Alpine S2-W12D2 12-Inch S-Series Subwoofer Product Overview: The S2-W12D2 is the redesigned, next-generation 12-inch S-Series subwoofer. Engineered to deliver Hi-Res Audio performance, this driver offers powerful and reliable bass at an approachable price point. Featuring Dual 2-Ohm Voice Coils, it provides maximum flexibility for wiring configurations, making it a versatile choice for a wide range of aftermarket sound systems. Features Enhanced Punch & Clarity The S2-W12D2 features a newly developed cone made from a carbon fiber and polypropylene blend. This combination ensures the driver is lightweight yet incredibly rigid, allowing for deep, high-impact bass with significantly lower distortion. The polypropylene and ceramic dust cap further reinforces the structure for consistent performance under heavy loads. High-Amplitude Multi-Roll (HAMR) Surround Borrowing technology from Alpine’s high-end R and X-Series, the S2-W12D2 utilizes the proprietary HAMR rubber surround. This design allows the cone to move air efficiently while staying cool and stable. It supports an impressive 15mm of one-way linear excursion, ensuring incredible accuracy and physical impact even at high volumes. Seamless Connectivity Installation is simplified with Push-Type speaker terminals that accommodate wire sizes up to 8AWG. The Dual Voice Coil (DVC) design includes easy-to-use configuration jumpers, allowing customers to quickly switch between different impedance loads to match their amplifier’s requirements without complex wiring. Flexible Application & Protection The subwoofer is designed for versatility, performing exceptionally well in both sealed and ported enclosures. It also features a new Twist-Lock grille mounting system, which allows customers to easily install or remove an optional protective grille (sold separately) without the need for mounting screws, maintaining a clean and professional look.
