OWNER’S GUIDE

JBL®LS SERIES

For more than 60 years, JBL, Inc. has been providing audio equipment for

concert halls, recording studios and movie theaters around the world and has

become the hands-down choice of leading recording artists and sound

engineers.

With the JBL LS Series, innovative technologies such as pure-titanium

compression drivers, Elliptical Oblate Spheroidal

™(EOS) waveguides and

Bi-Radial Horn®are available to you. Enjoy!

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.

INCLUDED

LS60, LS80

Spike kit (packed in end pads)

(4) coasters

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. 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.

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.

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 rubber-

tipped 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.

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.

STANDARD CONNECTION

Figure 5. Wiring diagram shows polarity connections for one channel

of a stereo or home theater system.

BI-WIRING

LS40, LS60, LS80

The outer connection panel and internal dividing network of the LS40, LS60

and LS80 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 LS 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.
