JL Audio W0-Series 15-Inch 500-Watt Subwoofer Driver, 4-Ohm SVC
The JL Audio 15" W0v3 automotive subwoofer driver offers excellent excursion capability and linearity in a 500W price point. This 15-Inch sub features a very beefy 2.5 in. diameter voice coil and JL's patented Elevated Frame Cooling design for enhanced power handling and reliability.
The 15W0v3-4 is best used with an amplifier in the 150-Watt - 500-Watt range and is optimized to operate in a moderately sized 1.875 cu. ft. (53.1 l) sealed enclosure, or a 2.75 cu. ft. (77.88 l) ported enclosure.
