They feature a mica-injected polypropylene woofer cone with UV inhibitors and a synthetic rubber surround, optimized for long excursion and infinite baffle operation. The 0.75-inch (19 mm) treated silk dome tweeter is specifically designed to withstand marine conditions.\n\u003c\/p\u003e\n\n\u003ch3\u003eMarine Audio Performance\u003c\/h3\u003e\n\u003cp\u003e\n    These speakers deliver a continuous power (RMS) of 70 Watts per speaker (140 Watts per pair) and a peak power of 225 Watts. The frequency response ranges from 45 Hz to 25 kHz (± 3 dB) with a system efficiency of 90.5 dB at 1W\/1m, ensuring detailed and powerful sound reproduction in open environments. The nominal impedance is 4 ohms, and the recommended amplifier power is 20 to 140 Watts RMS per channel.\n\u003c\/p\u003e\n\n\u003ch3\u003eDesign and Marine Durability\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003cstrong\u003eJL Audio M3-770X-C-Gw\u003c\/strong\u003e incorporate corrosion- and UV-resistant materials, exceeding industry standards for salt and sun exposure. Polymer baskets encapsulate the woofer motor system to prevent corrosion. Their oversized 7.7-inch design improves efficiency and mid-bass response compared to 6.5-inch models. The woofers are optimized to operate without a dedicated enclosure, though an air volume of at least 2 cubic feet is recommended for optimal performance. JL Audio’s Dynamic Motor Analysis (DMA) technology optimizes motor dynamic behavior for reduced distortion and better bass extension. The tweeter includes a self-resetting overload protection circuit. The cutout diameter is 6.25 inches (159 mm) with a mounting depth of 3.15 inches (80 mm). White \"Classic\" grilles are included. The M3 speakers are positioned to offer marine performance at a more accessible price than JL Audio’s M6 models.\n\u003c\/p\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":56076411011412,"sku":"010-03065-00","price":389.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_586c1136-6a35-44bd-a72a-42862d76fbd9.jpg?v=1781127074","url":"https:\/\/skysat.fr\/en\/products\/jl-audio-m3-770x-c-gw-flush-mount-marine-speakers","provider":"Skysat","version":"1.0","type":"link"}
