General:

These were recently re-issued by JBL due to their popularity, but here's your chance to own the original.

These were restored in-house in order to get them looking and sounding great.  

This work included:

• Cleaned L-pads w/ Electrosolve and Faderlube.
• Crafted all-new wood grill surrounds out of walnut.
• Sanded and stained the cabinets.
• Replaced rotted foam on both midrange drivers.
• Tested both speakers, now working like new.

All drivers work flawlessly and the speakers sound amazing. I now see what all the fuss is about regarding the L100's. 

The L100 is a legendary and collectible speaker as it has an accurate yet laid back sound which does not tire over a long listening session. Far better than most fatiguing hyper-realistic modern speakers.

Not sure why anyone would spend $5k+ on a re-issue set where you can have the true original version for the same amount.

More from JBL:

When it was found that musicians, engineers and other discriminating professionals in increasing numbers were purchasing the JBL studio monitor for home use, JBL introduced the L100 - acoustically identical to the studio monitor, yet offering provocative styling appropriate to the home environment.

Truncated pyramids of the Quadrex 2 grille dramatize unique lineage and advanced engineering of the L100.

New methods of sculpting semi-rigid foam material gave JBL the freedom to explore texture, color and shape. This reticulated (open-pore) foam - substantially the same material used for quality microphone windscreens - has been proven to transmit sound as well as even the most acoustically transparent grille cloths.

The grille frame and loudspeaker system enclosure are finished in hand rubbed oiled walnut on all four sides and can be placed horizontally or vertically.

Testing Process:
Our speaker evaluation process starts with a visual inspection of all drivers. We are looking for damaged or deteriorating woofer surrounds, dented tweeter domes, and cone damage. We also inspect the speaker connection points for loose or broken connectors.

After the initial visual inspection we connect the speakers to a reference amplifier with our preferred test tracks. With the speakers placed with proper distance we listen to each driver to make sure that they are producing the intended frequencies with no signs of distortion or rattle.

During listening tests with test tracks we check for proper stereo imaging and bass response at various listening levels. If there are any audible signs of issues, the speakers are taken to the bench where we perform a frequency sweep to isolate the issue so that it can be resolved by component repair or replacement.

Our subwoofer evaluation process starts with a visual inspection of all drivers. We are looking for damaged or deteriorating woofer surrounds, cone damage, or rubbing voice coils. We also inspect the input connections for damage.

After the initial visual inspection we connect the sub at our bench and perform a sine wave sweep from about 200 Hz down to around 10 Hz. During this sweep we are listening for excessive rattle or other signs of improper function.

If the sweep passes we then increase the input level to evaluate how the woofer performs at high output levels. If the woofer has built-in crossover adjustments or multiple connection options these features are tested at this time.

We complete the subwoofer evaluation by feeding the unit with an audio signal in conjunction with our house music system to see how it responds to low frequency content in real world conditions while paired with a full range system.
