Setting Up
Before you begin
We appreciate your choice of the Bose® Acoustimass® 6 Series III or Acoustimass 10 Series III
home entertainment speaker system.
Bose Virtually Invisible® speaker technology allows you to enjoy lifelike home performances
from the very latest surround-sound encoded movies, CDs, and television shows, without a
room full of speakers. The cube speakers, along with the powered Acoustimass module,
reproduce the full-spectrum of sound from multi-channel digital programming. Integrated Signal Processing assures full bass performance from all channels, at audible listening levels,
regardless of your receiver settings.
Your stereo VCR, stereo television, or DVD player sends the encoded program material to the
surround-sound receiver, which interprets and distributes the information to the powered
Acoustimass module. The module delivers the bass for all channels and sends appropriate
sounds to each cube speaker. The sound mix varies with different program types: dialogue is
usually sent to the center cube speaker, a visual soundstage is created by the left and right
front cube speakers, and you feel as if you are in the center of the action because sounds and
special effects are directed to the rear cube speakers. At a given point in a surround-sound
performance, you may hear sound from one, a few, or all of the cube speakers.
To select surround-encoded program material, look for the terms Surround, Dolby Surround,
the double-D symbol 3, Dolby Digital 1, other digital formats, or the word “surround” preceding a TV broadcast. Your system is compatible with home theater receivers.
You can also enjoy a wide variety of stereo programming that is not surround-encoded.
Unpacking the carton
WARNING: The powered Acoustimass® 6 module weighs 27 pounds (12.3 kg). The powered
Acoustimass 10 module weighs 35 pounds (15.9kg). Use good lifting practice to avoid injury.
WARNING: To avoid danger of suffocation, keep the plastic bags that wrap these speakers
out of the reach of children.
Note: This product is not to be powered by any DC-to-AC inverters that may be found in
automobiles, recreational vehicles, boats, ships, or other similar situations.
Carefully unpack the carton contents (Figure 1):
1.
Remove the brown inner carton containing the cube speakers.
2.
Gently roll the carton over onto its side.
3.
Slowly pull the Acoustimass module from the carton.
4.
Gently stand the module up.
Note: Now is a good time to record the serial number of these speakers on your warranty
card. Please save all packing materials for possible future use.

Placing your speakers to achieve realistic home theater sound
A suggested home theater layout is shown in Figure 2. You may want to place the speakers
differently to take advantage of the sound characteristics of different rooms. Here are some
suggested guidelines for placing your speaker system:
• The cube speakers are identical and can be used for any channel.
• Each of the Acoustimass cube speakers is magnetically shielded to prevent interference
with a TV picture.
• In the Acoustimass 10 system, the top and bottom sections of the cube speaker arrays can
be rotated to create room-filling sound patterns (Figure 3).
• Bose® wall brackets and floor stands can extend your placement options. See “Accessories” on page 17. Please follow wall bracket instructions carefully. Proper mounting will
ensure optimum performance and safety from your system.

Room reflection diagram
Front center cube speaker
The front center cube speaker localizes action and dialogue on your screen. Sound should
seem to come from within the picture.
• Place the front center cube speaker above, below, or on top of your television. If below, be
sure that it is not supporting the weight of the television in any way.
• Keep the front cube speaker as close to the vertical center of the screen as possible, for the
most accurate dialogue reproduction.
CAUTION: Choose a stable and level surface for your cube speakers. Vibration can cause
them to move, particularly on smooth surfaces like marble, glass, or highly polished wood. If
you are placing the center cube speaker on top of your television, use the set of four rubber
feet provided. You may obtain additional rubber feet (part number 178321-04), free of
charge, by contacting Bose® Customer Service. See the list of phone numbers included with
your system.

