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. These designs deliver massive amounts of highly-accurate bass and can be driven with punishing levels of amplifi er power.

The CompVT high performance suspension system 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

flat 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 produces 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 the airspace

Use 1/2” (1.3cm) or thicker MDF (medium density

fiberboard) and seal the joints with silicone. Use the “template” inside your CompVT’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 6. All the cubic feet (L) measurements in this manual include the displacement of the woofer. If you prefer an ultra- smooth bass response, you should loosely fi ll your CompVT enclosure with poly-fi l stuffi ng. The use of poly-fi l will slightly decrease effi ciency, but will deepen and extend the low frequency output.

CompVT 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.

CLEARANCE PLATE INSTALLATION

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.

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.
