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 efficiency
and fits
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 efficient design.
BOX
BUILDING
NOTES
Use 3/4"
(1
.9cm) or thicker MDF (medium density
fiberboard) 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.
