You will need to determine if it's the amplifiers or the tweeter themselves that are not working. If you open up the cabinets and check each tweeter with an ohm meter for continuity it will show if the tweeters are working, in which case the amp is the problem. if the meter shows that the tweeters are blown, you should still hook up another tweeter or speaker to the horn amp to see if it's blown and therefor took out the tweeters.
If any of this sounds complicated, you'd be best off taking the cabinets to the repair shop.
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.
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!!!
First, unplug the stereo speaker then open the back. you see the 2 wires attached to the woofer then test it by multi tester. if it moved it means its okay. check the wires for the loosen speakers. solder it and test it.
problem could be in wiring, fuse, crossover or the components can be damaged. the original JBL tweeter and 5.25" speaker are no longer available so replacement options would be the only alternative. [email protected]
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.
