Sounds like bad power supply capacitors

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.

you want JBL Professional group if this involves the Eon product line.

please use a different connectors and try if it works

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.

my son and i fixed an eon a decade ago that had this problem. we swept a sine wave through the audio spectrum and discovered it started barking somewhere around a low D on the piano.
Turns out the mains connection was intermittent right where it enters the eon from the wall. Soldered the ac power connections and the problem went away.
