JL Audio 12W1v3 : 12-Inch 300-Watt Subwoofer Driver, 2-Ohm or 4-Ohm SVC
The 12" W1v3 automotive subwoofer driver by JL Audio is a lightweight 12-inch driver with excellent performance capabilities at a moderate 300-Watts. The design of the chassis allows an average mounting depth with no pole-vent on the back side of the magnet so the rear of the motor structure can be placed directly against an enclosure boundary. This 12" subwoofer can reproduce sub-bass with shocking extension and quality.
The JL Audio 12W1v3-2 and 12W1v3-4 subwoofers are best used with an amplifier in the 75W - 300W range and is optimized to operate in a compact 1.10 cu. ft. (31.5 l) sealed enclosure.
