JL AUDIO M3-650X-S-Gm 6.5″ Marine Coaxial Speakers, Gunmetal Sport Grilles

Purpose-engineered for real-world marine duty, M3-Series coaxial systems are built to deliver excellent sound in open-air boat environments, at a more affordable price.

The M3-650X 6.5-inch coaxial speaker is designed around the standard 6.5-inch marine speaker format with a frame design that is a direct fit replacement for most 6.5-inch marine speakers. The long excursion woofer design and excellent power handling ensures your music will play loud and clear at speed, or at anchor. Optimized for infinite-baffle operation, M3-650X woofers are designed to operate without needing an enclosure behind them. 

A 0.75-inch 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. A fixed grille-mounted design ensures peak tweeter performance with no loss of woofer radiating area. A 2nd order high-pass filter on each tweeter is integrated into the woofer grille and requires no additional mounting provision. Equipped with a self-resetting protection circuit, the signal going to the tweeter is monitored and automatically disconnected in the event of an overload to minimize the chances of tweeter failure.

While M3-650X Coaxial Systems can be used with as little as 20 W per channel, amplifiers capable of between 60-120 W of continuous power per channel are recommended for best audio performance. All JL Audio marine speakers are saltwater-rated, utilizing corrosion and UV resistant materials throughout to exceed industry standards.

Sold as a pair.
