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.

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).
