JBL L112 paper Cone Repair

[Klaus1993]

Good Evening,

I am in the process of repairing and restoring a pair of JBL L112 speakers which i picked up for just 35€.



As you can see, they are pretty beat up, and horrible things have been done to the Woofers :/

Fortunately i have been lucky enough to pick up a pair of JBL 128H-1 for 400€




One of the Tweeters also seems to be defective, but I just bought a working pair.

The only things left to do is fixing the horrible cutouts for the Car-Subwoofers, the Paint-Job and fixing the tears in the Mid-Speakers.

Now to my initial Question - Sorry for Digressing

The Mid-speakers are torn in a few places. Is it okay to just fix these holes with a thin layer of speaker-glue and Paper? Or would a fix like this ruin the Sound of the speaker? Is reconing the only option? (Its a bit intimidating to DIY)
I am fairly new to speaker repairs and have only repaired Foam-surrounds so far, so I would apprtiate any advice





I plan on Using them in my Home Cinema as rear speakers - My fronts are JBL L150a

Your idea of a paper reinforcement glued over the tear will work just fine. It will be less noticeable if you put it on the back.
The dust caps are aluminum. You can pull them back out with tape or with a bent pin. New ones are also available.
The cones themselves can be dyed blacker with a water based dye, just don’t get them too wet in the process.

Thank you very much for your tips!

Gonna try it out next weekend.

Use tissue paper or something thin. You want to avoid adding mass to the cone as much as is practical.
I used an airbrush to reblacken my cones.
