6 1/2” Coaxial 2-Way Marine Silver Speaker System

The new SPS-M601 Silver 6.5” Type-S 2-Way Coaxial speakers allow you to enjoy the premium and powerful sound Alpine is renowned for, out on the open water. Specifically designed for both fresh and saltwater environments, these IPx5 water-resistant speakers are ready to cut through the wind, waves and motor noise as soon as you are. 7/8” Titanium/PEI balanced-dome tweeters deliver accurate and crisp high-frequency detail whilst the accompanying super-stiff 6.5” poly woofers handle the mid-range frequencies.

On the exterior these innovative Marine specific speakers represent the highest in environmental resistance. Their sleek non-resonant, high-strength, UV-resistant grilles protect from yellowing; whilst their high-temperature ABS custom frames provide more than enough strength for any kind of mounting required. Santoprene® rubber surrounds offer high fidelity and frequency response performance whilst still providing excellent resistance against moisture, oil, heat and chemicals. Furthermore they’re tested against fog, salt and blazing sunlight so you can be sure they’ll sound great for many seasons to come.

For added convenience, included is a marine grade connection loom for a more robust installation.
