Pass speaker wire through hole in enclosure.
Seal wire hole with silicone.
Remove springs from installation blocks.
Attach enclosure to studs using at least four drywall screws per stud (two rows of holes are provided
for studs 16” and 24” on centers). Use fiberglass insulation between the back of the enclosure and
the interior drywall panel to minimize vibrations.
If studs are 16” apart, bend back the extended sides of the metal baffle; this is important to prevent
them from rattling.
Fill-up the enclosure with paper to prevent dust from contaminating the acoustical foam.
Install drywall in front of enclosure. If drywall is thicker than 5/8” please request our extension kit.
Use additional screws to secure the drywall to studs (these screws will pass through the multiple
perforations in the metal baffle). At least four screws per side are necessary.
Secure the drywall to the top and bottom sections of the enclosure with additional self-drilling screws
(already sent to you). Use three screws for the top and three screws for the bottom of the enclosure
this step.
Use a Roto-zip to cut speaker opening. Adjust the bit depth so the installation blocks are not
damaged.
Remove paper from inside the box, place the installation springs in MDF blocks, and install the
speaker following the instructions in the template.
Test thoroughly before mudding.
