Wiring
Solo-Baric L7 woofers are available with dual 2 Ohm and dual 4 Ohm voice coils. Both coils should always be hooked up.
The dual 2 Ohm woofer will give you a 1 Ohm or a 4 Ohm load depending on if the coils are wired in parallel or in series. The dual 4 Ohm
woofer will give a 2 Ohm or 8 Ohm load depending on how they are wired.
The terminals with solid red and black markings are for one voice coil. The terminals with the white dots are for the second voice coil.

A Note on Power Handling Capability
Solo-Baric subwoofers will handle their full rated power in any of the recommended enclosures, minimum or maximum. The smaller enclo-
sures are best for use in limited space applications. The larger (maximum) recommended enclosures will yield slightly more bass at the lowest
frequencies.The power ratings given are assuming that both voice coils are used. You should never hook up a dual voice coil woofer using only
one coil.
Box-Building Notes
The cardboard support inside your Solo-Baric’s shipping carton can be used as a template for cutting the speaker mounting hole in the enclo-
sure you build. Since the cardboard cut-out is the same size as the basket of the L7, when you make the cut along the line drawn through the
template, make sure to cut right on the line to get the correct opening size.
All the cubic feet numbers given in the above 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, chick-
en 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 unobstruct-
ed. 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.
The following pages contain drawings and cut sheets for the ported enclosure designs recommended in
this paper.
