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 CompVX, try one of these ported designs. You will not be disappointed. CompVX 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 CompVX’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 4.

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 CVX12 vented compact design’s external port dimensions are, using 3/4” (1.9cm) MDF:

[ (2.5” + 1.5” total MDF wall thickness) x (12.5” + 1.5” total MDF wall thickness) x 20”] x (1 ft3 / 1728 in3) =

.65 ft3, and add this number to the internal volume of the enclosure, CVX12’s 1.75 ft3 + .65 ft3 = 2.40 ft3. See Figure 5. 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.

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.

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 CompVX 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.
