PLACEMENT AND POSITIONING

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, the 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.

CONNECTIONS

JBL L100 Classic 75 Iconic 3 Way Bookshelf Loudspeaker - fig3

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 11-“) connection terminals. The L100 Classic 75 has two sets of connection terminals; gold-plated jumper straps connect the terminals to each other. The terminals are marked “+” and “-.° Additionally, the “+” terminals have red rings, while the “2 terminals have black rings. See the illustration below.
We have designed the L100 Classic 75 so that a positive voltage at the “+” (red) terminal will cause the speaker transducers to move outward (toward the room). We recommend using a high-quality speaker wire with polarity coding. The side of the wire with a ridge or other coding is usually considered positive polarity (“+”). To ensure proper polarity, connect the left- and right-channel ‘+’ terminals on the back of the amplifier or receiver to their respective “+” (red) terminals on the speakers. Connect the “2 (black) terminals In a similar way. See the owner’s manual of your receiver or amplifier to confirm its connection procedures.

Connect the amplifier to each speaker as shown in the illustration below. You can use either set of terminals on the speaker.
NOTE: Do not remove the jumper straps from between the two sets of terminals when connecting the speaker wires.
IMPORTANT: Do not reverse polarities (i.e., ‘+” to “2 or °-” to “+”) when making connections. Doing so will cause poor stereo imaging and diminished bass performance. The L100 Classic 75’s gold-plated speaker terminals can accept a variety of wire-connector types: bare wire, spade connectors, pin connectors and banana connectors.
Using Bare Wire or Pin Connectors:
IMPORTANT: Make sure the (+) and (-) wires or pins do not touch each other or the other terminal. Touching wires can cause a short circuit that can damage your receiver or amplifier.
NOTE: Bare wire can also be wrapped around the terminal shaft and then the cap tightened to secure the wire.
CAUTION: Once the caps are tightened. make sure that the jumper straps are held firmly between the respective term’s. If they are loose. the speakers will not operate properly.
Using Spade Connectors:
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: Once the caps are tightened. make sure that the jumper straps are held firmly between the respective terminals. If they are loose, the speakers will not operate properly. Using Banana Connectors:
CAUTION: Be sure to lighten the caps to make sure that the jumper straps are held firmly between the respective terminals. If they are loose, the speakers will not operate properly.

BI-WIRE AND BI-AMP CONNECTION

JBL L100 Classic 75 Iconic 3 Way Bookshelf Loudspeaker - fig8

For either bi-wire or bi-amp operation, remove the jumper straps from the terminal cup of the JBL L100 Classic 75 loudspeaker and store in a safe place. Note that removing the straps only disconnects the inputs of the low frequency and high-frequency crossovers from each other. but keeps the full protections and frequency tailoring of the custom crossovers for the separate
CAUTION: Do not connect to your speaker in a bi-wire fashion with the jumper straps attached. Severe amplifier damage, personal injury, or damage to other property may result.
The L100 Classic 75 connection assembly has two sets of input terminals that are connected by jumper straps.
The upper set of terminals is for the tweeter, and the lower set of terminals is for the woofer.

BI-WIRE AND BI-AMP CONNECTION (continued)
Bi-wiring

JBL L100 Classic 75 Iconic 3 Way Bookshelf Loudspeaker - fig9
JBL L100 Classic 75 Iconic 3 Way Bookshelf Loudspeaker - fig10

An amplifier and speaker system are bi-wired when the high frequency and low-frequency inputs of the speaker are driven by two different wires from the same amplifier channel. Usually, different types of wire are used for the connections: a high-current-capability wire or a wire that sounds better to the user for bass is typically used for low frequencies, and a low-inductance wire or a wire that sounds better for treble to the user is used for high frequencies. Both wires are connected to the same amplifier output. Some report moderate improvement with this wiring.
To bi-wire the JBL L100 Classic 75, connect the speakers according to the following illustration.
Bi-Amplified Wiring
An amplifier and speaker system are bi-amplified when one channel of an amplifier is used for high frequencies, and one channel of an amplifier is used for low frequencies. One 2-way speaker could use both channels from a stereo amplifier. Selecting amplifier channels and wires better suited for different bandwidths can produce very noticeable improvement. To wire the JBL L100 Classic 75 for bi-amplification, connect the speakers according to the following illustration.
In either case, follow the instructions for the different connector types in Basic Single-Wire Connection, on page 4.
NOTE: For more information about various speaker-wire and connection options, contact your local JBL dealer.

CONTROLS/ADJUSTMENTS

JBL L100 Classic 75 Iconic 3 Way Bookshelf Loudspeaker - fig11

The L100 Classic 75 has front-panel adjustments that let you balance the levels of the midrange driver (MF) and 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 L100 Classic 75 it will take the drivers’ suspensions several weeks to “break-in” and achieve optimum performance. During this period, the balance between the woofer, midrange, and tweeter may change, so we recommend that you adjust the midrange and 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.

CARING FOR YOUR SPEAKERS

  • 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.
