The JBL Club Marine MS65B is a 6.5-inch 2-way coaxial speaker designed specifically for the demanding environment of a boat or outdoor vehicle. Built to withstand the elements, it features a polypropylene cone and a rubber surround, paired with a sealed magnet to prevent moisture from compromising the internal components. This construction ensures a reliable audio experience with a frequency response ranging from 50 Hz to 20 kHz, while the IPX5 rating provides essential water resistance for the front-facing side of the unit. With a power handling of 75W RMS and a sensitivity of 92dB, these speakers deliver clear sound without requiring excessive amplification. Installation is straightforward thanks to a 5.06-inch cutout diameter and a shallow mounting depth of 2.81 inches, allowing them to fit into various marine compartments. To protect the hardware from salt and humidity, the unit uses corrosion-resistant materials. Each speaker comes with twist-lock grilles in both white and gray, allowing you to match the hardware to your vessel's interior aesthetic.
