Setting Up
Selecting the locations for your Lifestyle® 25 Series II system
When you place your speakers according to the guidelines below, a combination of reflected and direct sound provides the audio atmosphere of a home theater. You may experiment with the placement and orientation of the cubes to produce the sound most pleasing to you. For more discussion of speaker placement and room acoustics, see
Speaker locations
Follow these guidelines to select locations that provide the maximum home theater effect from your Lifestyle® 25 system (Figures 2 and 3).
CAUTION: Choose a stable and level surface for your speakers. Vibration can cause the cube speakers to move, particularly on smooth surfaces like marble, glass, or highly polished wood. If you are placing the center speaker on top of the television, use the smaller of the two sets of rubber feet provided. You may obtain additional rubber feet (part no. 178321), free of charge, by contacting Bose® Customer Service (see listings on the inside back cover).
Left and right front speakers
The sound from the left and right front speakers should seem to appear at the edge of the picture, so that the acoustic image is close to the size of the visual image (Figure 2).
1.Place the cubes so that they line up with the center of the TV screen.
2.Place them up to 3 feet (1 m) from the edge of the TV screen.
We recommend a maximum distance of 3 feet (1 m) so that the sound does not become too separated from the picture. You may wish to vary this distance based on room condi- tions and personal preference. The front cables allow the cube speakers to be placed up to 20 feet (6.1 m) from the Acoustimass module.
3.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 pat- terns in Figure 3.)
Note: The cube speakers are magnetically shielded so you can place them close to the
TV without affecting picture quality.
Center speaker
The sound from the center speaker should appear to come directly from the center of the picture (Figure 2). The center speaker cable allows up to 20 feet (6.1 m) distance from the Acoustimass module.
1.Place the center speaker directly above or below the center of the TV screen, or at the closest convenient location.
2.Align the speaker with the front of the TV screen (not pushed to the back of the TV).
3.Direct each of the cubes slightly away from center, to create a wider area of direct sound (Figure 3).
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.
