With an output of 300W at 2 ohms, remarkable excursion and linearity as well as optimum performance and reliability thanks to JL Audio's unique technologies, this could be the missing piece of the puzzle in your sound experience. It is no coincidence that the 12W1V3-2 was rated 1.5 and "very good" in the 3/2014 issue of Car & Hifi magazine. Look forward to shockingly deep and high-quality sub-bass.
Features
- The 12W1v3 is a lightweight 12-inch driver with excellent performance characteristics at moderate power levels.

- Thanks to its excellent excursion and linearity, it can reproduce sub-bass with shock-like extension and quality.
- Several proprietary technologies from JL Audio enhance its performance and reliability.
- The 12W1v3-2 is best used with amplifier power levels in the 75W - 300W range and is optimized for operation in a compact, 31.5L (1.10 cu. ft.), sealed enclosure.
