SEALED ENCLOSURE APPLICATIONS
The Solo Classic is designed to be used solely with smaller, sealed enclosures and will generate more
sound pressure than any competing subwoofer on the market. The outlined sealed enclosure designs
give the smoothest response with increased energy at the lowest frequencies, 20 to 30Hz. These designs
deliver large amounts of highly-accurate bass and can be driven with punishing levels of amplifi er power.
All the cubic feet (L) measurements in this manual include the displacement of the woofer. Do not make
the airspace greater than the recommended enclosure volume, as damage may occur. If you prefer an
ultra-smooth bass response, you should loosely fi ll your Solo Classic 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.
Use 3/4” (1.9cm) or thicker MDF (medium density fi berboard) and seal the joints
with silicone. Use the “template” inside your Solo Classic’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, making certain to account for the added volume displacement.
