Enclosure Construction
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.
