• 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.
• Al l encl osure vol umes l i sted are net i nternal vol umes!
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.
• When using two subwoofers in a common
enclosure simply doubl e the required volume and,
in the case of a ported enclosure,use two ti mes the
recommended port(s).
• We recommend the use of this speaker in a bi -
ampl i f i ed system using high-quality satellite speakers
and amplifiers. We do not recommend the use of
thissubwoofer with apassi ve crossover (coi l ), as thi s
type of device will adversely affect performance.
