JBL EON15 PA Speaker problem

Question edited for clarity and typos.
Question moved to model category JBL EON15-G2.

If there is a quick blow fuse in the power supply unit, you might be lucky, but doubling the voltage can take out everything, PSU, Mainboard components and even including the coils on the speakers. You would have to open it up and test, or return it under warranty.

Check for voice coil resistance. Should be around the stated impedance rating. Assuming it is ok, then move the cone carefully back and forth along the magnet, if any rubbing the coil has been damaged. A damaged coil is not repairable - you replace the driver.

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)

Yes the woofer and tweeter can be replaced but the woofer needs a recone kit to repair as the whole speaker cannot be replaced without replacing half of the speaker enclosure.... call JBL pro or a service center for help.

For some reason the soft on protection circuit has failed. it is not a simple fix and would require the amplifier module to be removed from the speaker to assess the damage.

the braided wires from the speaker connectors to the voice coil could be broken (from repetitive movement) or it could be the voice coil it self that could be cut open from a miss alignment of the cone (ware and tear), delicately push on the cone and feel if it rubs, a simple test is to check the IMPEDANCE of the speaker with a OHMMETER, if you have a reading (4,6,or 8 ohms) than the speaker is fine, check the rest of the wiring, if it reads OPEN than you need a new speaker...

Swap the speaker with the other one to prove the source is NOT the problem and then get the tweeter fixed.

Since the coil is attached to to cone, you are looking at replacing the whole 15" driver (speaker)
To get access to the screws that hold it in place, you'll need to remove the front bezel from the cabinet, then remove the screws around the speaker's rim.

For what it's worth, that driver isn't a subwoofer, it's just a 15" driver. JBL does make 15" and 18" subwoofer drivers, but they aren't the same speaker as what's in this EON. Hopefully that will help you when you're shopping for a replacement driver.

it can be the amp or the speaker itself. it has to be diagnosed by a service center.
if the amp is the problem, there can be board replacements or component level repair. if it is the 15" speaker, then it can be reconed with authentic genuine JBL parts returning it to brand new. [email protected]

you can probably by a generic type of motherboard from a shop like JAYCAR lookem up on the net ]
