Enclosure Recommendations
www.PrecisionPower.com
Included in this manual are a number of different enclosure suggestions. 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 Pre-
cisionPower dealer.
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.
