Kicker L5 - Manual (Page 14)

All the cubic feet numbers given in the supplied charts include the displacement of the woofer. For the ported
boxes the displacement of the port must be added to the final design. It will be impractical to use round ports for
these designs. The rectangular port information given will yield the best results.
Always use 3/4” or thicker MDF and make sure all the joints are secure and well sealed. The peak pressure in a
ported box can exceed that of a sealed enclosure. All of these
designs need some internal bracing. Be sure to add 2”x2” to 3”x3”
triangle braces between each of the larger unsupported panels.
Kicker recommends using a good grade of wood glue and silicone
sealer for an airtight box.
Note:If you prefer an ultra-smooth bass response, you should
loosely fill your ported Solo-Baric Enclosure with polyfil. If you do
so, the entrance to the port (inside the box) must be covered with
hardware cloth, chicken wire, or expanded metal to prevent the
polyfil from being blown out through the port. Use of polyfil will
slightly decrease efficiency, but will deepen and extend low bass
response.
Do not install a ported box with the port against a solid
surface. The port opening must remain unobstructed.
Use the smallest dimension of the rectangular port as
the minimum amount of space required between the
port and any surface to insure unrestricted airflow.
