Before deciding where to place your speakers, survey your room and think about placement, using the
illustration below as a guide.
• Avoid placing the speakers near power amplifiers, heat
registers or other objects that generate large amounts
of heat.
• Do not place the speakers in very humid or dusty places.
• Do not place the speakers in direct sunlight or where they
will be exposed to other intense light.
• For best results, place the speakers 6–8 feet (1.8-2.4m)
apart. If you set the speakers farther apart than this,
angle them toward the listening position.
• The speakers will produce the most accurate stereo
soundstage when the angle between the listener and the
speakers is between 40 and 60 degrees.
• Generally, bass output will increase as the speaker is
moved closer to a wall or corner. For best performance,
we recommend that you place the speakers at least 20 inches (50cm) away from the sidewalls.
• The speaker will yield the best stereo imaging when oriented vertically.
• The L82 Classic may be stand mounted with optional JBL metal stands (model JBL JS-80,
sold separately) that angle the speaker upward.
• If not using the optional stands with built-in angle, then we recommend you to position each speaker
so that its tweeter is approximately at ear level.
Thank you for purchasing the L82 Classic 2-Way Loudspeaker
For more than 70 years, JBL has been providing audio equipment for concert halls, recording studios and
movie theaters around the world and has become the trusted choice of leading recording artists and sound
engineers. The legendary JBL 4310 professional studio monitor helped produce many of the most popular
albums of the 1960s and ‘70s. The 4310 was the inspiration for the L100 home audio loudspeaker introduced
in 1970, which became JBL’s all-time best selling speaker. The L82 Classic is a new model, re-interpreting the
classic JBL 8" 2-way in a modern, L100 Classic-styled system.
The new L82 Classic honors the storied legacy of the many historic JBL 8" 2-way speakers with its iconic 8-inch
(200mm) 2-way configuration, but with all new drivers, crossover network, enclosure, and features to bring the
design up to the highest 21st-century performance standards. Utilizing a compact footprint, the L82 Classic
features advanced JBL transducers including the JW200PW-6 Pure Pulp cone woofer, the JT025TI1-4 Titanium
tweeter.
The L82 Classic improves upon the performance of past JBL 8" 2-way models, back to the '70's, with its
exceptional dynamic range and contrast, clean and effortless high output, and precise high impact bass. With its
modern design, the L82 Classic has great detail resolution across the full bandwidth, very low distortion, and very
lifelike on- and off-axis stereo imaging, justifying its place as the smaller brother to the L100 Classic. The L82
Classic is sure to become a new legend among music lovers everywhere.

PLACEMENT AND POSITIONING
CAUTION: The L82 Classic weights 29 lb (13.2 kg) each. Before placing the speaker on a shelf or
platform, be sure that it is sturdy enough to support the speaker’s weight.

CONNECTIONS
BASIC SINGLE-WIRE CONNECTION
USING BARE WIRE OR PIN CONNECTORS:
USING SPADE CONNECTORS:
USING BANANA CONNECTORS:
IMPORTANT: Make sure that the (+) and (–) wires or
pins do not touch each other or the other terminal.
Touching cables can cause a short circuit that can
damage your receiver or amplifier.
IMPORTANT: Make sure the (+) and (–) spade connector
blades do not touch each other or the other terminal.
Touching blades can cause a short circuit that
can damage your receiver or amplifier.
CAUTION: Make sure that all of the system’s electrical components are turned OFF (and preferably
unplugged from their ac outlets) before making any connections.
Speakers and amplifiers have corresponding positive and negative (“+” and “–”)
connection terminals. The L82 Classic has color-coded connection terminals. The
“+” terminal is red, while the “–” terminal is black. See the illustration on the right.
The L82 Classic is designed so that a positive voltage at the “+” (red) terminal
will cause the speaker drivers to move outward (toward the room).
We recommend using a high-quality speaker cable with polarity coding. The side
of the wire with a ridge or other coding is usually considered positive polarity (“+”).
To ensure proper polarity, connect each “+” terminal on the back of the amplifier
or receiver to the respective “+” (red) terminal on each speaker. Connect the “–”
(black) terminals in a similar way. See your receiver or amplifier’s owner’s manual
to confirm its connection procedures.
Connect the amplifier to each speaker as shown in
the illustration on the right.
IMPORTANT: Do not reverse polarities (i.e., “+”
to “–” or “–” to “+”) when making connections.
Doing so will cause poor stereo imaging and
diminished bass performance.
The L82 Classic’s gold-plated speaker terminals
can accept a variety of wire connector types:
bare wire, spade connectors, pin connectors
and banana connectors.
L82 Classic Owner’s Manual

The L82 Classic has front-panel adjustments that let you balance
the levels of the tweeter (HF) relative to the woofer.
You can use these controls to adjust the speaker’s sound according
to your room’s acoustics, or your personal taste. The “0dB” default
position is a good place to start. Whatever sounds best to you in
your room is the right setting.
As with most speakers, after you start playing the L82 Classic it
will take the drivers’ suspensions several weeks to “break in” and
achieve optimum performance. During this period, the balance
between the tweeter may change, so we recommend that you
adjust the tweeter controls again after the break-in period.
NOTE: There is a protective plastic film on the front control panel label that may be removed.
• Wipe the cabinet with a clean, dry cloth to remove dust. Damp cloths or cleaning paper may dull the
cabinet’s finish.
• Do not use volatile liquids such as benzene, paint thinner, alcohol, etc., on the cabinet. Do not spray
insecticide near the cabinet.
• To remove dust from the foam grille, use a vacuum cleaner set to low suction.
• Do not wash the grille in water.
• If the surfaces of the woofer and midrange cones become dusty, you can carefully sweep them
clean with a soft, dry calligraphy brush or paintbrush. Do not use a damp cloth.
• NEVER touch anything to the tweeter dome.
