Recommended speaker locations
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
®
20 music system
When you place your speakers according to the guidelines below, a combination of re-
flected and direct sound provides a good stereo image virtually everywhere in the room. You
may experiment with the placement and orientation of the Jewel Cube
TM
speakers and
Acoustimass
®
module to produce sound most pleasing to you.
To adjust your system for the characteristics of
your listening room, see “Fine-tuning your
system” on page 18.
Jewel Cube speakers
1. For the most lifelike sound, place the Jewel
Cube speakers 6-12 feet (1.8-3.6 m) apart.
They can be as close as 3 feet (1 m) or as far
apart as 15 feet (4.6 m).
2. Place the Jewel Cube speakers 6-12 inches
(15-30 cm) from the surface behind them.
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.
Note:
The Jewel Cube speakers are magnetically shielded so you can place them close to
a TV without affecting picture quality.
Acoustimass module
Follow these guidelines to select a location for the Acoustimass module.
1. Place the Acoustimass module along a side wall near the front of the room, if possible
(Figure 2). You can place the module along the same wall as the speakers, if more
convenient.
2. Aim the round opening (port) along the wall, 2 feet (.6 m) from a corner (Figure 2). Avoid
blocking the port.
3. Select a convenient location – under a table, behind a sofa. Do not allow furniture or
drapes to block the ventilation openings on the module.
4. Place the Acoustimass module within reach of the audio input cable, speaker cables,
and an electric outlet.
5. For proper ventilation, place the Acoustimass module on its long side, with the connec-
tors facing the floor (Figure 3). Or place it on its largest side, with the bass and treble
controls facing up. Do not place the module on either end.
6. Once you have selected a position for the Acoustimass module, place the four self-
adhesive rubber feet near the corners of the bottom surface. On a bare floor, the rubber
feet provide increased stability and protection from scratches.
7. For best bass performance, do not place the module midway between any two walls.
Note:
To avoid interference with the TV picture, keep the Acoustimass module at least 18
inches (45 cm) from any TV.
Music center
Select a location for the music center.
1. Place the music center on a level surface and allow enough room to lift the door.
2. Make sure it is close enough to any additional sound sources (TV, VCR, etc.) to allow for
cable length.
3. Keep the music center within 30 feet (9.1 m) of the Acoustimass module (the length of
the audio input cable).
