To create speakers this small, the magnet inside is formed using the rare earth element
neodymium and has ten times more energy (per unit volume) than conventional magnets.
For high performance from such a small package, a port 3.8 inches (9.7 cm) long was
designed in the shape of a nautilus shell and enclosed inside the tiny cube.
These, and numerous other innovations, bring you the Lifestyle
® 20 music system, offering

•Capability for operating two listening zones
Your Lifestyle
® music system offers several ways to listen to superbly reproduced sound.
You can use its built-in sound sources, connect additional equipment such as a tape deck,
laserdisc player, VCR, or TV, and use two listening zones.
Please take the time to follow this owner’s guide carefully. It will help you set up and operate
your Lifestyle
® music system, and enjoy all of its advanced features. Save your owner’s
guide for future reference.

Figure 2
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).

Setting Up
Connect the speakers and Lifestyle® music center
Once you have selected locations for your speakers and music center, connect the system.
Connecting the Jewel CubeTM speakers to the Acoustimass® module
1. Insert the connector of each speaker cable fully into the jack on the rear of each speaker
(Figure 4). Match the ridge of the connector to the notch at the top of the jack.
2. Connect each 20-foot (6.1 m) cable to the corresponding left or right green jack on the
Acoustimass module. Speaker cables have green connectors at one end, with L (left)
and R (right) molded into the connectors.
To lengthen the cable, connect speaker wire with male phono (RCA) plugs on each end to
your supplied speaker cable. Use a female-to-female adapter (“barrel” connector). Or, splice
in 18-gauge (.75 mm
2) or thicker cord (connecting + to + and – to –). To purchase extension
wire, see your dealer, electronics store, or call Bose® customer service.
Connecting the Acoustimass module to the Lifestyle® music center
Connect the Acoustimass module to the music center with the audio input cable (Figure 5).
1. Plug the small black multi-pin connector into the jack marked SPEAKER ZONE 1 on the
back of the music center.
2. Insert the right-angle multi-pin connector on the other end of the audio input cable into
the AUDIO INPUT jack on the Acoustimass module. Align the connector at the angle
shown in Figure 5.
Note: Be sure that each connector is inserted completely into each jack.
3. Extend the audio input cable as much as possible, since it includes an antenna for the
remote control.
For information on connecting zone 2, see “Using two listening zones” on pages 19-20.
CAUTION:
Make sure all components of
your system are unplugged
from the AC power (mains)
source before you begin
connecting them.
