Anyone have trouble with these?I have a pair but one is popping when it gets pushed close to unity gain.I swapped speakers and I see now its something to do with the amp.
JBL JRX100 powered 18 sub

What amp do you have? Could be just that you need to get some contact spray for the electric connections. I've had issue with the volume knobs on the QSC 2450. Spray them and the noise goes away. Sorry you said powered subs. You still may need to do that. But make sure that's it before doing so. You don't want to damage anything.
If you swapped out drivers and still have the problem my first guess would be the internal crossover but before you mess with that check your cables there could be a short in one of them
LOL he says it's a powered sub. Voodoo, you swapped the speakers and the problem stayed with the same cab. You need to have the amp serviced or replaced....there's a problem with it.

Thanks for the reply.I kind of feel like its the crossover too.Was hoping it was something common where I could just fix it myself.When it pops it kind of sounds like its hitting full range.
Apparently others are having the same problem

I must not be able to spell anymore...my last post <should> read: "Crossover is built into amp module". My bad!

Do these things not have limiters built-in? They definitely shouldn't be over-extending like that. Even though you swapped out the woofer, the cables still stayed the same (as already mentioned) so swap those out before messing with the amp module to see if the problem goes away. If it is still there, then send the amp module back into an authorized JBL shop for repair. Only authorized repair centres have access to the schematics required to fix such a problem. Powered speaker manufacturers like to keep their schematics away from wandering eyes...
Steve, these are JBL entry level in their time. No limiting except your own good sense. It's way possible Voodoo overextended the sub.......and it doesn't take much with this series. I just hope he can get it repaired without having to bend over too far!
