Description

JL AUDIO 12W1V3-4 12″ SUBWOOFER (300 W, 4 Ω)

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 proprietary technologies enhance its performance and reliability.
