Question about JBL EON 15-G2 Powered DJ Speaker With EQ Speaker

Tweeter not working on 15" EON G2

I bought some used G2s, everything works great except there are no highs from one of the speakers (woofer is fine). Does this mean the tweeter is blown? I see the part is $50-80 online, should I buy and replace or is there a better way to diagnose the problem? thanks

    I have the same problem, and tested it with my multimeter, and got a reading of 3.8 Ohms, so it looks like my tweeter is okay. What's the next step? Thanks...

    Thanks for the reply, I opened up the G2 and with my ohm meter set to 20 Ohm range it reads infinite so I image its blown. However using it now compared to the other G2 I noticed the overall performance is pretty muffled, it doesn't get nearly as loud and the red peak light blinks on the "bad" g2 even at low levels. The woofer looks fine and I don't see any burnt electronics inside the case. Could the bad tweeter be related or should I snop somewhere else? These units have very little time on them but maybe were abused before I got them, thanks for any tips!

    Okay similar problem sound wise (sub works tweeter doesn't). I took
    the tweeter apart and the 'cone' didn't look blown and I don't think it
    is cause it would output something, if at least muffled shrill. The
    next step was to take the Main Amp Board Assy off to look for lose
    connections. I found nothing (granted I'm not to sure what to look
    for). I guess my question is I want to try resoldering the power transistors to the PCB, are they the two big black 63v guys on the inside of the Main Amp Board? Thanks for all the info already guys!

    I too have no high end to recently acquired EON 15 G2. I checked the resistance across the tweeter, and it was infinity. So I assume I need to replace something in the tweeter. Do I need to replace the diaphragm, are the whole assembly?

    thanks

I had the same problem with no highs from my G2. I initally replaced the HF diaphram and powered it back up and it started smoking and burned out that HF diaphram.

I then found that I needed to replace the whole motherboard assembly as one of the HF chips on the motherboard had blown. Once I replaced the motherboard and the HF diaphram (again), the G2 was back in great working condition.

Wish I had tried ohm-ing out first before I blew the replacement HF diaphram.

So if you don't believe your HF diaphram is blown. I would investigate at the motherboard. I talked to a repair specialist where I ordered my replacement part and he said that those HF components go bad over time. As tough as the G2's are, over time they will need new parts, as the components begin to fail.

Because these speakers get thrown around alot, many people think they are non-destructible - and as such things tend to come loose. So, triple check everything. If something doesn't look right, re-attach it like WAVEFORM did. The larger capacitors that come loose on these models, so look at those as well.

I have the same problem and the same conditions.
The tweeter is good, 3.8 ohms.
Some points of solding (donuts), have bad aspect.
I resolder the power transistors to the PCB and I solve the problem.

You will need to open up the unit. The tweeter could be bad, there could be a bad connection (1 lead broken or fell off), or the crossover section could be defective.

Lets eliminate the tweet first. Try measuring across the two leads with an ohm meter. It should read about 3-5 ohms. If it reads infinity, the tweet is blown and you need a new one. If you get a reading, post it here and we'll move on to the next step.

My jbl eon 15 g2 smell like burnt and everything works but the big speaker


The voice coil in the big speaker could have been damaged if driven to loud. See if the burnt smell is strongest near the center of the big speaker. If the voice coil is fried, you may be able to still find a replacement as there is a part number for the voice coil (V/C Assy, EON-G2220-27005-00) and the cone (EONG2
Cone Repl. C2REON15P-2)

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!!!

There are two power supplies in there, one for the woofer and one for the tweeter.
You may have blown one of them.
Are you under warranty? If so definitely check the JBL website for a local authorized repair center ... they are local people, usually very nice and easy to deal with, and the warranty coverage is excellent.

Eon 15-g2 upper part of my jbl is getting hot


The tweeter is not the problem. The Eons use the vents below the tweeter to cool the amp and woofer. Sounds to me like you have a power supply problem in the amp, possibly a bad capacitor or diode. You have to check the amp for proper operation.

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.
