VENTED ENCLOSURE APPLICATIONS
These boxes are the enclosure of choice for outrageous street bass and high performance SPL contests.
If space is not a problem and you want to get the most from your CompVR, try one of these ported
designs. You will not be disappointed. CompVR subwoofers will handle massive amounts of power in
any of the recommended enclosures, minimum or maximum. 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 ported Compact design increases bass effi ciency and fi ts in many space-limited applications.
Although it is the smallest recommended ported enclosure, the output from 30 to 80 Hz will be
considerably higher than that of any sealed box. The SPL / Deep Bass ported design has even more
output in this crucial frequency band. The SPL / Deep Bass is the largest and most effi cient enclosure
design.
BOX BUILDING NOTES
Use 3/4" (1.9cm) or thicker MDF (medium density fi berboard) and seal the joints with silicone. Use the
"template" inside your CompVR's shipping carton to mark the mounting hole, then cut directly on the line.
These designs need internal bracing. Add triangular bracing between each of the larger unsupported
panels. See Figure 3.
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 fi nal
design. Use the outer dimensions of the port and multiply "X x Y x Z", convert to cubic feet, for example
the CompVR12 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 ft
and add this number to the internal volume of the enclosure, CompVR12's 1.75 ft
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 CompVR 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.
