About the JBL L100 Classic Black Edition

Limited edition update to a best-selling classic

This limited edition JBL L100 Classic boasts an iconic 3-way design, updated crossovers and drivers, plus a new gloss black finish.
Limited edition update to a best-selling classic
The original L100, introduced in 1970, is JBL's best-selling speaker of all time. The L100 Classic keeps the older speaker's classic 3-way design, and the classic Quadrex foam grille that's sure to bring back memories for music-loving Baby Boomers.
This 2023 limited edition version features a solid cabinet with a unique black gloss finish, along with updated crossovers and drivers that improve the speaker's lively, accurate soundstage.
Now, fair warning: this is not a small speaker, and a pair must have JBL's matching JS120 speaker stands for proper placement and an optimal listening experience. But the resulting sound is so worth it.
What's under the grille
The L100's drivers and how they're positioned in the cabinet are a big part of what gives this speaker its bold, exciting sound. A white, 12" pure pulp woofer provides plenty of bass, with the help of a front-firing port. A pair of attenuator knobs — one for high frequencies, one for mids — let you fine-tune the performance of the dedicated 5-1/4" midrange and 1" titanium dome tweeter.

Features
3-Way Driver Design: The JBL L100 Classic loudspeaker utilizes a 3-way driver configuration with a 1" titanium dome tweeter, 5.25" polymer-coated pure-pule cone midrange driver, and a 12" pure-pulp cone bass woofer. The L100 Classic Loudspeaker delivers room-filling, full-range sound with exceptional dynamic range and detail, clean and effortless high output, and precise deep bass with low distortion.
Controls & Adjustments: The L100 Classic 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 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 JBL recommends that you adjust the midrange and tweeter controls again after the break-in period.
Note: The front-panel control adjustments are located behind the Quadrex foam grille. There is also a protective plastic film on the front control panel label that needs to be removed.
Bass Reflex Enclosure: The JBL L100 Classic loudspeaker employs a bass reflex enclosure with a front-firing port for higher efficiency and bigger bass response. The enclosure is finished in walnut veneer and is available with a black, blue, or orange Quadrex foam grille.
Binding Post Terminals: The L100 Classic loudspeaker features gold-plated, binding-post speaker terminals that will accept a variety of connector types - including bare wire (up to 10AWG) spade-connectors, pin-connectors, and banana connectors (single only).
Mounting & Placement Options: The L100 Classic may be stand mounted with the optional JBL metal stand (JS-120, sold separately) that angle the speaker upward. If not using the optional stands with built-in angle, then JBL recommends you to position each speaker so that its tweeter is approximately at ear level. The L100 Classic weighs 58.5 lbs. Before placing the speaker on a shelf or platform, be sure that it is sturdy enough to support the speaker's weight.
- For best results, place the speakers 6' to 8' 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, JBL recommends that you place the speakers at least 20" away from the sidewalls.
Note: This speaker does not offer any bracket, keyhole, or threaded insert for wall-mounting.
