Alpine S2-S40 - 2-way coaxial system

Alpine S2-S40 2-way coaxial speaker system

The newly designed and Hi-Res Audio certified S-Series S2-S65 10 cm coaxial speakers of the S-Series offer a new standard for premium sound performance in the entry-level segment.
By using highly effective materials and proprietary design elements, we have packed the highest level of performance into these speakers.
The lightweight woofer membrane, which consists of a combination of polypropylene, glass fiber and mica, delivers the sound required for High-Res Audio .
And all this with high power and low distortion.
/>The woofer's High-Amplitude Multi-Roll (H.A.M.R.) surround ensures optimal bass reproduction by allowing maximum movement of the diaphragm.
A 2 cm dome tweeter delivers all the high-frequency detail you've been missing from your factory speakers.
All S-Series speakers have a wide range of application for in-vehicle installation and are supplied with various adapters and spacers.
By using integrated crossovers, these speakers can also be installed quickly and easily yourself.
Alpine S-Series speakers are available in coaxial and component variants and are offered in a range of sizes, e.g. B. 20 cm, 16.5 cm, 13 cm, 10 cm, 6x9 inches and 6x8 inches.
