Descrizione

he 12W1v2 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 12W1v2-4 is best used with amplifier power in the 75W – 300W range and is optimized to operate in a compact 1.25 cu. ft. (35.4 l) sealed enclosure, or a 1.75 cu. ft. (49.5 l) ported enclosure. Detailed enclosure recommendations can be found in the “Specifications” tab.
