The Jensen J12W is a 12-inch car subwoofer rated at 300 watts RMS and 1,200 watts peak at 4 ohms. It uses a polypropylene cone, a reinforced stamped steel basket and a 40 oz magnet, and Jensen says it works in both sealed and ported boxes. It is a budget-minded driver for shoppers who want more low-end from a factory or entry-level system. Against pricier 12s it gives up excursion and power handling, and owners report it needs a properly sized enclosure and clean power to sound its best.
