The sound of the sea could use an upgrade. The new JBL Marine Series 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. Harman's patented 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. Weather resistant 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. 

Their one-piece polymer basket is designed to stand the test of time, even after prolonged exposure to the sun and salt. Rubber surrounds offer superior edge protection and are much more reliable than foam. And a grille-mounted tweeter allows the front of the woofer cone to be sealed, protecting the motor structure from sea spray. For most brands, off-the-shelf speakers and a cursory approved frequency response curves are good enough. That's not the case with JBL. JBL does not only listen to their speakers against the competition, they voice them against each other to ensure each line has a consistent JBL sound signature that's known and sought out by those who care about their audio. This is just part of an extensive development process undertaken by some of the best transducer engineers in the world to provide the finest listening experience at any price point. 

JBL tested every speaker design to rigid specifications, subjecting them to extreme conditions that would break lesser speakers, this is ideal for equipment that will be heavily driven in the elements. JBL freezes them, bakes them, shakes them, blasts them, with ultraviolet light and drives them to full power for days to make sure your audio investment lasts for years. These 6.5" (16.5 cm) coaxial two-way speakers have a sensitivity of 90dB, nominal impedance of 4 ohms, a frequency response of 50Hz 20kHz, a peak power handling of 180 watts with a continues average of 60 watts. The speaker mounting depth is 2-13/16" (70 mm) with a mounting cutout diameter of 5-1/16" (128mm). Included with the speakers are speaker wire, stainless steel mounting hardware and an owner's manual.
