JBL Club Marine Subwoofers are ready for your next outdoor adventure. These fully marinized speakers not only deliver JBL sound, they also provide RGB lighting to bring the sound to life. Engineered to withstand sun, salt, sea spray and wash downs, they feature sealed motor structures, UV resistant one-piece cast-polymer baskets, a sealed magnet and rubber surrounds. The polypropyelene cone and rubber surround provide great bass, and lots of output to ensure every note can be heard loud and clear. With two grille colors included in the box, you can easily match your speaker grilles with your boat.
