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.

Tiefen in einer Ecke an. Die Halterung wird an einer Seitenwand  
befestigt.

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).

Utilisez une vis no10 pour fixer le support dans un montant.  
Utilisez une cheville d'ancrage et une vis

Verwenden Sie eine Schraube Nr. 10 für Wände mit Holzstielverstärkung bzw. Dübel und  
Schrauben (Nr. 10) für Wände ohne Holzstielverstärkung.

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  
9) Line up the bracket, attached to the  
speaker, so that the screw heads pass  
through the large center hole of the  
bracket’s keyhole slots.

down, allowing the screw head to slip  
behind the smaller end of the keyhole  
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.  
12) If the bracket is not held snug against  
the wall by the screw heads, remove the  
speaker from the wall, drive the screws  
in a little further and then remount  
the speaker.

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.
