No power I thought my jbl eon 10G2 speaker had a power converter built in and plugged it into a 240 volt system in Greece. I'm sure I burned something. Is there a fuse that is easy to replace - can I do it myself ??

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.
The crossover caps may have failed, or the tweeters themselves burned out. Using a small 1.5 volt cell touched across the tweeter leads should produce a sound. If not- they are burned out.
The JBL EON 305's are 8 ohm speakers. The PMP5000 wi;; produce 400 Watts per side into a 4 ohm load (600 Watts peak). Into your 8 ohm speakers, the peak current will be halved while the voltage remains the same so you ACTUAL power per side is 200 Watts. It is hard to know how much you expect to get out of the amp. This power would fill a venue of at least 2000 sq ft. If you need more sound, try borrowing another 8 ohm speaker for each side and parallel them with the EON's as a test. That will double the power and add 3 Db more of sound. Your main slider should be around unity typically. This amp is a class D switching type (very efficient) and runs on +/- 70 volt rails. giving about 45 volts RMS output. At 4 ohms, this is just over 10 amps giving 450 Watts... at 8 ohms this is around 5 amps or 225 Watts.
Please read my tip on Fixya about the ground hazard of channel A when using 1/4 inch cables out of the PMP units... essentially the BARREL of the connector from channel "A" is the HOT,... NOT the tip of the PLUG. Ground the barrel IN ANY WAY AND YOU FRY CHANNEL "A" AMP !!!
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!!!
are they still under warranty? Worth checking into ... JBL has a good warranty program for this series and local authorized repair centers ... if you are under warranty you could have a fix for free in about a week ...

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.

the eon woofer is designed to fit the small frame of the inside cabinet. The EV woofers look too deep to fit but you can try. I do think that the built in amps were set to work with only the JBL woofers so there might be a signal problem using the built in amp. The eon face seems to have their own screws to hold the grill so if they aren't holding you can drop some cement to help hold the srews in place. The front does not allow removal of the woofer so it seems whatever you do should not effect anything.
If no warranty - remove amp and check sub to another amp to isolate speaker from internal amp. Either the amp blew a channel or subwoofer blew. JBL's are typically well built. Has this speaker often been pushed loud often?
