JL Audio 6W3v3-4 W3v3 Series 6.5-inch Subwoofer, 4 Ω

* 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 are external dimensions which assume the use of 1/2 in (13 mm) thick material. Do not use any material with a thickness of less than 1/2 in (13 mm) as this may compromise the rigidity of the enclosure.
* All enclosure volumes listed are net internal volumes! Box volume displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions listed have already taken this into account.
* When using two subwoofers in a common enclosure simply double the required volume and, in the case of a ported enclosure, use two times the recommended port(s).

* When using multiple subwoofers in a common enclosure you will need to recalculate the enclosure and port dimensions.
