Alpine S2-S50 | S-Series 5.25" Coaxial 2-Way Speaker Set The Alpine S2-S50 (MFR #: S2-S50) is a newly redesigned, Hi-Res Audio Certified coaxial speaker set that sets a new standar d for entry-level car audio performance. Drawing inspiration and "trickle-down" technology from the ultra-high-end AlpineF#1Status system, these speakers deliver an incredibly accurate and natural sound. With a compact 2-inch mounting depth, they are engineered for versatile installation in a wide variety of factory speaker locations. Product Highlights Hi-Res Audio Certified: Unlike standard car speakers, the Alpine S2-S50 is certified to reproduce frequencies up to 40 kHz. This extended range ensures that high-resolution audio files are delivered with all the detail and texture intended by the artist, providing a level of clarity rarely found in this price category. Advanced Material Construction: The woofer cone is crafted from a unique blend of polypropylene, glass fiber, and mica. This specific combination creates a lightweight yet rigid diaphragm that can move quickly with minimal distortion, resulting in a clean and highly responsive audio experience. HAMR Surround Technology: These speakers feature Alpine-exclusive High-Amplitude Multi-Roll (HAMR) surround technology. This specialized rubber surround allows for maximum, linear cone excursion, which enables the 5.25-inch woofers to deliver surprisingly powerful and accurate bass notes for their size. Integrated Silk Dome Tweeters: High frequencies are handled by integrated 3/4-inch silk dome tweeters. These drivers provide a smooth, non-fatiguing high-end response that perfectly complements the punchy mids of the woofer, ensuring a balanced soundstage throughout your vehicle. Key Features Trickle-Down Engineering: By utilizing performance cues from Alpine's flagship systems, the S-Series offers premium sound quality and engineering usually reserved for much more expensive components. Lightweight Design: The optimized motor structure and advanced cone materials ensure high output even when driven by factory head units, though they truly excel when paired with a dedicated aftermarket amplifier. Versatile Fitment: With a shallow 2-inch top-mount depth and standard 4.5-inch cutout diameter, these speakers are designed to be a direct "drop-in" upgrade for many vehicles, minimizing the need for custom fabrication. Optional Protection: For custom installations where the speakers are exposed, the S2-S50 is fully compatible with Alpine’s KTE-S50G mesh grilles (sold separately), which offer a sleek visual upgrade and protection from damage.
