A Note on Power Handling Capacity
CompVR subwoofers will handle large amounts of power in any
of the recommended enclosures, sealed or vented. 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 listed Power Handling capacities
assume that both voice coils are in use. Always connect both
coils in a dual voice-coil speaker.
The cardboard “Template” inside your CompVR’s shipping
carton can be used as a pattern for cutting the speaker mounting
hole in your enclosure. The cardboard template is the same size
as the CompVR basket. After marking your baffle with the
template, make sure to cut directly on the line. This will maintain
the proper baffle cut-out size for the CompVR basket.
All the cubic feet numbers given in the following pages include
the displacement of the woofer. For the ported enclosures the
displacement of the port must be added to the final design. It will
be impractical to use round ports for these designs. The listed
rectangular port information will yield the best results.
Always use 3/4" (1.9 cm) or thicker MDF (Medium Density
Fiberboard) and make sure all the joints are fastened and well
sealed. The peak pressure in a ported box can exceed that of a
sealed enclosure. All of these designs need some internal
bracing. Add 2" x 2" (5 cm x 5 cm) to 3" x 3" (8 cm x 8 cm)
triangle braces between each of the larger unsupported panels.
Kicker recommends using a high-grade wood glue and silicone
sealer for an airtight box.

Note: If you prefer an ultra-smooth bass response, you should
loosely fill your CompVR enclosure with poly-fil (polyester fiberfill)
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 being blown out of the port. The
use of poly-fil stuffing will slightly decrease efficiency, but will
deepen and extend the low frequency output.
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 or the diameter of
the round port as the minimum amount of space between the
port opening and any solid surface to insure unrestricted airflow.
