2-Pair MS40B+2-Pair 40KMMTES BOAT

This compact marine tower package is designed for crisp, controlled sound on towers, roll bars, and rails. Four Rockville MS40B 4" marine speakers deliver surprisingly full audio from their injection-molded cones and ASV voice coils, tuned for outdoor listening. Aluminum MAC40B pods provide rugged, powder-coated housings with 360° swivel clamps that fit a range of tube sizes, suiting boats, UTVs, and carts. IP56 rating and marinized construction stand up to salt, spray, and UV. Together, these components create a stylish, high-efficiency tower setup that keeps playlists clear at cruising speeds.
