The Memphis MM603 marine speakers bring the proven performance of Memphis ATAC™ technology to a compact 6.5-inch format. Featuring a dual-tweeter ATAC array, the MM603 delivers wider sound dispersion, greater detail, and smoother frequency response than traditional coaxial marine speakers. The fully sealed waterproof design eliminates common water intrusion points while maximizing cone area for stronger midbass performance and exceptional clarity. Built with a marine-grade ASA composite basket, IP67-rated protection, and UV-tested durability, the MM603 is engineered to thrive in harsh freshwater and saltwater environments. Integrated RGB LED illumination in both the tweeter array and cone adds customizable style to match the premium performance. Whether cruising, fishing, or anchored at the sandbar, the MM603 delivers louder, clearer sound built for life on the water.
