Purpose-engineered and built for real marine duty, JL Audio M3 coaxial systems deliver excellent performance, while priced for any boat on the water. The JL Audio M3 marine speakers feature a long excursion woofer design and a 0.75-inch silk dome tweeter to handle the high-frequency duties. Integrated into the speaker 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. The JL Audio M3 Coaxial Systems are efficient enough to be used with as little as 20 watts per channel – a typical radio with built-in amplifier, but for the best audio performance it is recommend to pair with amplifiers capable of 75-100 watts of power per channel. The JL Audio M3 speakers are also available with a classic grille design as well as a larger 7.7-inch speaker and a gunmetal color.
