fi nal design. Use the outer dimensions of the port and
multiply “X x Y x Z”, convert to cubic feet, for example
the Comp12 vented compact design’s external port
dimensions are, using 3/4” (1.9cm) MDF: [ (12.5” +
1.5” total MDF wall thickness) x (2.5” + 1.5” total MDF
wall thickness) x 20”] x (1 ft3 / 1728 in3 ) = .65 ft3, and
add this number to the internal volume of the enclosure,
Comp12’s 1.75 ft3 + .65 ft3 = 2.4 ft3. See Figure 4.
Due to the necessary length of these ports, you may
want to fold the port along the bottom and back walls. It
will be impractical to use round ports for these designs.
Do not install a port opening against a solid surface,
such as an internal brace, back-panel or trunk wall, seat
or interior panel of your vehicle. The port opening must
remain unobstructed. Use the smallest
dimension of the rectangular port as the
minimum amount of space between the
port opening and any solid surface to
insure unrestricted airfl ow.
If you prefer an ultra-smooth bass
response, you should loosely fi ll your
Comp enclosure with poly-fi l stuffi ng.
Ported designs will require covering the
end of the port (located inside the box)
with grill cloth, chicken wire, or expanded
metal to prevent the poly-fi l from exiting
the port. The use of poly-fi l will slightly
decrease effi ciency, but will deepen and
extend the low frequency output.

Sound Check: Poor bass response? Check the system phasing by reversing the positive and negative
speaker connections on the subwoofer. If the bass improves, then the subwoofer was out of phase in
reference to the rest of the audio system.
