Alpine S2-S65 S-Series 6.5" (16.5cm) 2-Way Coaxial Car Speakers | 240W

The Alpine S2‑S65 6.5″ coaxial car speakers are engineered to raise the performance of your vehicle’s stock audio system. Designed as part of Alpine’s next‑generation S‑Series, these speakers use a lightweight woofer made from a combination of polypropylene, glass fiber, and mica, giving them excellent power handling and low distortion characteristics. Alpine’s High‑Amplitude Multi‑Roll (HAMR) surround allows maximum cone movement, resulting in improved bass performance and overall sound accuracy — even at higher volumes.

Certified for Hi‑Res Audio up to 40 kHz, the S2‑S65 reproduce a wide frequency range with clarity, making vocals, instruments and high‑frequency audio more natural and engaging. The integrated 2.5 cm (1″) dome tweeters provide crisp treble detail that complements the robust mid‑bass output. Whether used with the factory stereo or in tandem with an aftermarket head unit or amplifier, these speakers deliver balanced performance suitable for daily listening or music enthusiast setups.

Built for easy installation, the Alpine S2‑S65 fits many standard factory mounting locations and includes several spacers and adapters. For added protection and style, optional KTE‑S65G speaker grilles are compatible (sold separately). These speakers also match well with Alpine S‑Series amplifiers and subwoofers, allowing scalable audio upgrades that improve overall system cohesion.
