JBL’s Stadium Marine loudspeakers leverage JBL’s world class audio engineering and music reproduction with purpose-built marine loudspeakers that will survive the rigors of the harsh marine environment. Choose from the most popular sizes for boats and watercraft. The 6-1/2" coaxial, 8" three-way convertible speaker system and 10" woofer have Plus One polypropylene woofer and midrange cones, Mylar tweeter domes (Except Subwoofer), one piece cast polymer baskets, sealed magnets, and rubber woofer surrounds for high SPL performance. Wind, water or engine noise will not drown them out. Speakers are UV resistant in a marine grade IPX3 (IPX5 from front) weather resistant and include RGB perimeter illumination and go through 300 hours of salt spray testing. And they’re ready to make amazing music on the water.

• Plus One Woofer Cones: Plus One cones provide more overall speaker-cone area than other cones in its class giving them higher sensitivity, increased low-frequency output and more distinguished musical character.
• SSI (Switch-Selectable Impedance): New Stadium Marine 10" (250mm) woofer features an exclusive dual impedance switch that lets you choose either 2- or 4-ohm load impedance option. SSI lets you reconfigure your system with the flip of a switch.
• Perimeter Illumination: Unique and eye-catching RGB illumination can display seven colors out of the box – or an almost unlimited number of colors when connected to an external lighting controller.
• One-piece Polymer basket: The polymer basket is durable over time even after prolonged exposure to sun, salt and moisture. Rubber surrounds are more reliable than foam and offer better edge protection.
• High Sensitivity: A high sensitivity rating combined with above-average continuous power handling makes it one of the loudest boat speakers available without sacrificing clarity, fullness and musical character.
