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 has 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 the 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. Whether it’s a daily scrub down, a picnic in a quiet cove, or an all-out race across high swells, JBL has the right configuration for your craft.
