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 amplierto-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 amplier/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 dierentiated 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 amplier should be clear and •
unobstructed. Conrm placement for a wall port close to the intended
location of the amplier or receiver.
Label speaker wires at each end with Left and Right and the room location. •
Impedance Matching for Ampliers and Speakers
Not all ampliers 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
amplier 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/bae portion installs with a simple
twist. The Twist & Tilt technology oers the option of tilting the driver/bae
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
conguration 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.
