Select the locations for your Lifestyle® 25 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 the best surround effect, adjust the speakers so you cannot identify the exact sound source. It is preferable not to aim the cubes directly at the listener. For more discussion of speaker placement and room acoustics, see “Fine-tuning your system” on page 22.

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 (see listings on the inside back cover).

Speaker locations

Follow these guidelines to select locations that provide the maximum home theater effect from your Lifestyle® 25 system (Figures 2 and 3).

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 them on line with the horizontal center of the TV screen.

2.Place each speaker 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 conditions 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 patterns 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 cable allows the center speaker to be placed up to 20 feet (6.1 m) from the Acoustimass module.

1.Place the speaker on line with the vertical center of the screen, above or below (which- ever is closer to the screen), or the closest convenient location.

2.Place the speaker in line with the front of the 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.
