HOLE DIMENSIONS
The subwoofer cabinet is approximately 16” in diameter and 32” long with the port tube attached.
Dig a hole that is at least 24” wide and 40” long so that it is about 4 inches larger than the sub in
each direction to allow for the sub to be adjusted side to side. Dig down 19” to 22” to allow for
adjustment of the port tube height.
The port tube height is adjustable by rotating the subwoofer in the hole. Provide at least 3” of soil
on top of the subwoofer cabinet, and at least 5” between the bottom of the canopy and the soil
surface after installation. This will allow for the best sound and will help prevent water buildup in
the enclosure.

ASSEMBLY AND SETUP
1. Insert the Canopy into one end of the port elbow until it is fully seated. Tighten the compression
clamp completely.
2. Assemble the subwoofer by fitting the open end of the port elbow onto the opening of the
subwoofer. Make sure the subwoofer port opening and elbow are free of soil so that a proper seal
can be made with the compression clamp. The elbow must be fully seated over the subwoofer
port opening. Do not tighten the compression clamp yet.
3. The height of the canopy can now be adjusted by rotating the subwoofer cabinet within the
hole. When the canopy is at the desired height, tighten the compression clamp completely to
attach the port elbow to the subwoofer cabinet.
4. Using the included silicone-filled wire nuts, complete the wiring connections. Match the
subwoofer’s Red lead to the “+” input and the subwoofer’s Black lead to the “-“ input of your
wiring.
5. Before filling in the hole for the subwoofer or any wiring trenches, test the complete speaker
installation, including the subwoofer and any other speakers.
Fill the remainder of the subwoofer hole with the soil removed earlier. Pack as much soil
around the sides and top of the subwoofer as possible. Make sure the port tube remains fully
perpendicular to the surrounding soil during this process. After the subwoofer is fully covered,
there should be at least 3 inches of soil covering the main assembly.
