INTRODUCTION
Introduction
Thank you for selecting the Russound Acclaim 7 Series In-ceiling Speakers.
Like all Russound speakers, they combine acoustic technology with durability
and will provide years of musical enjoyment. The Acclaim line provides
solutions for background music, dedicated music listening and home theater.
The 7 Series combines premium acoustic materials, with our most advanced
drivers to deliver exceptional performance in every application. From
background music to spectacular surround sound, Acclaim speakers oer the
nest sound around.
Twist & Tilt™ technology allows Acclaim ceiling speakers to deliver the best
direct listening performance by modifying their dispersion angle 15°, to focus
sound on the prime listening area. For general background sound delivery,
Twist & Tilt speakers can be set for uniform dispersion, lling the room with
excellent sound. This ability to focus the sound where you want it most
provides increased location exibility with heightened delity. Better attention
to aesthetic location is now possible, without compromising performance.
In addition to Twist & Tilt focused dispersion and easy mounting features,
Russound Acclaim 7 Series speakers feature high quality drivers, sophisticated
crossover networks, and advanced designs to ensure optimum reproduction in
your home, no matter what the source material may be.
Several models oer Treble and Bass frequency adjustment switches. This
adjustment allows you to tailor the sound of the Acclaim speakers to better
match the listening environment. The three-position switches oer +3dB,
-3 dB, and 0 dB settings. They are located on the front bae of specic models.

PREPARATION / WIRING INFO
Speaker Wire
The amount of wire needed varies with speaker placement. Label speaker
wires with left, right, and room location.
What kind to use: We recommend using Russound AW series speaker cable
or any reputable brand of 16 to 12 gauge multi-stranded wiring for amplier-
to-speaker connections.
Selecting the proper gauge: Wire is measured in gauges: the bigger the
number, the smaller the wire. The gauge of wire needed is determined by the
distance between your amplier/receiver and the speakers. The longer the
run, the heavier the gauge needed. Use the following chart as a guide:
Length Minimum Gauge
0' to 100' 16
50' to 150' 14
100' to 200' 12
If the conductors are not sheathed in colored jackets, be consistent with
usage. The standard colors on the terminals are red Positive (+) and black
Negative (-). If the wire has transparent insulation, one conductor will be
copper-colored (+) and the other silver-colored (-). If the wire has an opaque
insulation, the conductors are dierentiated by a series of ribs or grooves, a
stripe, or dotted line on one conductor. Use and mark these as the Positive (+)
conductor.
Installation Tips
When installing the speakers, avoid:
T-bar "drop ceilings" with very thin berboard panels which can buzz and•
vibrate. If needed, reinforce the drop-in panel with wood or particle board.
Ceilings where there are pipes, heating ducts and especially AC wiring in•
the general vicinity.
Speaker Wire Paths
Avoid running speaker wires close to house electrical wiring for any•
distance. If you have to run them parallel, leave two feet between the
wiring. Speaker wires should cross AC lines at a 90° angle.
The entire path between speakers and amplier should be clear and•
unobstructed. Conrm placement for a wall port close to the intended
location of the amplier or receiver.
Label speaker wires at each end with Left and Right and the room location.•
Impedance Matching for Ampliers and Speakers
Not all ampliers or receivers can safely operate two sets of speakers at once.
If you intend to use more than one pair of speakers at a time it’s important
to consider both the impedance of the speakers and the capabilities of the
amplier or receiver you’re using. Turning the bass frequency adjustment
switch from +3 dB, to 0 dB, to -3dB will change the impedance from 4 ohms, to
5 ohms, to 6 ohms respectively.

PREPARATION / SPEAKER PLACEMENT
Use and Placement
Determine the intended use and placement of the speakers in the room.
If they are going to be your primary listening source in a room, you need
to consider some other factors to insure proper imaging. The term "stereo
imaging" refers to a speaker system’s ability to project music so that it sounds
like the performers are in a three-dimensional space between the speakers.
The Acclaim Twist & Tilt speaker design provides the option of either uniform
or focused dispersion, ensuring that high quality sound lls the chosen
listening area. This ability to focus the sound where you need it most provides
increased exibility with heightened delity.
After the frame is secured, the speaker/bae portion installs with a simple
twist. The Twist & Tilt technology oers the option of tilting the driver/bae
assembly 15° to focus the sound towards the chosen listening area. A zero° tilt
allows for uniform dispersion.
Focused dispersion - using 15° tilt Uniform dispersion - using 0° tilt

