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 KM10 vented minimum design's
external port dimensions are, using 3/4" (1.9cm)
Marine Grade Plywood:
[ (1.5" + 1.5" total wall thickness) x (10.5" + 1.5" total
MDF wall thickness) x 14.5"] x (1 ft

More Box Building Notes: Use 3/4" (1.9cm) or thicker
Marine Grade Plywood and seal the joints with silicone. Use the
"template" inside your KM subwoofer'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
D
the larger unsupported panels.
All of the cubic feet (L) measurements in this manual include the
displacement of the woofer.
