JL Audio M3-650x 65 Classic One Size

M3 Standard Flange 6.5-inch Marine Coaxial System (60 W, 4 Ω) - Gloss White Classic GrillePurpose-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 M3-650X 6.5-inch coaxial speaker is designed around the standard marine 6.5-inch speaker f... moreormat and features a wide mounting flange with a four hole mounting pattern. The long excursion woofer design and excellent power handling make your music come through loud and clear at speed, or at anchor. 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.Although M3-650X 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.Specifications:General Specifications:- Sold as a pair- Continuous Power Handling (RMS): 60 W - Recommended Amplifier Power (RMS): 20 - 120 W / Ch. - System Efficiency: 89.5 dB 1 W / 1 m - System Nominal Impedance: 4 Ω - System Frequency Response: 55 Hz - 25 KHz ± 3 dBCoaxial Physical Specifications:- Frame Outer Diameter (A): 6.90 in / 175 mm - Bolt Hole Circle Diameter (B): 6.125 in / 155.5 mm - Motor Outer Diameter (C): 3.85 in / 98 mm - Frontal Grille Protrusion* (D): 0.973 in / 25 mm - Mounting Hole Diameter (E): 5.00 - 5.25 in / 127 - 133 mm - Mounting Depth (F): 2.74 in / 69.5 mTECHNOLOGY:Materials Used:injection-molded mica-filled polypropylene cone bodies with synthetic rubber surrounds, specifically formulated with UV inhibitors for marine duty.Marine-grade, synthetic fiber spiders with progressive roll designs to withstand high humidity.Specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer´s motor system to prevent corrosion.Gold-plated, marine-grade brass connection terminalsMarine-grade stainless steel mounting hardware is included.
