These 6.5-inch (165 mm) 2-way speakers feature a sport gray anthracite grille.\n\u003c\/p\u003e\n\n\u003ch3\u003eAcoustic design and performance\u003c\/h3\u003e\n\u003cp\u003e\n    These coaxial speakers integrate a 6.5-inch woofer with an injection-molded polypropylene cone filled with mica and UV inhibitors, paired with a synthetic rubber surround. The 0.75-inch (19 mm) tweeter is a pure silk dome, specifically treated for marine environments and using neodymium magnets for high efficiency. The long-excursion design, optimized by JL Audio’s DMA (Dynamic Motor Analysis) technology, enhances power output, bass extension, and power handling. The system is optimized for \"infinite-baffle\" operation, requiring a minimum air volume of 57 liters (2 cubic feet) for optimal low-frequency performance. A passive 2nd-order crossover for the tweeter includes a polyswitch semiconductor protection circuit.\n\u003c\/p\u003e\n\n\u003ch3\u003eTechnical specifications\u003c\/h3\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpeaker type:\u003c\/strong\u003e Marine 2-way 6.5-inch (165 mm) coaxial\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eContinuous power handling (RMS):\u003c\/strong\u003e 60 W per speaker (120 W per pair)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePeak music power handling:\u003c\/strong\u003e 225 W\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRecommended amplifier power (RMS):\u003c\/strong\u003e 20 to 125 W per channel (75-100 W per channel for optimal performance)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eImpedance:\u003c\/strong\u003e 4 ohms\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 55 - 25,000 Hz (55 Hz - 25 kHz ± 3 dB)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 89.5 dB @ 1 W \/ 1 m\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOutside frame diameter:\u003c\/strong\u003e 175 mm (6.90 inches)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCutout diameter:\u003c\/strong\u003e 127 to 133 mm (4.972 to 5.25 inches)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMounting depth:\u003c\/strong\u003e 69.5 to 72 mm (2.74 to 2.825 inches)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFront grille protrusion:\u003c\/strong\u003e 25 mm (0.973 inches)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBolt circle diameter:\u003c\/strong\u003e 155.5 mm (6.125 inches)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eMarine durability and installation\u003c\/h3\u003e\n\u003cp\u003e\n    These speakers exceed industry standards for salt fog and UV resistance. They feature UV- and corrosion-resistant polymer baskets and grilles, a saltwater-resistant polymer basket, and integrated marine-grade stainless steel grilles. The woofer cones include UV inhibitors and the spiders are made of marine-grade synthetic fiber. The design allows flexible \"free-air\" (infinite-baffle) installation without requiring dedicated enclosures. RGB LED lighting is available as an option, requiring separate 12 V wiring for each speaker and an RGB controller (sold separately). A 150 mA fuse on the positive LED wire is required for M3-650 and M3-770 models.\n\u003c\/p\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":56076403999060,"sku":"010-03061-00","price":324.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/01_71bddb1a-5ed4-417f-8f13-8e8441b8302e.jpg?v=1781126989","url":"https:\/\/skysat.fr\/en-us\/products\/jl-audio-m3-650x-s-gm-flush-mount-marine-speakers","provider":"Skysat","version":"1.0","type":"link"}
