VentedEnclosureApplications

Ported CompVXs? Absolutely...and with a vengeance! These enclosures incorporate massive slot- loaded (rectangular) ports with ultra low air velocity for ground pounding street bass that will make your “skin bounce on your bones!”

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.

The ported Compact design increases bass efficiency and fits 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.

INSTALLATION	The SPL / Deep Bass is the largest and most efficient enclosure design. The SPL / Deep Bass delivers
	the sonic output needed to win SPL contests and it produces bass notes “all the way down to the
	cella”. This design turns heads and jump starts your heart.
	Model:	VentedCompact (MinimumEnclosureVolume)	VentedSPL/DeepBass (MaximumEnclosureVolume)
	CVX10	1.25ft3 (35.4L) + port displacement	1.75 ft3 (49.6L) + port displacement
		2 x 10.5” (5.1x26.7cm) port, 20” (50.8cm) long	2.5 x 10.5” (6.4x26.7cm) port, 20” (50.8cm) long

If you prefer an ultra-smooth bass response, you should loosely fill your CompVX enclosure with poly-fil 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 exiting the port. The use of poly-fil will slightly decrease efficiency, but will deepen and extend the low frequency output.

BoxBuildingNotes

Use 3/4” (1.9cm) or thicker MDF (medium density fiberboard) 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 final 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.

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 airflow.

The displacement of the port must be calculated and added to the internal volume of the final design. The dimensions for X, Y, and Z may vary based on the thickness of the material used to make the port.

A Note on PowerHandlingCapacity

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 listed Power Handling capacities assume that both voice coils are in use.

Always connect both coils in a dual voice-coil speaker.

Note: The use of a subsonic filter will significantly increase the power handling.	5
The power handling specifications in these charts are calculated using a 25Hz, 24dB per octave subsonic filter.
