WIRING THE SYSTEM
IMPORTANT: Make sure all equipment is turned off before making any
connections.
For speaker connections, use a high-quality speaker wire with polarity coding.
The side of the wire with a ridge or other coding is usually considered positive
polarity (i.e., +).
NOTE: If desired, consult your local JBL dealer about speaker wire and
connection options.
The speakers have coded
terminals that accept a variety
of wire connectors. The most
common connection is shown
in Figure 4.
To ensure proper polarity,
connect each + terminal on the
back of the amplifier or receiver
to the respective + (red)
terminal on each speaker, as
shown in Figure 5. Connect the
– (black) terminals in a similar
way. See the owner’s guides
that were included with your
amplifier, receiver and
television to confirm
connection procedures.
IMPORTANT: Do not reverse polarities (i.e., + to – or – to +) when
making connections. Doing so will cause poor imaging and diminished bass
response.

of a stereo or home theater system.
BI-WIRING
ES30, ES80, ES90, ES100
The outer connection panel and internal dividing network of the ES30, ES80,
ES90 and ES100 are designed so that separate sets of speaker cables can be
attached to the low-frequency transducer and midrange/high-frequency
transducer portions of this dividing network. This is called bi-wiring. Bi-wiring
can provide several sonic advantages and considerably more flexibility in
power amplifier selection.

FINAL ADJUSTMENTS
Check the speakers for playback, first by setting the system volume control
to a minimum level, and then by applying power to your audio system. Play
a favorite music or video segment and increase the system volume control
to a comfortable level.
NOTE: You should hear balanced audio reproduction across the entire
frequency spectrum. If not, check all wiring connections or consult the
authorized JBL dealer from whom you purchased the system for more help.
The amount of bass you hear and the stereo-image quality will be affected
by a number of different factors, including the room’s size and shape, the
construction materials used to build the room, the listener’s position relative
to the speakers, and the position of the speakers in the room.
Listen to a variety of music selections and note the bass level. If there is too
much bass, move the speakers away from nearby walls. Conversely, if you
place the speakers closer to the walls, there will be more bass output.
CARE OF YOUR SPEAKER SYSTEM
Each JBL ES Series enclosure has a finish that does not require any routine
maintenance. When needed, use a soft cloth to remove any fingerprints or
dust from the enclosure or grille.
NOTE: Do not use any cleaning products or polishes on the cabinet
or grille.
