Rockford Fosgate equips this M2 Series 8 Color-OptixT 2-way marine speaker with a laminated dome tweeter for full-hearted highs and polypropylene woofer for impactful lows. A built-in 12dB/octave crossover network, concealed inside the basket, keeps transitions smooth for a well-rounded, moving sound. Serial Numbers Are Recorded and Photographed Per Each Customer Order. Built-in illumination brings these speakers to life, and you can coordinate them with other Color OptixT speakers and subs using Rockford Fosgate’s Color OptixT Controller (not included) and RF Connect App. The rugged grilles can endure years in the sun and spray and still look great.
