SONAFILL INSTALLATION INSTRUCTIONS
The Sonafill™ system is composed of four 6” x 12” damping tiles and
two square acoustic pillows. The four tiles are adhered to the inside
surface of the wall above and below the speaker cutout; the pillows are
placed in the wall cavity above and below the speaker cutout. The
Sonafill system greatly reduces the coloration caused by drywall reso-
nance. Another benefit of the Sonafill system is the reduction in sound
transmitted to the room located behind the speaker.
Step 1
Sonafill installation begins with the drywall installed and finished and
the speaker mounting hole already cut. Any fiberglass already in the
stud bay where your Sonafill will be installed should be pushed away
from the speaker cutout approximately 15” up and down. This allows
enough space for installation of Sonafill and its proper operation.
Step 2
Locate the four Sonafill adhesive-backed damping tiles. Lightly brush
off any debris from the inside surface of the drywall where the Sonafill
will be installed. Peel the protective coating off the back of one of the
tiles. Fit the tile through the speaker cutout with the adhesive side fac-
ing you. Attach the first tile 2” above the speaker cutout and to the left
of center. Install the second tile 2” above the speaker cutout and to the
right of center. Repeat the process for the remaining two tiles 2” below
the speaker cutout. The adhesive on the tiles is tenacious; be sure to
plan the installation of the four tiles before attaching.
Step 3
Locate the two acoustic pillows. Install one pillow inside the wall 2”
above the speaker cutout. Install the second pillow 2” below the speak-
er cutout. The pillows contain a randomly-twisted fiberglass. This
type of fiberglass is designed to eliminate sagging and movement after
installation, so the acoustic pillows will stay where they are needed.
Once installed, the acoustic pillows break up any standing waves that
occur in a wall cavity.
Step 4
Install the speakers in the wall as usual. You will notice a dramatic
increase in the clarity and definition of bass and mid bass frequencies.
The reduction of drywall resonance will be most noticeable on male
voice, drums, bass guitar, as well as any type of surround sound effect
containing low to mid frequencies.
