Kicker Solo-Baric L7-Series, Technical Manual

Page: 14 / 36

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.
