These speakers are designed specifically for use with the Bose Lifestyle® music systems to deliver high-fidelity, room-filling sound to additional rooms in your home. Because these speakers are different from other systems, we recommend that you take the time to read this owner's guide. It contains instructions and information that will help you get the most enjoyment possible from your new speakers. Unpacking the carton Carefully unpack your speakers. Save all packing materials for possible future use. The original packing materials provide the safest way to transport your speaker system. If any part of the product appears damaged, do not attempt to use the system. Notify Bose or your authorized Bose dealer immediately. Check to be sure your Acoustimass 5 or 20 powered speaker system contains the parts identified in Figure 1.

Then write them on your warranty card. WARNING: The Acoustimass module weighs 33 pounds (15 kg). Use good lifting practice to avoid injury. WARNING: To avoid danger of suffocation, keep the plastic bags out of the reach of children. 4 Setting Up Select the location for your speaker system When you place your speakers according to the guidelines below, a combination of reflected and direct sound provides a good stereo image virtually everywhere in the room. You may experiment with the placement and orientation of the cubes and the Acoustimass® module to produce the sound most pleasing to you. To adjust your system for the characteristics of your listening room, see "Fine-tuning your system" on page 14. English Speaker locations Follow these guidelines to select locations for your Acoustimass 5 or 20 speaker system. The speaker cables allow up to 20 feet (6.1 m) distance from the Acoustimass module. 1. For the most lifelike sound, place the cube arrays 6-12 feet (1.8-3.6 m) apart. They can be as close as 3 feet (0.9 m) or as far apart as 15 feet (4.6 m). 2. Direct one cube of each array forward. Direct the other cube toward the wall or in a different direction to create reflected sound. (See the illustration of reflected sound patterns in Figure 2.) Figure 2 Recommended speaker locations Left speaker Right speaker Acoustimass module CAUTION: Choose a stable and level surface for your speakers. Vibration can cause the speakers to move, particularly on smooth surfaces like marble, glass, or highly polished wood. For additional stability, you can add rubber feet to your speakers. You may obtain rubber feet (part no. 178321) free of charge from Bose®. Contact Bose Customer Service for more information. Note: If you put the speakers in a bookcase unit, be sure to place each one at the front edge of the shelf. Placing speakers in an enclosed space can change the tonal quality of the sound. This effect is minimized if the shelves are filled with books. Note: The cube speakers are magnetically shielded so you can place them close to a TV without affecting picture quality. 5 Setting Up English Select the locations for your speaker system (cont.) Acoustimass® module location Follow these guidelines to select a location for the Acoustimass module. 1. Place the module along the same wall as the speakers, if possible. 2. Select a convenient location ­ under a table, behind a sofa. Do not allow furniture or drapes to block the ventilation openings of the module. 3. Place the module within reach of the audio input cable, speaker cables, and an AC power (mains) outlet. 4. Select a position for the Acoustimass module (Figure 3). For proper ventilation, place it on the long edge, with the connectors facing the floor. An alternate position is on its largest side, with the bass and treble controls facing up. Do not place the module on either end, as shown by the last two views in Figure 3. Figure 3 Acoustimass module positions Preferred position Alternate position 5. Once you have selected a position for the module, place the four self-adhesive rubber feet near the corners of the bottom surface. The rubber feet provide increased stability and protection from scratches. 6. Aim the port (the round opening) into the room or along the wall to avoid blocking the port or creating too much bass. 7. For best bass performance, do not place the port at equal distances from any two walls or from a wall and the ceiling. Before making connections, unplug your system It is important that you unplug your Lifestyle® system or other music source before making any connections. Selecting the correct voltage If you purchased a dual voltage product, please be sure that your speakers are set to the correct voltage for your geographical area. Use the adapter plug provided when appropriate. Figure 4 Voltage selector switch settings CAUTION: Do not cover the ventilation openings of the Acoustimass module. The slots on the end provide ventilation for the built-in electronic circuitry, and should not be blocked. Note: To avoid interference with the TV picture, place the Acoustimass module at least 18 inches (45 cm) from a TV. 6 Setting Up Connect the speakers and the Acoustimass® module Connecting the Acoustimass 20 Jewel Cube® speakers to the Acoustimass module 1.
