Ported Enclosure

•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).

•Do NOT use different impedance speakers when using multiple subwoofers!

•JL Audio recommends using subwoofers as part of a bi-amplifiedsystem 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-PortSystem. TheFlex-Porttubing 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.
