer baskets and grilles, along with encapsulated woofer motor systems, prevent corrosion in saltwater environments. The speaker is optimized for infinite baffle operation, requiring no dedicated enclosure. Its frame has an outer diameter of 9.13 inches (232 mm), a cutout diameter of 7.50 inches (191 mm), and a mounting depth of 4.26 inches (108 mm). The low-profile Luxe black grille, with a tweeter bridge and fine mesh, protrudes only 0.38 inches (10 mm), blending discreetly into marine installations. All M6 speakers are manufactured at JL Audio’s Miramar, Florida, facility using global components.
