Alpine S2-S40C Two Way 4″ (10cm) 140watts 4Ω Component Speakers

The newly redesigned Alpine Next-Generation S-Series S2-S40C 10cm (4”) Component Speakers set a new benchmark for entry-level car audio performance. Now Hi-Res Audio Certified, these speakers deliver exceptional clarity, detail, and power, making them a perfect upgrade from factory systems. Inspired by Alpine’s flagship F#1Status technology, the S-Series brings premium sound quality within reach, reproducing frequencies up to 40kHz for a more natural and accurate listening experience.

Engineered with high-performance materials, the lightweight woofer cone combines polypropylene, glass fiber, and mica to achieve high output with low distortion. This advanced construction ensures clean, accurate midrange and improved mid-bass response, while the larger magnet design enhances power handling for richer, more dynamic sound across all volumes.

For powerful bass performance, Alpine’s exclusive High Amplitude Multi-Roll (HAMR) surround allows maximum cone movement, delivering deeper and more controlled low frequencies. High-frequency detail is handled by a 2cm (3/4”) dome tweeter, bringing out crisp highs and clarity that factory speakers simply can’t match.

Designed for versatility, the S2-S40C speakers offer a wide range of vehicle fitments and include multiple adapters and spacers for easy OEM integration. In-line crossovers simplify installation, making them suitable for both professional and DIY setups. The adjustable tweeters feature removable flush-mount housings, allowing seamless installation even in compact factory tweeter locations or custom builds.

Built to pair perfectly with Alpine S-Series amplifiers and subwoofers, these component speakers are ideal for customers looking to build a complete, great-sounding system without exceeding their budget. With Hi-Res Audio performance, powerful bass, and simplified installation, the Alpine S-Series S2-S40C delivers premium sound quality and outstanding value for any car audio upgrade.
