JL AUDIO 12W1v3-4

JL AUDIO

(12W1V3-4) 12-INCH SUBWOOFER DRIVER (300W, 4 OHM)

OVERVIEW:

• The 12W1v3 is a lightweight 12-inch driver with excellent performance capabilities at moderate power levels. It features moderate mounting depth with no pole-vent, so the rear of the motor structure can be placed directly against an enclosure boundary. Excellent excursion capability and linearity allow it to reproduce sub-bass with shocking extension and quality. Several of JL Audio's proprietary technologies enhance its performance and reliability.
• The 12W1v3-4 is best used with amplifier power in the 75W - 300W range and is optimized to operate in a compact 1.10 cu. ft. (31.5 l) sealed enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.
