JL Audio 13W3v3-4 13.5" inch Subwoofer, 4 Ohm, Single Voice Coil, 600 Watts 92157

If you have the space, it makes a tremendous sense to maximize your subwoofer system's piston area to enhance efficiency (and output). It gets even better when the larger driver delivers additional power handling and excursion. For the preceding reasons, the 13W3v3 can be the best choice for those seeking high output with great sound quality at medium power levels.

As with the smaller W3v3's, several exclusive JL Audio technologies and proprietary assembly techniques are applied to the 13W3v3 to enhance linearity and reliability.

The 13W3v3-4 is best used with amplifier power in the 150W - 600W range and is optimized to operate in a moderate size 1.75 cu. ft. (49.6 l) sealed enclosure, or a 2.5 cu. ft. (70.8 l) ported 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”.

Enclosure Notes * The enclosure recommendations listed above are external dimensions which assume the use of 0.75 in (19 mm) thick material. If you are using 0.625 in (16 mm) thick material, subtract 0.25 in (6.5 mm) from each dimension. Do not use any material with a thickness of less than 0.625 in (16 mm) as this may compromise the rigidity of the enclosure. * All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into account.
