Product details
Marine sound with Color Optix RGB
Open cockpits and dusty trails punish ordinary speakers. The M1-8B brings Rockford Fosgate’s M1 Color Optix line into a 8-inch 2-way coaxial rated at 150 watts RMS and 600 watts peak into 4 ohms. A 1-inch (25.4 mm) tweeter handles the highs through a 6 dB/octave high-pass, while midrange mounting depth is 3.3 inches (83.9 mm). Optically clear UV-stable RGB lighting encapsulation lets you match the speakers to your Color Optix controller.
VAST surround and sealed ICC network
VAST (Vertical Attach Surround Technique) increases effective radiating cone area by up to 25% compared with a conventional surround. The mineral-filled polypropylene cone is co-molded to the surround, backed by a linear synthetic fiber-blend spider. A fully sealed Integrated Concealed Crossover (ICC) keeps the network out of the weather, and zinc nickel-plated marine-grade brass terminals resist corrosion. Dual-function input terminals simplify wiring.
Pair them with a Color Optix controller
The M1-8B ships as a matched left/right pair. RGB lighting requires a compatible Rockford Fosgate Color Optix controller and wiring, sold separately. Confirm your amplifier can supply clean power near the 150-watt RMS rating, and use stainless or marine-grade fasteners in wet environments. Element Ready construction is built for UV, spray, and vibration—not a substitute for sealed mounting.
