VENTED ENCLOSURE APPLICATIONS
The smaller enclosures are best for use in limited-space applications. The larger recommended
enclosures will yield slightly more bass at the lowest frequencies.
The vented minimum design increases bass effi ciency
and fi ts in many space-limited applications. Although
it is the smallest recommended vented enclosure, the
output from 30Hz–80Hz will be considerably higher than
that of a sealed box. The maximum vented design has
even more output in this frequency band. The maximum
vented enclosure is the largest and most effi cient design.
BOX BUILDING NOTES
Use 3/4” (1.9cm) or thicker MDF (medium density
fi berboard) and seal the joints with silicone. Use the
“template” inside your CompVT’s shipping carton to mark
the mounting hole, then cut directly on the line. These
designs need internal bracing. Add triangular bracing
between each of the larger unsupported panels. See
Figure 4.
