Troubled JBL EON 15

My powered JBL EON 15" (old original model) has issues. It begins distorting at some very specific frequencies after running for a couple hours. One song will distort, and the next might not. If i turn it off for a while, then back on, it will not have the problem for a while, then start doing it again. I just had the tweeter replaced recently so i don't think that is it. I opened it up and looked for loose connections and there was a ground wire that seemed a bit loose, so i tightened that up, but apparently that wasn't it either. Since it seems to be frequency specific i thought maybe a bad crossover. But since it only happens after a period of use, it seems logical that something is heating up - presumably the amp(s) or crossover (can it heat up?). Any ideas? I'm tired of spending a couple hundred bucks each time i take these things into the shop.

Yes the crossover.. if you look at it you will notice a few coils and heat sinks,, the thermal grease may have come on done not to allow sufficent cooling,, eighter unsolder and add back thermal grease or replace it..

I installed a brand new tweeter in my JBL EON 15 G2 & the new tweeter blew. What else could be the problem?


These are "powered" speakers and any little bit
of distortion can be amplified enough to "blow" it!
Also the amp could be "shorted"! Have your JBL
dealer test it!!!

JBL Eon G2 Speaker


from our experience rebuilding woofers once the lead wires get pulled too much or start to strain you have been running too much power into the woofer and making the cone move too far in and out.You need to cut the input signal from your preamp down and cut the volume down on the speaker input on you eon. We keep seeing too many of these amped speakers blown from too much signal.

Jbl distortion! frame warped?


Nope. WE have about 50 of these with no problems. Please describe the type of distortion that you have. It may be as simple as a bad transistor in the power amp.

JBL EON 15 G2 clicks and pops


my son and i fixed an eon a decade ago that had this problem. we swept a sine wave through the audio spectrum and discovered it started barking somewhere around a low D on the piano.
Turns out the mains connection was intermittent right where it enters the eon from the wall. Soldered the ac power connections and the problem went away.
