Box Building Notes
Use 3/4" (1.9cm) or thicker MDF (medium
density fiberboard) and seal the joints with
silicone. Use the "template" inside your
GOLD 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 the
larger unsupported panels.
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 GOLD12 Vented
Minimum design's external port dimensions
are, using 3/4" (1.9cm) MDF:
(12.5" + 1.5" total MDF wall thickness) x
(2.5" + 1.5" total MDF wall thickness) x
(20") x (1 ft
/ 1728 in
) = .65 ft

Then, add this number to the internal
volume of the enclosure. 1.75 ft
+ .65 ft
=

2.4 ft

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.
