JL Audio M3 Series 7.7" Marine Coaxial Speakers w/Grey Metallic Sport Grilles w/RGB LED Lighting - M3-770X-S-Gm-i [010-03067-00]

M3 Series 7.7" Marine Coaxial Speakers with Grey Metallic Sport Grilles with RGB LED Lighting - M3-770X-S-Gm-iPurpose-engineered and built for real marine duty, M3 coaxial systems deliver excellent performance at a more affordable price than our maximum-performance M6 models.The oversized 7.7-inch design of the M3-770X results in increased efficiency (more output for a given amount of power). This gives them the ability to play louder and cleaner at higher volumes than smaller speakers.The woofer design is optimized to operate with a large volume of air behind it (at least 2 cu. ft. / 57 l). Operating this coaxial system in less space will compromise its low-frequency performance.A 0.75-inch pure silk dome tweeter, specially treated to withstand the marine environment, handles the high-frequency duties. Silk has been chosen for its lightness, excellent damping properties, and smooth response characteristics.Integrated into the Sport Grille’s frame, the internal LED lighting assembly was meticulously designed to uniformly illuminate the woofer’s cone area with a lively glow, adding a dramatic visual experience to your high seas journey. Add an optional RGB controller to create thousands of color variations. Professional installation is strongly recommended.Although M3-770X Coaxial Systems can be used with as little as 20 W per channel, for best audio performance we recommend amplifiers capable of between 75-100 W of continuous power per channel.*Sold as a pairSpecifications: Continuous Power Handling (RMS): 70w Recommended Amplifier Power (RMS): 20 - 140w/ch System Efficiency: 90.5 dB @ 1 W / 1 m System Nominal Impedance: 4 ohm System Frequency Response: 45 Hz - 25 KHz ± 3 dB Specifications: LED Lighting: Yes Mounting Style: Surface QTY: Pair Size: 7.7" Watts RMS: 70w Box Dimensions: 5"H x 9"W x 17"L WT: 7.9 lbs UPC: 699440935210 Owner's Manual (pdf)
