Alpine S-Series S2-S40 - 4” 10cm 140 Watt 2 Way Coaxial Dash Door Speakers

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.

All speakers in the S-Series line have a wide vehicle fitment range and include several adapters and spacers. Using in-line crossovers, these speakers can be installed quick and easy even at home.

Alpine S-Series speakers are available in coaxial and component configurations and come in a variety of different sizes, such as 20cm, 16,5cm, 13cm, 10cm, 6x9 inches and 6x8 inches.
