The JBL Marine Series MS9520 6"x9" Coaxial Speakers are ready to take on anything Mother Nature throws your way. With Plus One woofers and balanced dome tweeters, you'll hear the clarity of your audio above the raucous sounds of the sea. Designed to take on the sun, sea spray and scrub downs, these powerful speakers feature waterproof motor structures, a one-piece cast-polymer basket, a sealed magnet, and rubber surrounds. Plus One Woofer Cones Plus One polypropylene cones provide more overall speaker-cone area than other cones in its class - the result is higher sensitivity, increased low- frequency output and greater musical character. Balanced Dome Tweeters deliver a smooth high-frequency response and increased power handling for highs and mids, which equates to more lifelike sound from vocals, cymbals, brass instruments and pianos. Rubber surrounds offer superior edge protection and are much more reliable than foam.
