PLACEMENT

NEVER drag the speaker to move it, as this will damage the spikes, the

feet and/or the wood cabinet itself. Always lift the speaker and carry it to its
new location.

CAUTION: Floorstanding (tower) loudspeakers have a high center of
gravity and may become unstable and tip over during events such as
earthquakes, or if rocked, tipped or improperly positioned. If this is a concern,
these speakers should be anchored to the wall behind them, using the same
procedures and hardware customary for anchoring bookcases and wall units.
The customer is responsible for proper installation and proper selection of
hardware.

STEREO

Before deciding where to place your speakers, survey your room and think
about placement, keeping the following points in mind, using Figure 1 as a
guide:

• For best results, place the speakers 6'–8' (1.5m–2.5m) apart.

• Position each speaker so that the tweeter is approximately at ear level.

• Generally, bass output will increase as the speaker is moved closer to a wall
or corner.

• Refer to “Home Theater” below if you also plan to use the speakers for
home theater reproduction.

Listening Position

the best bass level and stereo imaging in your room.

HOME THEATER

For front-channel use, place one speaker on the left and another on the right,
along either side of the television monitor. The JBL LS speakers are primarily
designed for use with Plasma, LCD and DLP TV screens, and should not be
placed in close proximity of CRT (Cathode Ray Tube) TV sets.

For surround-channel use, place speakers on bookshelves or stands
alongside the listening position. Final placement depends on room acoustics,
availability of space and your listening preference (Figures 2 and 3).

In 6- or 7-channel configurations, place the rear channel(s) behind the
listening position, as shown in Figures 2 and 3.

Figure 3. This figure shows an alternate layout, which may be more suitable
for some rooms. Left/right rear channels are for a 7-channel system. The
center rear channel is for a 6-channel system.

INSTALLING SPIKED FEET

LS60, LS80

Four metal spikes are supplied for use when the speaker is to be placed on a
carpeted surface; using them decouples the speaker from the floor to prevent
unwanted damping. To insert the spikes, gently lay the speaker on its side (not
its front or back) on a soft, nonabrasive surface, and unscrew the rubber­tipped feet (store in a safe place). Each spike then screws into the threaded
insert in each corner. Make sure all four spikes are screwed in completely for
stability. To protect the surface of uncarpeted floors, set each spike into an
included metal coaster.

NEVER drag the speaker to move it, as this will damage the spikes, the feet
the wood cabinet itself and/or the floor. ALWAYS lift the speaker and
carry it to its new location.
