Alpine S-Series S-S57 5x7-inch Coaxial 2-Way Speakers

The Alpine S-Series S-S57 5x7-inch coaxial 2-way speakers are engineered to deliver impressive sound quality as an ideal upgrade for factory audio systems. These speakers feature a lightweight yet rigid Carbon Fiber Reinforced Plastic (CFRP) woofer cone, a material exclusive to Alpine's S-Series, which is manipulated during the molding process to strengthen naturally weaker areas of the cone. This results in enhanced rigidity throughout the cone, providing accurate and efficient performance with reduced distortion.

The S-S57 speakers incorporate Alpine's patented H.A.M.R. (High Amplitude Multi-Roll) rubber surround. This proven technology increases the speaker's excursion while maintaining accuracy and linearity, allowing for significant linear air movement and contributing to a cleaner, more precise sound. High frequencies are handled by a 1-inch silk dome tweeter, designed to produce a smooth, wide frequency response without causing listening fatigue.

With a power handling of 75 watts RMS (230 watts peak), these speakers offer a significant boost in clarity and detail over stock speakers. They are designed for easy installation in most vehicles that accommodate 5x7-inch or 6x8-inch speaker openings, making them a versatile choice for a wide range of car audio upgrades.
