Alpine S2-S65 S-Series 6.5" Coaxial 2-Way Car Speakers

Looking to upgrade your ride's sound system without blowing your whole paycheck? The Alpine S2-S65 coaxial speakers might just be the sweet spot between killer sound and solid value. Designed to deliver crisp highs and deep lows, these 6.5" 2-way speakers bring high-res audio quality into the realm of everyday drivers like you and me.

Hi-Res Audio That Hits Every Note

These aren’t your average entry-level speakers. The Alpine S2-S65 speakers are Hi-Res Audio Certified, which means they can reproduce frequencies all the way up to 40kHz. If you're chasing that crystal-clear sound with richer detail and smoother tones, this upgrade makes a real difference—think of it as upgrading from standard definition to 4K, but for your ears.

A Cone Built for Clarity and Power

Alpine didn't mess around with the materials here. The woofer cone combines polypropylene, glass fiber, and mica—fancy words that basically mean it’s strong, light, and made for accuracy. Whether you’re cranking up the volume or catching the subtle details in a slow jam, the S2-S65 handles it all without distortion.

The Secret Sauce: HAMR Surround

One of the standout features is Alpine’s High-Amplitude Multi-Roll (HAMR) surround tech. What’s that in plain English? It allows the speaker cone to move more freely—giving you punchier bass and cleaner mids. It’s like giving your music room to breathe so every beat hits just right.

Built-In Tweeters for Balanced Sound

No need for separate components—these coaxial speakers include integrated 1” tweeters that sit right in the center. That means you’re getting a full-range sound from one convenient setup. Crisp vocals? Sharp cymbals? Covered and sounding smooth.

Sleek Grille Option for Protection

While not included, the Alpine S2-S65 is compatible with the optional KTE-S65G speaker grille. It adds a sleek finish and helps protect your gear from accidental damage or curious kicks from backseat passengers.
