•Enclosure dimensions listed are external dimensions which assume the use of 0.75 inch (19mm) thick material. If you are using
0.625 inch (16mm) thick material, subtract 0.25 inches (6.5mm) from each dimension. Do not use material with a thickness of
less than 0.625 inches (16mm).
•Enclosure volumes listed are NET internal volumes. Driver displacement, port displacement and brace displacement must be
added to obtain the final gross volume. The dimensions listed have already taken this into account.
•When using two subwoofers in a common enclosure simply double the required volumes and use two of the recommended ports
(when needed). Likewise, when using three subwoofers in a common enclosure simply triple the required volume and number
of ports (when needed).
*Efficiency (1W/1m) 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”!

•Do NOT use different impedance speakers when using multiple subwoofers!
•JL Audio recommends using subwoofers as part of a bi-amplified system using high quality satellite speakers like our Evolution line
of coaxial and component speakers. We do not recommend the use of passive crossover components (coils) on subwoofers. These
components may adversely affect the performance of a subwoofer.
•When dealing with exceedingly long port lengths, we recommend the use of JL Audio’s Flex-Port System. The Flex-Port tubing is
flexible, allowing it to fit in otherwise tight locations. The Port mouths provide not only a convenient method of securing the port,
but a smooth, rounded edge for the port termination as well.
With coils wired in parallel, a dual 6Ωspeaker will present a 3Ωload. With coils wired in series, a dual 6Ωspeaker will present a 12Ωload.
With coils AND speakers wired in parallel:
2 dual 6Ωspeakers (D6) will present a 1.5Ωload.
With the coils wired in series and the speakers wired in parallel:
2 dual 6Ωspeakers (D6) will present a 6Ωload.
With coils AND speakers wired in parallel:
3 dual 6Ωspeakers (D6) will present a 1Ωload.
With the coils wired in series and the speakers wired in parallel:
3 dual 6Ωspeakers (D6) will present a 4Ωload.
