Setting Up Your Acoustimass® 3 Speaker System
Before you begin
Thank you for purchasing the Bose® Acoustimass® 3 speaker system. Its quality construction and advanced technologies result from years of ongoing research at Bose.
Bose patented Acoustimass speaker technology delivers full, natural audio performance and, for all of the sound it produces, this Virtually Invisible® system takes up very little space. The tiny cube speakers fit almost anywhere, while the Acoustimass module is designed to be hidden behind drapes, under furniture, or in the corner of the room.
Unpacking the system
Unpack the system carefully. Avoid setting the module down on its connection panel, which could scratch a surface. (Save the carton and packing materials in case you ever want to ship the system.) If any parts appear damaged, do not attempt to use the system. Repack all parts in the original carton and notify your authorized Bose dealer immediately.
Figure 1
What the carton contains
Acoustimass module
Two cube speakers
Four (4) adhesive-backed 
rubber feet
Four (4) speaker cables, 20 feet long
Selecting locations for the cube speakers
You can place the cube speakers anywhere from 3 to 15 feet (0.9 - 4.6 m) apart. For the most natural sound in average sized rooms, place them 6 to 12 feet (1.8 - 3.7 m) apart. Magnetic shielding allows you to place them close to a video screen without causing interference.
Bose mounting accessories, including wall/ceiling mounting brackets, floor stands, and table stands, add to your choice of where to place the cube speakers. For more information or to order accessories, contact your Bose dealer or call Bose Customer Service directly. Refer to the list of phone numbers inside the back cover.

Setting Up Your Acoustimass® 3 Speaker System
Selecting a location for the Acoustimass® module
The Acoustimass module can be hidden almost anywhere in a room. Leave at least 2 inches (5 cm) of space between the opening (port) and the wall. To prevent interference, keep the module at least 2 feet (0.6 m) from any video screen.
For a balanced sound in most rooms, place the module along a wall within 5 feet (1.5 m) of the corner. To increase bass response, move the module closer to a corner without blocking the opening. To decrease the bass, place the module farther from the corner.
Note: When you decide how you will position the module, attach the rubber feet to the bottom surface to protect the module and the floor.

Choices on how to position the module
Using the cables correctly
Use the supplied cables to connect the cube speakers to the module and the module to your amplifier or receiver.
CAUTION: Be sure all components are turned off and unplugged from the power outlet before making the connections.
To place these components more than 20 feet (6.2 - 9.2 m) apart, you will need to splice in a length of 18-gauge speaker cable. To place them more than 30 feet (9.2 m) apart, you will need heavier gauge wire. (See the wire recommendations on page 10.) You can get additional speaker cable at electrical and hardware stores or by calling Bose Customer Service. (See the list of phone numbers inside the back cover.)
Speaker cables consist of two insulated wires. The insulation around one wire is marked with a band or stripe. This marked wire is always positive (+). The plain wire is always negative (–). These correspond to the red (+) and black (–) terminals on the back of the speaker, amplifier, or receiver. Be sure to connect each wire to the proper terminal (positive to positive, negative to negative).
