Figure 2 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 vent and multiply
"Xx Y x Z" ,
and convert to cubic feet, for example the CWQ12 Vented Minimum
design's external vent dimensions are, using 3/4" (1.9cm) MDF:
[ (13.25"
+
1 :5" total MDF wall thickness) x (2.5"
+
1.5" total MDF wall thickness) x 22.5") x
(1 ft3 / 1728 in
3
)
= .77 ft3
Add this number to the internal volume of the enclosure. The CW012 is:
1.75 ft3 + .77 ft3 = 2.52 ft3 ,
Due to the necessary length of these vents, you may want to fold the vent along the bottom and back walls. It will
be impractical to use round vents for these designs. Do not install a vent opening against a solid surface, such
CWQ12, CWQ15: D = 3"
x
3"
CWQ10: D = 2"
x
2"
as an internal brace, back-panel or trunk wall, seat or interior panel of your vehicle. The vent opening must remain
unobstructed. Use the smallest dimension of the rectangular vent as the minimum amount of space between the vent
opening and any solid surface to insure unrestricted airflow.
If you prefer an ultra-smooth bass response, you should
loosely fill your Compo enclosure with poly-fil stuffing. Vented 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

WARNING: KICKER products are capable of producing sound levels that can permanently damage your hearing!
Turning up a system to a level that has audible distortion is more damaging to your ears than listening to an
undistorted system at the same volume level. The threshold of pain is always an indicator that the sound level is too
loud and may permanently damage your hearing. Please use common sense when controlling volume
IMPORTANT SAFETY WARNING - PROLONGED CONTINUOUS OPERATION OF AN AMPLIFIER
IN A DISTORTED OR CLIPPED MANNER CAN CAUSE YOUR AUDIO SYSTEM TO OVERHEAT,
POSSIBLY CATCHING FIRE AND RESULTING IN SERIOUS DAMAGE TO YOUR COMPONENTS
AND/OR VEHICLE.
