Setting Up
CAUTION:
Choose a stable and level
surface for your Jewel Cube
speakers. Vibration can cause
the speakers to move, particu-
larly on very smooth surfaces.
For stability, peel off the
backing from the rubber feet
and center them in the
matching shapes on the
bottom of each speaker.

Select the locations for your Lifestyle
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 Jewel Cube
Acoustimass
®
module to produce 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.
Jewel Cube speaker locations
Follow these guidelines to select locations that provide the maximum home theater effect
from your Lifestyle

30 system (Figures 2 and 3). Place each of the Jewel Cube speakers
6-12 inches (15-30 cm) from the surface behind them.
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 speaker toward the center of the room (Figure 2). Direct the
other cube toward a side wall to create reflected sound. (See the illustration of sug-
gested reflected sound patterns in Figure 3.)
Note: The Jewel 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.
Note: Do not place the speaker on its side, as this diminishes performance by blocking the
Jewel Cube ports.
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.
