Alpine S2-S40

Newly designed and Hi-Res Audio certified, the next generation of S-Series S2-S40 10 cm (4”) coaxial speakers offer a new standard in entry-level audio performance.

We've packed these speakers with exceptional capability by using high-performance materials and proprietary design elements. The lightweight woofer, made from a combination of polypropylene, fiberglass and mica materials, delivers the necessary high-end sound with low distortion required for Hi-Res Audio performance. Alpine S-Series speakers feature larger magnets for higher output and best-in-class mid-bass performance.

The bass's High Amplitude Multi-Roll (HAMR) surround brings out the best in the bass by allowing maximum diaphragm movement. A 2 cm (3/4") dome tweeter provides all the high-frequency detail you've been missing from your factory-installed speakers.

All speakers in the S-Series line have a wide vehicle fitment range and include multiple adapters and spacers. With the help of in-line crossovers, these speakers can be installed quickly and easily even at home.

Alpine S-Series speakers are available in coaxial and component configurations and come in a variety of sizes, such as 20 cm, 16.5 cm, 13 cm, 10 cm, 6x9 inches and 6x8 inches.
