About the JBL L100 Classic

JBL renews a best-selling classic

The original L100, introduced in 1970, is JBL's best-selling speaker of all time. They revisited that winning formula in the new L100 Classic, keeping the older speaker's classic 3-way design, and updating the drivers for a more lively, accurate soundstage.

The JBL L100 Classic boasts the same iconic 3-way design as its predecessor from the 1970s, with updated driver technology for a more dynamic sound.

JBL renews a best-selling classic

The original L100, introduced in 1970, is JBL's best-selling speaker of all time. They revisited that winning formula in the new L100 Classic, keeping the older speaker's classic 3-way design, and updating the drivers for a more lively, accurate soundstage.

The speaker still looks as great as it ever did, with a walnut cabinet and classic Quadrex foam grille that's sure to bring back memories for music-loving Baby Boomers. 

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.

Product Research


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.

What is the size and weight of the package for jbl l100?
[ Dominic  Dec 05, 2020 ]

Sorry don't have exact weight and dimensions at hand. But, I will add this, they are much bigger than you probably envision and they are heavy, guessing 60lbs each.. But, they do sound great. You will need space for them. They are not bookshelf.
[ JEFFREY  Dec 11, 2020 ]
who makes the JBL L100 Classic? JBL doesn't know about this
[ GCreamer  Jun 01, 2020 ]
1 answer
They're made by the high end JBL brand: JBL Synthesis. They also make the HDI series of high end JBL speakers. Not allowed to include links so just search for JBL Synthesis.

I'm wanting to replace a pair floorstanding tower speakers that I use for a 2 channel home theater, and a turntable. Would these work as a replacement for that, or are they best for music only?
[ Will  Mar 26, 2020 ]
1 answer
These would work great for any 2 channel system. They will do great with TV/Movies, but will truly shine with high quality stereo music.
[ Calvin  Apr 15, 2020 ]  Staff
Will these fit on my bookshelf?
[ Trevor  Mar 01, 2020 ]

These are miscategorized, I think. They're 25" floor standing speakers with 12" woofers. Sure you can put them on the shelf if your shelf is that large;)
[ Adam Anon  Jun 07, 2020 ]
They will do fine with anything you run through them. A short pair of floor stands are a good bet. They should have spikes on their bottoms to decouple low frequencies from your floor to your turntable shelf: you run a risk of introducing rumble into your tonearm otherwise. Also a good reason to play your vinyl with the dust cover off the turntable!
[ Kevin  Apr 28, 2020 ]
Back in 1977 I was in the Air Force and the guys in our dorm all had them. Since we were two to a room, they usually sat on top of dressers, as floor space was limited. They are probably more suited to short floor stands than bookshelves-unless you have some really sturdy Amish-crafted units. They would do in IKEA units in a moment. One hack we learned BTW: to reduce unwanted vibrations, rest the speakers on two checkers, preferably covered with a piece of felt at each corner at least one inch inward from the edges of the speaker. Works wonders!
[ Kevin  Apr 28, 2020 ]
They are 15-3/8"W x 25-1/16"H x 14-5/8"D and weigh 58.5 lbs. How big is your bookshelf?
[ Cosmo  Mar 16, 2020 ]  Staff
Are my L100s from 1977 still good? or have they degraded a lot over time?
[ Todd  Jan 24, 2020 ]

The odds are you probably should replace your drivers at this point. The surrounds dry and become stiff over time, and all your coils are way past their prime. Google is your friend, you can find decent replacements online. Another concern will be your crossover networks inside the speaker. They can be removed and rebuilt, or you can get an active crossover for your system and bi-wire the cabinet. Depends on your budget and speaker lust! Your cabinets will be great. If you have some word working skills, you can put new veneer on the to spruce them up some if the years have not been kind to them. The exteriors can also be refinished without a lot of trouble. If your covers are OK, great. If not, there is also grill cloth online to put over the frames. In 1977, we always played our music with the covers off; you could hear the difference. I did all this with my old AR-3a pair, and they live on to this day.... Good luck!
[ Kevin  Apr 28, 2020 ]
Good question Todd. If they have been well maintained they should still be OK. Do they sound OK? Do they look OK?
