Setting Up
Before you begin
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. Each of the five cube speaker arrays, along with the Powered Acousti-
mass® module, reproduces the full-spectrum of sound from multi-channel digital program-
ming. Integrated Signal Processing assures full bass performance from all channels, at all
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 array. The sound mix varies with different program types: dialogue is
usually sent to the center speaker, a visual soundstage is created by the left and right front
speakers, and you feel in the center of the action because sounds and special effects are
directed to the surround (rear) speakers. At any point in a surround-sound performance, you
may hear sound from one, a few, or all of the speakers.
To select surround-encoded program material, look for any of the terms Surround, Dolby
Surround, the double-D symbol
*, other digital formats, or the word “sur-
round” preceding a TV broadcast. Your system is fully compatible with the latest home
theater receivers. You can also enjoy a wide variety of stereo programming that is not sur-
round-encoded with your Acoustimass 15 speakers.
Unpack the carton
• Remove any staples from the opened carton flaps.
• Remove the brown inner carton containing the five cube speaker arrays.
• Gently roll the carton over onto its side and then onto its opening.
• Slowly lift the carton from around the Powered Acoustimass module’s packing cushions.
• Do not detach the removable cables connected to the Powered Acoustimass module.
• If the speakers or the module appear damaged, do not use them. Repack everything in
the original carton and contact your authorized Bose dealer immediately.
Note: Now is a good time to record the serial number of these speakers on page 2 of this
guide and on your warranty card. Please save all packing materials for possible future use.
WARNING: The Powered Acoustimass module weighs 33 pounds (15 kg). 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.

Setting Up
Placing your speakers to achieve realistic home theater sound
A suggested home theater layout that conforms to the guidelines described above is shown
in Figure 2. You may want to place the speakers differently, to take advantage of the sound
characteristics of different rooms.
Note: The cube arrays are identical and can be used for any channel. All of the cube arrays
are magnetically shielded to prevent interference with a television picture. Twist the cube
arrays so the speakers create room-filling sound patterns.
Note: Bose wall brackets and floor stands can extend your placement options. See “Acces-
sories” on page 13. Please follow wall bracket instructions carefully. Proper mounting will
insure optimum performance from your system.
Figure 2
One suggested home theater
layout
Center cube speaker
The center speaker localizes action and dialogue on your screen. Sound should seem to
come from within the picture.
• Place the center cube array 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 cube array as close to the vertical center of the screen as possible, for the most
accurate dialogue reproduction.
CAUTION: If you are placing the center cube array on top of the television, use the smaller
of the two sets of four rubber feet provided. This will provide extra stability on surfaces such
as marble or glass. Additional rubber feet are available, free, by calling the Bose® customer
service numbers inside the back cover of this manual. Ask for Part Number 178321-04.

Setting Up
Left and right front cube speakers
The left and right front speakers create a sound image wider than the screen that seems
natural to viewers sitting anywhere in the room. You can place them near a TV screen with no
picture interference. See figure 2.
• 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.
Surround cube speakers
The surround, or rear, speakers add discrete sounds and special effects that expand the
visual image, bringing the viewer into the center of the action. The surround speakers may
carry dialog as well. The surround speakers should be positioned to allow the sound to reach
the viewer from both sides, rather than from directly behind. See Figure 2.
• Place the speakers at ear height or higher, if possible
• Adjust the rear surround speakers to direct the sound to the front and back of the listener.
®
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 conve-
niently out of sight. Place the module at the same end of the room as the television monitor.
• You may hide the module behind or under furniture, but do not block the opening. Be sure
there is 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.
For the most bass response, place the opening 2 to 3 inches (5 to 8 cm) from a wall or
corner.
• You may stand the Powered Acoustimass module vertically or horizontally (Figure 3).
• After selecting a place for the module, attach the larger set of four rubber feet to the
bottom surface for additional stability.
CAUTION: To prevent interference, keep the module at least 2 feet (.6 m) from the televi-
sion.

Setting Up
Connect the speakers
Connect the cube arrays to the Powered Acoustimass® module, and then connect the
module to your receiver. The supplied cables make this easy. The cables may be separated
or “unzipped” as much as needed to comfortably reach the speakers. See Figure 4.
Figure 4
Separating cables
CAUTION: Before making any connections turn off your receiver and unplug it from the
outlet (AC power mains). Not doing so may result in damage to your system.
CAUTION: Never connect the cubes directly to a receiver output. Always connect the cube
arrays to the Powered Acoustimass module, then connect the module to the receiver.
CAUTION: Never use broken or frayed wiring, which can result in electrical shock or
damage to your system. The supplied cables are not intended for in-wall installation. Check
local building codes or enlist a qualified installer.
Connect the Powered Acoustimass module to the center and
front cube arrays
Three individual 20 (6m) foot wire pairs connect the Powered Acoustimass module to the
Center, Right, and Left front cube arrays. Each cable connects to the module with a single
plug.
1. Connect the wire pair marked C to the center speaker. Just press the terminal tab on the
back of the cube array to insert the marked wire into the red terminal and the plain wire
into the black terminal. See Figure 5. Release the tab to secure the wires.
2. Connect the wire pair marked R to the right front speaker (to the right of the TV as you
face it).
3. Connect the wire pair marked L to the left front speaker.

Connect the Powered Acoustimass module to the surround
cube arrays
The 50 foot (15 m) cable with two pairs of wires connects the Powered Acoustimass module
to the Right and Left surround cube arrays. Each has an individual plug on the module end.
1. The wire marked R connects the module to the right surround speaker (on your right as
you face the TV). As shown in Figure 5, press the terminal tab on the back of cube array to
insert the marked wire into the red terminal and the plain wire into the black terminal.
2. The wire marked L connects the module to the left surround speaker.
3. Insert the connectors firmly into their jacks at the Powered Acoustimass module.
Connect the Powered Acoustimass module to the receiver
The 20 foot (6m) cable with five pairs of wires and a single wire with an RCA plug connects
the module to the outputs on the receiver as shown in the table below.
Note: The RCA plug comes with a cover installed. Remove this cover for connection to the
LFE/SUBWOOFER OUT jack. If your receiver has no LFE/SUBWOOFER OUT jack, leave the
plug cover in place; in this case this wire will not be used.
• Match the polarity on the receiver. Connect the wire pairs in phase (+ to + and – to –).
a. Attach each marked wire (+) to the appropriate + terminal.
b. Attach each plain wire (–) to the appropriate – terminal.
• Connect the RCA plug to the receiver’s LFE/SUBWOOFER OUT jack.
• At the Powered Acoustimass module, be sure the receiver cable connector is firmly
