Alpine S2-S40

The redesigned and Hi-Res Audio certified next-generation S-Series S2-S40 4-inch coaxial speakers set a new standard for entry-level audio performance.

We've packed these speakers with superior capability by using high-efficiency materials and proprietary design elements. The lightweight woofer cone, made from a combination of polypropylene, glass fiber, and mica materials, delivers the essential high power output/low distortion sound required for High-Res Audio performance. Alpine S-Series speakers have increased magnet sizes for more power handling and the best mid-bass performance in their category.

The woofer features a High Amplitude Multi-Roll (HAMR) surround that brings out the best in bass by allowing maximum cone movement. A 3/4-inch dome tweeter provides all the high-frequency detail you've been missing with your factory speakers.

All speakers in the S-Series lineup have a wide vehicle fit and include multiple adapters and spacers. By using in-line crossovers, these speakers can be installed quickly and easily even at home.
