•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).

18W6 specifications

JL Audio is a name synonymous with high-quality audio performance, especially in the realm of subwoofers, and the JL Audio 18W6 is no exception.