PREPARATION / SPEAKER PLACEMENT
Speaker Placement in the Room
Bass frequencies are emphasized when ceiling speakers are placed close to a
wall. Avoid placing one speaker in a corner and another on a long at surface.
The best acoustic performance will result if both speakers are placed in similar
positions and face a similar type of surface.
The ceiling surround speakers should be placed directly to the sides or
rear of the prime listening position, but be aimed toward the listener. This
conguration is also suitable for a TV/movie and music mixed use.
If the prime purpose of the surround system is to listen to music, the ceiling
speakers should be aimed at the prime listening position.
Acclaim In-ceiling speakers may be used for rear surround sound channels
by placing them just behind the viewers. Refer to the 5 channel placement
diagram.
Refer to the details at right for sample In-ceiling placement options.
Good placement for serious listening:• Stereo pair In-ceiling. 6' to 8'
(1.8m-2.4m) apart, on the long wall of a rectangular room, centered on the
listening area.
Best placement for serious listening:• Stereo pair In-ceiling. 6' to 8' (1.8m-2.4m)
apart, on the short wall of a rectangular room, centered on the listening
area.
Good placement for background listening:• Stereo pair behind, above or to
the sides of the main listening area. 6' to 8' (1.8m-2.4m) apart, centered on
the listening area.
Surround sound:• The multiple surround locations can all be made to work
as long as the speakers are properly directed. The ceiling speakers should
be directed so that the sound is aimed toward the listener.

PREPARATION FOR INSTALLATION
Pre-wire or Pre-construction
Locate all obstructions (AC wiring, plumbing, duct work, studs, and joists).
Route the speaker wire to the speaker location avoiding all obstacles.
Russound oers Speaker Rough-In Brackets that can be fastened to the
adjacent studs. Once the dry wall is installed, the opening is cut out. There are
holes molded into the bracket for speaker wire tie-o to keep the wire from
being lost during construction.
Make sure the speaker cutout (hole) doesn't extend further than ¼" (0.6 cm)
from the inside of the mounting bracket.
Retrot Installation
Locate existing pipes, duct work, and AC wiring before cutting any holes in
the ceiling.
Center the cardboard template between adjacent joists, avoiding all wiring,1.
pipes, duct work, and lightly mark the outline with a pencil. Then use a
keyhole/drywall saw or motorized spiral-cut tool to make the opening.
Score the outline of the template with a utility knife to prevent chipping.2.
If dealing with lath and plaster or thick paneling, drill 1" (2.5 cm) holes in
several places around the pencil outline. Use a ne-toothed keyhole saw
or hacksaw blade with slow strokes to saw through and remove the inner
surface.
Run two pair conductors for single point speakers.

Painting the Speaker Frame and Grille
Russound Acclaim Speakers have a designer white nish that can be painted
with ordinary latex paint. Remove the speaker bae before painting.
Remove the speaker grilles. From the back of the speaker, push the clamp1.
(dog-ear) towards the grille to loosen it so you can pull it o. If the speaker
is already installed use a slightly bent paperclip to remove the grille.
Twist and remove the bae from the frame. Remove the scrim cloth from2.
the grille and set aside.
Paint the outer speaker frame and grille separately. Use the same coverage3.
on both the grille and frame. Russound recommends diluting the latex
paint with water 4:1 or 5:1 proportionally.
While the paint is still wet on the grille, and the grille is not in the frame, use4.
a gentle burst of compressed air against the outside surface to clear the
ne holes in the mesh.
After the paint has thoroughly dried, continue with the installation.5.
PREPARATION FOR INSTALLATION
Additional Tips / Considerations
If possible, run speaker wires after AC wiring is in place to avoid induced•
hum caused by close parallel proximity of the two types of wire.
Secure speaker wires in place against a stud along vertical runs with•
insulated staples only. Do not pierce the wire insulation. Allow a bit of slack
for expansion of building materials.
Route horizontal wire runs through holes drilled in studs at roughly equal•
heights.
The speakers should not be installed until the wallboard is in place. In the•
meantime, leave several feet of wire coiled up and secured to the back
side of the mounting frame. Excess length can be removed during nal
assembly.
When installing the drywall, make sure the speaker cutout hole doesn’t•
extend farther than ¼" (0.6 cm) from the inside of the mounting frame.
Any speaker installed in a ceiling should have a safety wire rmly tied•
between the back of the speaker assembly and the frame of the building.
Use any strong insulated wire and connect it to the speaker frame or bae,
being careful not to let it interfere with the speaker’s operation. The other
end should be rmly attached to the joist or ooring above using a hook,
nail, or other reliable fastener.
Terminate the wires in an outlet box attached to a stud or retrot junction•
box at the exit location. Utilize an outlet plate which has connections for
speaker wire terminations. Russound dealers oer a full line of Russound
PlateMate™ connection systems.
After the drywall is secured and nished, install the speakers as described•
in this manual.
