VENTED
ENCLOSURE APPLICATIONS
CompVX
subwoofers will handle massive amounts of power
in
any of the recommended enclosures,
minimum or maximum. 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 ported
enclosure, the output from
30
to
80Hz
will be
considerably higher than that of any sealed box. The
Vented Maximum design has even more output
in
this
crucial frequency band. The Vented Maximum
is
the
largest and most efficient enclosure 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
CompVX'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
3.
All
the cubic feet
(L)
measurements
in
this manual
include the displacement of the woofer. For the vented
enclosures the displacement of the port must be
calculated and added to the internal volume of the
final
design.
Use the outer dimensions of the port and multiply
