Congratulations on your new Soundstream sub-woofer purchase. We
greatly appreciate your business. This may look like is a run of the mill
cardboard box, but is actually a protective barrier over one of the finest
engineered and assembled subwoofer available.

Soundstream does not provide enclosure dimensions as there are
infinite variables when designing a box, i.e. vehicle, amplifier, music
preferences, etc… For designs tailored to your specific needs, please
contact us at tech-support@soundstream.com
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 wil
l improve response by smoothing out reflections within the
enclosure
