Next-Generation S-Series 5-1/4″ 2-way car speakers

It’s time for high-res. We’re big fans of Alpine’s push to give more drivers access to high-res audio in the car. Using technology developed for their flagship F#1 Status Series, Alpine’s Next Generation S-Series car speakers provide access to all the wonderous detail of your favorite high-resolution audio files at an appealing price. We recommend aftermarket power to drive these speakers, but even with factory power, their ultra-wide frequency response ensures a detailed, authentic sound. Innovative materials. Alpine packs supreme capability into these speakers by using highly effective materials and proprietary design elements. The lightweight woofer cone, crafted from polypropylene, glass fiber, and mica materials, serves up the essential high output/low distortion sound required for high-res performance. The woofer’s High Amplitude Multi-Roll (HAMR) surround brings out the best in bass by allowing maximum cone movement. A 3/4″ cloth dome tweeter serves up all the high-frequency detail you’ve been missing with your factory speakers. Grilles are not included; the factory grilles should be suitable for most applications. Optional grilles are available for custom installations.
