NOTE: The enclosure recommendations listed are external dimensions which assume the use of 3/4" (19mm)
thick material. If you are using 5/8" (16mm) thick material, subtract 1/4" (6.5mm) from each dimension. Do not use
any material with a thickness of less than 5/8" (16mm) as this may compromise the rigidity of the enclosure.
NOTE: 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.
