Rockville RM-PREMIUM-65 White 6.5-inch Marine Boat Speakers | 600W Peak, True Coax, 4-Ohm

All-terrain audio for vessels and outdoor adventures

Meet Rockville RM-PREMIUM-65, a 6.5-inch marine speaker pair designed for boats, ATVs, and UTVs. The true coax design places the tweeter separately from the woofer cone for improved imaging, helping highs and mids feel more defined across the listening area. Built to endure sun, spray, and the twists of outdoor use, these speakers blend rugged build with refined sound.

Each unit combines a robust set of components tuned for outdoor environments, with materials chosen to resist saltwater, UV exposure, and rough weather while still delivering clear, detailed sound. The result is a listening experience that remains expressive from cabin to cockpit or open cockpit while you enjoy your outdoor routines.
