These 2-way speakers are optimized for outdoor use, ensuring clear and powerful sound reproduction on the water. They combine a continuous power rating of 70 watts RMS with a peak music power output of 225 watts, providing dynamic sound even at high volumes. Their Gunmetal-colored \"Sport\" grilles feature integrated RGB LED lighting for customizable onboard lighting ambiance.\n\u003c\/p\u003e\n\n\u003ch3\u003eRobust and Durable Marine Design\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003cstrong\u003eJL Audio M3-770X-S-Gm-i\u003c\/strong\u003e marine speakers are engineered to withstand harsh marine conditions. Their construction exceeds industry standards for salt fog and UV exposure resistance, making them impervious to seawater and corrosion. The UV- and corrosion-resistant polymer woofer baskets encapsulate the motor systems for enhanced corrosion protection. The injection-molded polypropylene woofer, filled with mica and UV inhibitors, is paired with a synthetic rubber surround. The 0.75-inch (3\/4\") silk dome tweeter delivers detailed high-frequency reproduction.\n\u003c\/p\u003e\n\n\u003ch3\u003eAudio Performance and Integration\u003c\/h3\u003e\n\u003cp\u003e\n    With a nominal impedance of 4 ohms and an efficiency of 90.5 dB at 1 W\/1 m, these speakers deliver an extended frequency response from 45 Hz to 25 kHz (± 3 dB). The 7.7-inch size provides improved efficiency and mid-bass response compared to 6.5-inch marine speakers. The woofers are optimized using JL Audio’s proprietary DMA (Dynamic Motor Analysis) technology, reducing distortion and enhancing transient performance and bass quality. An integrated 2nd-order passive crossover for the tweeters, featuring a semiconductor protection circuit, manages frequency distribution. Designed for infinite baffle applications, they require a minimum air volume of 57 liters (2 cubic feet) for optimal performance.\n\u003c\/p\u003e\n\n\u003ch3\u003eIntegrated RGB LED Lighting\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003cstrong\u003eM3-770X-S-Gm-i\u003c\/strong\u003e speakers feature built-in multicolor RGB LED lighting integrated into the grilles. This requires a separate 12 V wiring harness for each speaker. Up to seven fixed LED colors can be wired directly. For adjustable and extended color control, an external RGB lighting controller (sold separately, such as the JL Audio MLC-RW) is required. A 150 mA inline fast-blow fuse must be installed on the positive LED wire for each speaker to protect the LEDs and speaker from excessive electrical current.\n\u003c\/p\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":56076412256596,"sku":"010-03067-00","price":472.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_954cdbbd-75ac-4461-a989-32bbd3280b7b.jpg?v=1781127115","url":"https:\/\/skysat.fr\/en-us\/products\/jl-audio-m3-770x-s-gm-i-led-flush-mount-marine-speakers","provider":"Skysat","version":"1.0","type":"link"}
