The Kicker CompVT subwoofers were specially designed for “Livin’ Loud” out in the harsh automotive environment. CompVT subwoofers are versatile and surpass the competition in a sealed or vented box. The ultra-thin mounting depth makes the CompVT subwoofers ideal for custom installations and space- limited applications. They are made using advanced materials and construction techniques to maintain optimal performance for years to come.

SEALED ENCLOSURE APPLICATIONS

The CompVT generates more sound pressure than competing subwoofers on the market and excels when used in the recommended sealed boxes. These sealed enclosure designs give the smoothest response with increased energy at the lowest frequencies, 20 to 40Hz. These designs deliver massive amounts of highly-accurate bass and can be driven with punishing levels of amplifi er power.

Sealed Compact				Sealed SQ
Model	Volume ft3 (L)		Power Handling		Model	Volume ft3 (L)		Power Handling
CompVT8	.4 ft3	(11.3L)	200W RMS		CompVT8	1.8 ft3	(51L)	200W RMS
CompVT10	.8 ft3	(22.7L)	400W RMS		CompVT10	3 ft3 (85L)		300W RMS
CompVT12	1 ft3 (28.3L)		400W RMS		CompVT12	4.6 ft3	(130L)	300W RMS

The CompVT high performance suspension

Bsystem can operate in a larger sealed enclosure. This maximum enclosure volume application is ideal for SQ (ultra sound quality) installations. The SQ enclosure generates

a very fl at response curve and superbly extends the subbass response. CompVT subwoofers perform well in any size sealed enclosure between the Compact and SQ volume recommendations. These systems will exhibit benefi ts of both designs: Compact

Cproduces high-impact bass, and SQ generates low bass frequency protraction. Overall, the system will sound more like the recommended enclosure design it is closest to in enclosure volume. These enclosure

recommendations have been calculated with

Athe airspace inside the enclosure and include the displacement of the woofer. All sealed enclosure airspace should be fi lled to 50% loose poly-fi l (polyester fi berfi ll) stuffi ng. Do

not make the airspace greater than the SQ maximum enclosure volume, recommendation.

To make the most effi cient use of space when building the compact sealed enclosure for your CompVT subwoofer, you must use the included clearance plate. The clearance plate allows the CompVT subwoofer to sit recessed within the back panel of the subwoofer box to minimize the enclosure’s depth. The clearance plate must seal tightly. First, use a plunging router, straight-cut bit, and a circle jig to create a 1/16” (2mm) deep recess with an outer diameter of 6 1/2” (16.7cm) and an inner diameter of approximately 5” (12.7cm). Center the recess behind the subwoofer on the back panel. Then, cut

a 5 1/4” (13.3cm) diameter hole in the center of the recess all the way through the back panel. Using the clearance plate as a reference, drill the six screw holes with a #29 (0.136”, 3.5mm) drill bit. Next, countersink each screw hole using a 1/4” (6mm) drill or countersinking bit so the clearance plate will

fi t tightly against the back panel. Remove the paper backing from the foam gasket and adhere it to the inside of the clearance plate. Then, fasten the clearance plate to the box with six #8 screws.
