Marine 7" Component Silver Speakers

Alpine expands its line of performance Marine speakers with the SPR-M70 Type-R series component system designed for high-end boat sound systems. These speakers are built to handle a lot of power and still perform under harsh Marine environments. On top of that, they are extremely easy to install and provide an excellent sound upgrade to any boat. The SPR-M70 is built around an efficient titanium dome tweeter and 7” mid bass that provides clear, loud sound reproduction output in open-air environments. These speakers are designed to handle 75W RMS / 210W Peak power. Centrex grilles and high-strength, non-resonant, high-temperature ABS frames provide hard wearing durability.
