Newly redesigned and HI-Res audio certified , the next-generation S2-S65 6-1/2″ coaxial speakers    deliver a new standard in entry-level sound performance.
We built supreme capability into these speakers through the use of highly effective materials and patented design elements. The lightweight woofer cone, made from a combination of polypropylene, fiberglass and mica materials, delivers the essential high-output , low-distortion sound required for Hi-Res audio performance. Alpine S Series speakers feature larger magnets for greater power handling and best- in-class mid-bass performance .
The woofer’s High Amplitude Multi-Roll (HAMR) suspension brings out the best in the bass by allowing maximum cone movement. A 2.5cm (1″) dome tweeter delivers all the high-frequency detail you’ve been missing with original speakers.
All speakers in the S Series line have a wide range of vehicle accessories and include various adapters and spacers. Using built-in filters, 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 different sizes, including 20 cm, 16.5 cm, 13 cm, 10 cm, 6 x 9 inches, and 6 x 8 inches.
