PLACEMENT OPTIONS
The Atrium has a wide dispersion pattern,
and is very efficient. Your Atrium Series
speakers will deliver good sound quality
throughout a large listening area, but if you
really want high sound levels in an outdoor
setting, which has acoustic characteristics
that differ from those of indoor conditions,
we recommend multiple-pair setups.
You will maximize the useful life of your
Atrium speakers by placing them where they
will receive less exposure to the elements.
Look for the best overall compromise
between sound quality, convenience
and exposure.

PAINTING YOUR ATRIUM AW
LOUDSPEAKERS
PREPARING TO PAINT:
1. Separate the parts of the speaker. Remove
the brackets and bracket knobs. Remove
the grille by carefully hooking it with a
bent paper clip and pulling it gently away
from the cabinet [figure 4].
You will need:
• A spray can of primer paint (Krylon
Sandable Spray Primer #1318)
• A spray can of the paint of your choice.
Choose exterior grade paint if you
plan to use the speakers outdoors
2. Mask off the binding posts on the back
of the speaker [figure 5], the end panels
and bracket knobs, and carefully mask off
the front of the speakers to protect the dri-
vers and baffles while painting [figure 6].
The grille features an engraved logo pod.
You can mask this off or paint right over it.
• A paperclip or corkscrew (for removing
the paintable grille)
• Masking tape
• Paint mask (to cover unpaintable parts—
not included. To make an easy paint mask,
use the grille as a template and cut a mask
from heavy, nonporous Kraft paper.)

PAINTING THE CABINET, BRACKET
KNOBS AND BRACKET:
PAINTING THE GRILLE:
1. The grille of the Atrium speaker features
an even, protective powder coating.
1. Apply two thin coats of primer to the
cabinet and knobs. The bracket does not
require a primer.
This powder coating is an ideal primer.
The grille features an engraved logo pod.
You can mask this off or paint right over it.
2. When the primer is completely dry, apply
the finish color [figure 7].
2. Using spray paint, spray two thin coats of
finish color with no primer [figure 8]. 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, remove
the masking material.
4. Do not reattach the speaker to the bracket
until the bracket is mounted. Try to keep
all handling of freshly painted parts to
a minimum.
3. When the paint is completely dry, carefully
fit the grille into its recess so that it is just
resting on the cabinet. Starting with one
corner, go around the speaker and push
the grille into the grille notch a little bit at
a time. Be gentle; the grille may be easily
bent out of shape by rough handling.

MOUNTING
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, or by leaving the
bracket connected to the speaker [figure
9]. Orient the bracket so that the small
ends of the keyhole slots are facing “up”
according to the direction of installation.
Reattach the bracket to the speakers, if
you have removed it, by reinserting it into
the bracket gap and then tightening the
bracket knobs.
The Atrium’s bracket allows it to be mounted
either horizontally or vertically and aimed to
deliver the best possible sound in a variety
of situations. Follow the steps below to safely
secure the brackets and speakers.
Installation of 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.
1) Make sure the material on which you
plan to mount the speakers (plaster,
drywall, paneling, stone, etc.) can
support the weight of the speakers
(Atrium50=approx 5lbs/2.3kg ea,).
5) If you are certain that there is a stud
behind the wall surface, drive #10 screws
(not included) through the wall and into
the stud [figure 10a].
2) Make sure the locations you select do not
conceal electrical wiring or plumbing.
6) If there is no stud behind the wall at the
chosen location, install #10 wall anchors
(not supplied) into the wall by following
the wall-anchor-manufacturer’s instruc-
tions. Always use two wall anchors and
two screws per speaker [figure 10b].
3) Prior to installation, hold the speaker in
the chosen location to make sure it safely
clears obstacles such as ceiling, adjacent
walls, corners, beams, lighting fixtures
and door/window frames.
7) Drive screws into stud or wall anchors,
leaving screw heads protruding 1/16"
(1/6mm).

8) If speaker wire is being fed from a hole
in the wall behind the bracket, pull this
speaker wire through the hole in the
bracket before mounting the bracket
[figure 11].
13) Once the speaker is mounted, the bracket
knobs can be loosened to “aim” the speak-
er, and then hand-tightened to keep the
speaker angled correctly [figure 13].
14) Follow the hookup directions included
with your receiver. Strip 1/2 inch of insu-
lation from each of the two conductors
of the wire to expose the bare metal and
twist each of the conductors into a single
unfrayed strand (so you have two

speaker, so that the screw heads pass

slot [figure 12].
unfrayed strands). Note that one of the
terminals on the rear of each speaker is
red (+) and the other is black (-). Make
certain that you connect the wire from
the red terminal of your amplifier or
receiver to the red terminal on your
speaker and the wire from the black
terminal of your amplifier or receiver
to the black terminal on your speaker
[figure 14]. Most wire has some
11) Tug gently on the speaker to make certain
that the screws and bracket are properly
aligned and that the wall anchors
are secure.

the wall by the screw heads, remove the

in a little further and then remount

ALTERNATE SECURE MOUNTING
SAFETY FIRST
For more solid mounting, screw the bracket
directly into a weight-bearing stud on the
mounting surface.
When installing Atrium speakers be aware
of the weight of your particular model
(Atrium50=approx 5lbs/2.3kg ea,) and the
weight bearing tolerance of the material to
which you are mounting the speaker. If you
are not sure of a safe way of mounting your
speakers please consult a professional
installer, your authorized Polk Audio
dealer, or a building contractor.
Place the screws securely in the smaller
end of the keyhole slot. Do not leave
screwheads protruding.
Attach and remove the speaker from the
permanently secured bracket by tightening
and loosening the bracket knobs [as shown
in figure 13].
You will maximize the useful life of your
Atrium speakers by placing them where they
will 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. Do not compromise safety.
