So I was digging around at work in an old storage room and stumbled upon some JBL 4430's. I don't have a big house or really any other gear. I'm reading through zonker92 posts and I know these will need a little love before they are ready for the living room. I'm pretty sure these were used in a PA system from 95 - who knows. I have some questions of where to start in testing and easy things to check/repair. I have a QSC RMX850 to power them with right now. Will that work? is it horrible? I don't have any preamp gear at the moment. I'm looking for something just to get started preamp wise, so I'll take any suggestions. Here are some photos of the speakers.