264887_00 _V.pdf • August 13, 2002
Setting Up
Front left and right cube speakers
The front left and right speaker arrays create a sound image wider than the screen that seems
natural to viewers sitting anywhere in the room. You can place the speaker arrays near a TV
screen with no picture interference. Place the front cube arrays on either side of your TV, at
least 6 feet (2 m), or as much as 15 feet (5 m) apart (see Figure 2).
Rear cube speakers
The rear, or surround, cube speakers add discrete sounds and special effects that expand the
visual image, bringing the viewer into the center of the action. The rear cube speakers may
carry dialogue as well.
• Position the left and right rear cube speakers to allow the sound to reach the viewer from
both sides, rather than from directly behind (see Figure 3).
• Place the rear cube speakers at ear height or higher, if possible.
• For the Acoustimass® 10 system, rotate the top and bottom sections of the rear cube
speaker arrays to direct the sound to the front and back of the listener (see Figure 3).
• For the Acoustimass 6 system, aim the rear cube speakers slightly behind the listener or
reflect the sound off the rear wall (see Figure 3).
Powered Acoustimass module
Bose® Acoustimass speaker technology takes advantage of the fact that the source of pure
bass sound is difficult to locate, so you can hide the powered Acoustimass module conveniently out of sight. Place the module at the same end of the room as the television monitor.
• You may hide the module behind furniture, but do not block the opening. Be sure there are
at least 2 inches (5 cm) between the opening and any surface.
• If the opening faces the wall it increases the bass; if it faces away it decreases the bass.
CAUTION: To prevent interference, keep the module at least 2 feet (.6 m) from your TV set.

Note: Placing the module horizontally, or on its
side, may reduce ventilation, inhibiting its ability to
play at full output for extended periods of time.

Checking the connections
Check all connections from the receiver to the powered Acoustimass® module and from the
module to the cube speakers (Figure 5 and Figure 6). Make sure the cube speakers are connected to the proper terminals according to their position in your room. Check that the wires
are connected to your surround receiver in phase (+ to + and – to –). Correct wiring problems
before you plug your receiver in and turn it on.
Connecting the Acoustimass module to power
Note: Bose® recommends using a quality surge suppressor on all electronics equipment.
Voltage variations and spikes can damage electronic components in any system. A quality
suppressor can eliminate the vast majority of failures attributed to surges and may be purchased at an electronics store.
After you have checked all system connections, plug the power cord of the powered Acoustimass module into an AC (mains) receptacle. Your Acoustimass speaker system will turn on
and off automatically as it receives a signal from your surround receiver.

264887_00 _V.pdf • August 13, 2002
Using your system
For realistic home theater sound
CAUTION: The Acoustimass® 6 and Acoustimass 10 speaker systems incorporate an automatic protection circuit, which guards against most kinds of damage from electrical stress or
overload. This circuit activates at high volume levels to reduce output, causing a slight
decrease in volume. This is normal operation and indicates that power input may be exceeding safe levels. Sustained listening at these levels is not recommended.
Adjusting the LFE level (low frequency effects)
LFE
S
BAS
LFE
BASS
LFE
The LFE level control on your powered Acoustimass module increases or decreases the relative level of low frequency effects on movie soundtracks. Use it to regulate the presence of
these underlying deep bass sounds. Use the “test tones” feature in your digital surround
sound receiver to match the volume levels for each of the cube speakers. Then use the LFE
control on the Acoustimass module to match the volume of the LFE channel to the cube
speaker channels.
Adjusting the bass/room compensation level
This feature will allow you to fine-tune your system after you have placed the Acoustimass
module in your selected location. If the room sounds “thin” or lacks bass, turn the BASS control in a clockwise direction to increase the bass level of the module. If the room sounds
“boomy” or has too much bass, turn the knob in a counter-clockwise rotation to reduce the
bass level of the module. The factory or detent setting is appropriate for a majority of listening
situations.
Setting your digital surround sound receiver
Your Acoustimass 6 or Acoustimass 10 speakers are compatible with the output from digital
surround receivers. Integrated Signal Processing assures full bass reproduction for all channels regardless of receiver settings. However, the following table suggests a set of recommended receiver settings. The cube speaker arrays should be set to LARGE in the receiver's
digital display menu. The LFE, or subwoofer, is set to ON. If applicable, the crossover value
should be set to the lowest number possible, typically 80 Hz.
