Additional
AdditionalThe enclosure recommendations listed above are external dimensions which assume the use of 0.75" (19 mm) thick material. If you are using 0.625" (16 mm) thick material, subtract 0.25" (6.5 mm) from each dimension. Do not use any material with a thickness of less than 0.625" (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. When using multiples in a common enclosure you will need to recalculate the enclosure and port dimensions. For assistance please contact your authorized JL Audio dealer or JL Audio Technical Support. We recommend the use of this in a bi-amplified system using high-quality satellites and a high-quality amplifier. We do not recommend the use of this with a passive crossover (coil), as this type of device will adversely affect performance.
