Marine speaker M3-770X-S-Gm

built-in

7.7-inch (196 mm) Marine Coaxial Speakers, Gray Metallic Sport Grilles M3 7.7-inch Marine Coaxial Speakers (70 W, 4 Ω) - Gray Metallic Sport Classic Grille Purpose-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 high 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. 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 pair.
