Give Your Factory Sound the Upgrade It Deserves

Upgrade your factory audio system with the Alpine S2-S40 4-inch coaxial speakers. Designed for listeners who want cleaner highs, clearer vocals, and more detailed sound without taking up extra space, these Hi-Res Audio Certified speakers bring trusted Alpine performance to your daily drive.

Enjoy Detailed Hi-Res Audio Performance

Hi-Res Audio certification and a frequency response of 100Hz to 40kHz help the S2-S40 reproduce detailed sound across a wide range of frequencies. Enjoy crisp highs, clear vocals, and a more engaging listening experience with your favorite music.

Durable Cone Construction for Clear, Responsive Sound

The polypropylene cone features glass fiber and mica reinforcement, creating a strong yet lightweight design. This construction supports controlled cone movement and helps deliver clear, balanced, and responsive audio performance.

Smooth High Frequencies with a Built-In Tweeter

The integrated 3/4-inch cloth-dome tweeter helps reproduce smooth and detailed high frequencies. Its coaxial design combines the woofer and tweeter in one compact speaker, making it a practical upgrade for compatible factory speaker locations.

H.A.M.R. Surround Technology for Enhanced Bass

Alpine's High-Amplitude Multi-Roll (H.A.M.R.) surround technology allows increased cone movement for stronger, more controlled bass. This design helps the compact S2-S40 deliver a fuller sound while maintaining clear audio reproduction.

Reliable Power Handling for Everyday Listening

With 45 watts RMS and 140 watts peak power handling per speaker, the Alpine S2-S40 is built to deliver consistent performance for everyday listening. Its 4-ohm design makes it suitable for compatible aftermarket head units and properly matched amplifiers.

Compact 4-Inch Design for an Easy Audio Upgrade
