The 10W1v3 is an outstanding choice when space is very tight and amplifier power is moderate. It features shallow mounting depth (4.6 in. / 117 mm) and a compact motor structure, allowing it to comfortably fit in a lot of spaces where a typical 10-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 10W1v3-2 is best used with amplifier power in the 75W - 300W range and is optimized to operate in a compact 0.55 cu. ft. (15.57 l) sealed enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.

* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
** Efficiency (1 W / 1 m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”.
