Newly redesigned and Hi-Res Audio Certified, the Next-Generation S-Series S2-S40 10cm (4”) Coaxial Speakers offer a new standard in entry-level sound performance. We packed supreme capability into these speakers by using highly effective materials and proprietary design elements. The lightweight woofer cone, crafted from a combination of polypropylene, glass fiber, and mica materials, serves up the essential high output / low distortion sound required for High-Res Audio performance. Alpine S-Series speakers feature increased magnet sizes for more power handling and best mid-bass performance in their category. The woofer's High Amplitude Multi-Roll (HAMR) surround brings out the best in bass by allowing maximum cone movement. A 2cm (3/4") dome tweeter serves up all the high-frequency detail you've been missing with your factory speakers.
