A marine-grade 25cm subwoofer with thorough waterproof and anti-corrosion treatment. Black model compatible with Color Optix and built-in LED—delivering powerful deep bass over the water.
Rockford Fosgate’s M1 subwoofers are marine-grade subwoofers with thorough waterproofing and anti-corrosion treatment. The woofer unit uses a UV-coated PP cone and a TPE (thermoplastic elastomer) surround, so it can be used with confidence even in demanding marine environments with high humidity and intense UV exposure. The M1D4-10B is a 10-inch (25cm) 4Ω DVC model in black, delivering 300W RMS and up to 1200W maximum input.
