I've been the proud owner of 2 1st generation powered (bi amped) JBL Eon 15" monitors and they've endured enough to where I shouldn't question their longetivity but because I left them in a friends motorhome and it took some time and severe heming and hawing to get them back, I have to wonder...cuz they both sounded horrible when I finally plugged 'em in. Easy to realize that only the woofer was bumping, so the horns were gone. What bothers me is that both horns/amps would go out at exactly the same time, though I think my boy tried to bump the volume to insane levels by hitting the gain reserved for vocals and thus blew em at the same time. With what little I know about electronics, I took one apart and tried a mediocre bench test by hooking the pos/neg wires to a working speaker. I figured if the speaker worked, replace the horn, speaker don't work, one of the amps is shot and it's gonna cost a handsome Lincoln to fix'em. No sound;( Has this happened to anyone else? Is my bench test enough to convince you it's the amp.A lot of circuit boards inside look easy enough to replace if I could figure out which one to replace. An help appreciated.
