Rockford fosgate hx2 subwoofer with box

The engineers at Rockford Fosgate actually are alchemists who have found a way to transform base materials into low frequency gold. Raw materials like aluminum and paper have been conjured into the RFD2215 15" Punch HX2 subwoofer that hits deep, low, and clean. Aluminum voice coil formers dissipate heat and minimize distortion, while the cast aluminum frame basket increases the woofer's stability, controlling unwanted resonances. The unique FIBERlock cone of specially-bonded, industrial-strength paper is strong and lightweight for superior sound and durability. Add a durable Santoprene rubber surround to the brew and you have maximum cone excursion for maximum bass. The dual voice coil structure (two 3", 4-ohm coils) provides hook-up options from a 2- to 8-ohm load. Note: If you are wiring this DVC sub for lower impedance, make sure that your amp is compatible. Most car amplifiers are stable down to 2 ohms in standard mode, or 4 ohms in bridged operation.
