Alpine R2-W8D2 8-Inch R-Series Subwoofer Product overview: The Alpine R2-W8D2 is a next-generation 8-inch subwoofer from the legendary R-Series line, engineered to deliver massive bass in a compact footprint. This 2nd-gen model features a larger motor structure and double-stacked magnets for authoritative low-end performance. It’s the ideal choice for those who need high-output bass but have limited space, such as behind truck seats or in compact sealed enclosures. Features Seamless Connectivity The R2-W8D2 is built with Dual 2-Ohm Voice Coils, providing maximum wiring flexibility to match your amplifier’s optimal impedance. It includes easy-to-use configuration jumpers that allow you to quickly switch between a 1-ohm or 4-ohm load. For wiring convenience, the spring terminals are all located on one side of the woofer and can accept bare wire up to 8AWG or banana plugs. Safety & Convenience To protect your investment, the subwoofer features an "EZ-Change" twist-lock grille mounting system. This allows you to easily install or remove the optional KTE-8G protective grille (sold separately) without needing extra mounting screws. The rugged construction and Kevlar-treated pulp cone ensure the woofer remains durable and reliable even during extended, high-volume listening sessions in the harsh automotive environment. Enhanced Audio & Ambiance This subwoofer is Hi-Res Audio Certified, ensuring your bass isn't just loud, but incredibly accurate. It utilizes a polypropylene/ceramic composite dust cap that provides internal damping to smooth out frequency response and reduce distortion. The visual ambiance of your custom build is further enhanced by the clean, matte-black finish and the included cosmetic trim ring that hides the mounting hardware for a professional, stealthy look. Fine Tune Your Sound Alpine’s patented High-Amplitude Multi-Roll (HAMR) Surround allows for a massive 12mm of linear excursion, enabling the small 8-inch cone to move a tremendous volume of air. This results in the "thump" usually reserved for much larger drivers. You can "fine-tune" the performance by choosing your enclosure: it performs exceptionally in a tiny 0.3 cu. ft. sealed box for tight, accurate kicks, or a 0.73 cu. ft. ported box for maximum SPL output.
