Detailed description
Detailed description
The JL Audio M3-650X-S-Gw-i flush-mount marine speakers are designed for demanding marine environments, delivering clear and powerful sound reproduction. These 6.5-inch (165 mm) coaxial speakers feature bright white sport grilles and RGB LED lighting, combining aesthetics with acoustic performance. They are specifically engineered to withstand marine conditions, including exposure to salt spray and UV rays.
Acoustic design and marine-grade robustness
The JL Audio M3-650X-S-Gw-i features a mica-filled polypropylene cone woofer with UV inhibitors and a synthetic rubber surround. Its long-throw design and DMA (Dynamic Motor Analysis) optimization enhance bass extension and power handling. The 0.75-inch (19 mm) pure silk dome tweeter, treated for marine environments, uses neodymium magnets and Ferrofluid cooling for sound clarity. These speakers have a sensitivity of 89.5 dB @ 1 W / 1 m and a frequency response of 55 Hz to 25 kHz ± 3 dB. They handle a continuous power of 60 W RMS and a peak power of 225 W. The nominal system impedance is 4 Ω, with a recommended amplifier power of 20 to 120 W per channel.
Integration and RGB LED lighting
Designed for free-air or infinite baffle installations, these speakers optimize performance with a minimum air volume of 57 liters behind the woofer. Their marine-grade construction exceeds industry standards for salt spray and UV resistance, with UV-stabilized polymer baskets and grilles, and encapsulated motor systems to prevent corrosion. The integrated RGB LED lighting in the grille illuminates the woofer cone. A separate 12 V wiring is required for the LEDs, and a 150 mA fuse per speaker is recommended. An optional RGB controller (sold separately) allows adjustable color control. The mounting is standard with a 156 mm cutout circle and a 5.00 to 5.25-inch (127 to 133 mm) diameter. The mounting depth is 2.78 inches (71 mm).
