2Thank you for purchasing the JBL ® L100 Classic 3-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 L100 Classic is a modern interpretation of the original L100. The new L100 Classic honors this storied legacy with its iconic 12-inch (300mm) 3-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 monitor-type footprint, the L100 Classic features advanced JBL transducers including the JW300PW-8 Pure Pulp cone woofer, the 105H-1 Polymer-coated Pure Pulp cone midrange, and the JT025TI1-4 Titanium tweeter. The L100 Classic retains all of the performance attributes that endeared the original L100 to listeners in the ‘70’s and ‘80s, such as exceptional dynamic range and contrast, clean and effortless high output, and precise high impact bass. The updated L100 Classic adds even greater detail resolution across the full bandwidth, lower distortion and more lifelike stereo imaging, particularly off-axis. The L100 Classic is sure to become a new legend among music lovers everywhere.PACKAGE CONTENTS • One L100 Classic loudspeaker • One Quadrex foam grille • One L100 Classic Owner’s Manual PLACEMENT AND POSITIONING CAUTION: The L100 Classic weighs 58.8 lb. (26.7 kg) each. Before placing the speaker on a shelf or platform, be sure that it is sturdy enough to support the speaker’s weight.Before deciding where to place your speakers, survey your room and think about placement, using the illustration below as a guide.• A void placing the speakers near power amplifiers, heat registers or other objects that generate large amounts of heat.• D o not place the speakers in very humid or dusty places.• D o not place the speakers in direct sunlight or where they will be exposed to other intense light.• F or 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.• T he speakers will produce the most accurate stereo soundstage when the angle between the listener and the speakers is between 40 and 60 degrees.• G enerally, 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.• T he speaker will yield the best stereo imaging when oriented vertically.• T he L100 Classic may be stand mounted with optional JBL metal stands (model JBL JS-120, sold separately) that angle the speaker upward. • I f 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.min 20 inches (50cm)6-8 feet (1.8-2.4m)40° – 60°Listening PositionCAUTION: 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 L100 Classic has color-coded connection terminals. The“+” terminal is red, while the “–” terminal is black. See the illustration on the right.The L100 Classic is designed so that a positive voltage at the “+” (red) terminalwill cause the speaker drivers to move outward (toward the room).We recommend using a high-quality speaker cable with polarity coding. The sideof 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 amplifieror 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.BASIC SINGLE-WIRE CONNECTIONConnect the amplifier to each speaker as shown inthe illustration on the right.IMPORTANT: Do not reverse polarities (i.e., “+”to “–” or “–” to “+”) when making connections.Doing so will cause poor stereo imaging anddiminished bass performance.The L100 Classic’s gold-plated speaker terminalscan accept a variety of wire connector types:bare wire, spade connectors, pin connectorsand banana connectors.USING BARE WIRE OR PIN CONNECTORS:IMPORTANT: Make sure that the (+) and (–) wires orpins do not touch each other or the other terminal.Touching cables can cause a short circuit that candamage your receiver or amplifier.USING SPADE CONNECTORS:IMPORTANT: Make sure the (+) and (–) spade connectorblades do not touch each other or the other terminal.Touching blades can cause a short circuit thatcan damage your receiver or amplifier.USING BANANA CONNECTORS:Negative (-)TerminalPositive (+)Terminal+-Receiver or Amplifier(one channel shown)SpeakerConnector Panel A.

T ighten Cap3L100 Classic Owner’s ManualCONTROLS/ADJUSTMENTSThe L100 Classic has front-panel adjustments that let you balancethe levels of the midrange driver (MF) and tweeter (HF) relative tothe woofer.You can use these controls to adjust the speaker’s sound accordingto your room’s acoustics, or your personal taste. The “0dB” defaultposition is a good place to start. Whatever sounds best to you inyour room is the right setting.As with most speakers, after you start playing the L100 Classic itwill take the drivers’ suspensions several weeks to “break in” andachieve optimum performance. During this period, the balancebetween the woofer, midrange, and tweeter may change, so werecommendthat 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• W ipe the cabinet with a clean, dry cloth to remove dust. Damp cloths or cleaning paper may dull the cabinet’s finish.• D o not use volatile liquids such as benzene, paint thinner, alcohol, etc., on the cabinet. Do not spray insecticide near the cabinet.• T o remove dust from the foam grille, use a vacuum cleaner set to low suction.• D o not wash the grille in water.• I f the surfaces of the woofer and midrange cones become dusty, you can carefully sweep them clean witha soft, dry calligraphy brush or paintbrush. Do not use a damp cloth.• N EVER touch anything to the tweeter dome.SPECIFICATIONSSystem Type3-way bookshelf loudspeakerWoofer 12-inch (300mm) Pure Pulp cone (JW300PW-8)Midrange 5-1/4 inch (130mm) Polymer-coated, Pure Pulp cone (105H-1) Tweeter 1-inch (25 mm) Titanium dome with soft surround (JT025TI1-4) Impedance 4 ohmsRecommended Amplifier Power25-200 Watts RMSSensitivity (2.83V/1m) 90dBFrequency Response 40Hz-40kHz (-6dB)Crossover Frequencies 450Hz, 3.5kHzControls Attenuators for MF and HF DriversConnector Type Five-way gold-plated Binding PostsFinish Genuine walnut veneer enclosure with Quadrex foam grille in a choice of Black, Burnt Orange or Dark BlueDimensions (H x W x D)25.06" H x 15.34" W x 14.625" D (636.6mm x 389.7mm x 371.5mm)Weight 58.5 lb (26.7 kg) each Tweeter ControlMidrange Control4。
