UNPACKING THE SPEAKERS
If you suspect damage from transit, report it immediately to your dealer.
Keep the shipping carton and packing materials for future use.
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.
Figure 1. Experiment with speaker placement to obtain
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. Since the speakers are
magnetically shielded, you can place them near the TV without worrying
about the field distorting the TV picture.
For surround-channel use, place speakers on bookshelves or stands
alongside the listening position. The ES10 is also wall-mountable. 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.
NOTE: A JBL powered subwoofer will add impact and realism to both
music and film soundtracks. Contact your JBL dealer for recommendations
on subwoofer models for your application.
Figure 2. This overhead view shows a typical home theater plan. Left/right
rear channels are for a 7-channel system. The center rear channel is for
a 6-channel system.
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.
