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