Use
3/4"
(1
.9cm) or thicker MDF (medium density fiberboard) and
seal
the joints with
silicone. Use the
"template"
inside your
Solo
Baric'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 3.
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
L7S12
vented Minimum design's
external port dimensions
are,
using 3/4"
(1
.9cm) MDF: [ (13.25"
+
1

wall
thickness) x
(2.5"

(1

= .

,
and add this number to the
internal volume
of the
enclosure,
L7S12's 1 .75
ft

+
.77

=
2.52
ft3.
See
Figure 4.
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 oorts for these designs.
