All that's really needed is a clean tone, turn them up so you can hear it and hit a single note and let it die out. As greiswig has posted You will hear the note start to distort or make a splatter, just as if it's overloading the input stage.
Agreed! I had been really pushing my monitors the last few weeks and I had not been doing any intense listing until last night at a bedroom volume. Once I turn up to a gig volume I cant hear it at all.
The only problem I have with this is what happens (if anything) down the road? I'm not worried as I have Sweet Water behind me for 2 years. I just don't want to be at a gig and have a complete failure.
They will be going back for the repair no matter how minor it might be! I just have to find the time to get it done
