Box Building Notes

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.

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.
