Included in this manual are a number of different enclosure sugges-
tions. These are by no means the only enclosures to use, but they
provide a starting point to determine the correct enclosure for your
needs many factors must be addressed (amount of power, vehicle,
placement, crossovers, etc) Therefore, as always PrecisionPower
recommends that your subwoofer be installed by an authorized
PrecisionPower
dealer.
Enclosure Dimensions
All enclosures should be made of .75” (3/4”) material only. When
possible, make the baffle 1.5” (1 ½) thick and add .75” (3/4”) to the
depth of the enclosure to compensate. All volumes INCLUDE vent/
port and subwoofer displacements. DO NOT change the volume
unless you plan on adding a substantial amount of bracing. For
added performance, applying a coat of fiberglass resin to the interior
walls will greatly improve sealing the enclosure. Adding a thin layer
of poly-fill will improve response by smoothing out reflections
within the enclosure.
