Owner's Manual

final design. Use the outer dimensions of the port and
multiply "X x Y x Z", convert to cubic feet, for example
the Comp 1 2 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 I 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

= 3" x 3" for C15, C12
dimension of the rectangular port
as the
minimum amount of space between the
port opening and any solid surface to
Figure 4
insure unrestricted airflow.
If you prefer an ultra-smooth bass
response, you should loosely
fill your
Comp enclosure with poly-fil stuffing.
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-fil from exiting
the port. The use of poly-fil will slightly
decrease efficiency, 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.
