MOUNTING OPTIONS (SAFETY FIRST)
When installing Atrium loudspeakers note
the weight of your particular model and the
weight bearing tolerance of the material to
which you’re mounting the speaker. If you’re
not sure of a safe way of mounting your
speakers, please consult a professional
installer, your authorized Polk Audio dealer
or a building contractor.
You’ll maximize the useful life of your Atrium
loudspeakers by placing them where they’ll
receive less exposure to the elements. If
extreme weather conditions are expected,
we recommend storing your speakers indoors.
Look for the best overall compromise between
sound quality, convenience and exposure.
Never compromise safety.
The Atrium’s Speed-Lock
mounting bracket
enables you to mount the speaker either horizon-
tally or vertically. The Speed-Lock bracket holds
the speaker in place so you can easily aim the
speaker to deliver the best possible sound in
a variety of situations. Follow the steps below
to safely secure the brackets and speakers.
Installing Atrium Series loudspeakers requires
basic skills in using tools such as a drill and
screwdriver. If you are in doubt that you possess
the necessary skills or tools, consult your
Polk Audio dealer, or a professional installer.
Horizontal & Vertical Mounting
1. Verify the material on which you plan
to mount the speakers (plaster, drywall,
paneling, stone, etc.) can support the
weight of the speakers:
Speaker Weights
Atrium4 3.6lbs / 1.63kg each
Atrium5 4.6lbs / 2.09kg each
Atrium6 5.4lbs / 2.45kg each
Atrium7 8lbs / 3.63kg each
Atrium8SDI 9.7lbs / 4.4kg each
2. Ensure the locations you select do not
conceal electrical wiring or plumbing.
3. Before you install the speaker, hold it in
the chosen location to make sure it safely
clears obstacles such as ceiling, adjacent
walls, corners, beams, lighting fixtures
and door/window frames.
4. Using the keyhole slots in the bracket as
a template, mark the installation location
of the two keyhole slots with a pencil. You
can do this by removing the bracket knobs
on the top and bottom of the speaker and
removing the bracket [figure 10].
5. Position the bracket so that the small ends
of the keyhole slots are facing “up” according
to the direction of installation.

PAINTING THE CABINET,
BRACKET KNOBS & BRACKET
1. Apply two thin coats of primer to the cabinet
and knobs. The bracket does not require
a primer.
2. Only after the primer is completely dry should
you apply the finish color [figure 8].
3. Do not remove the masking material (not
included) until the paint is completely dry.
4. Do not reattach the speaker to the bracket
until the bracket is mounted. Try to handle
any freshly painted parts as little as possible.
PAINTING THE GRILLE
1. Atrium loudspeaker grilles have an even,
protective powder coating. This powder
coating is an ideal primer. The grille has
a logo pod, which you may mask off
or paint right over.
2. Using spray paint, spray two thin coats
of finish color [figure 9]. If you’re using
a compressor and spray gun, use the finest,
most diffuse setting. Be careful not to fill
the holes in the grille with paint.
3. When the paint is completely dry, carefully
fit the grille into its recess so that it just rests
on the cabinet. Starting with one corner, work
around the speaker and push the grille into
the grille notch a little at a time.
Be gentle; the grille may be easily bent
by rough handling.
