JL Audio 8W1v3-4 8" Subwoofer Driver 150 W 4 Ω
Need Help?
The 8W1v3 is an outstanding choice when space is very tight and amplifier power is moderate. It features shallow mounting depth (3.86 in. / 98 mm) and a compact motor structure, allowing it to comfortably fit in a lot of spaces where a typical 8-inch driver will not. Lacking a pole vent, 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 8W1v3-4 is best used with amplifier power in the 50W - 150W range and is optimized to operate in a compact 0.350 cu. ft. (9.90 l) sealed enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.
