These 7.7-inch 2-way coaxial speakers feature durable construction.\n\u003c\/p\u003e\n\n\u003ch3\u003eAcoustic design and power handling\u003c\/h3\u003e\n\u003cp\u003e\n    With a nominal diameter of 196 mm (7.7 inches), these JL Audio speakers benefit from an oversized design, resulting in increased efficiency and improved mid-bass response compared to 6.5-inch models. Each speaker offers a continuous power handling (RMS) of 70 Watts and a peak musical power handling of 225 Watts. The nominal impedance is 4 ohms and the sensitivity reaches 90.5 dB at 1 W \/ 1 m. The frequency response extends from 45 Hz to 25 kHz (± 3 dB).\n\u003c\/p\u003e\n\u003cp\u003e\n    The woofer features an injection-molded polypropylene cone with mica fill, UV inhibitors, and a synthetic rubber surround. It is optimized for infinite baffle operation, requiring no dedicated enclosure. The 19 mm (0.75-inch) silk dome tweeter is equipped with a second-order high-pass filter and a semiconductor protection circuit. JL Audio’s DMA (Dynamic Motor Analysis) technology is integrated to optimize the motor’s dynamic behavior.\n\u003c\/p\u003e\n\n\u003ch3\u003eMarine durability and integrated lighting\u003c\/h3\u003e\n\u003cp\u003e\n    The marine-grade construction of the M3-770X-S-Gm uses materials resistant to corrosion and UV, exceeding industry standards for salt spray and ultraviolet exposure. UV- and corrosion-resistant polymer baskets and metallic gray Sport grilles complete the design. This model does not include integrated RGB LED lighting.\n\u003c\/p\u003e\n\n\u003ch3\u003eInstallation dimensions\u003c\/h3\u003e\n\u003cp\u003e\n    For installation, the required cutout diameter is 159 mm (6.25 inches). The mounting depth is approximately 80 to 84 mm (3.15 to 3.25 inches), and the outer frame diameter is 196 mm (7.70 inches). A minimum air volume of at least 57 liters (2 cubic feet) is recommended for optimal low-frequency performance.\n\u003c\/p\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":56076411994452,"sku":"010-03066-00","price":439.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_d4730662-a571-4e54-89dc-275e074dc30e.jpg?v=1781127094","url":"https:\/\/skysat.fr\/en\/products\/jl-audio-m3-770x-s-gm-flush-mount-marine-speakers-7-7-inches","provider":"Skysat","version":"1.0","type":"link"}
