Thanks to everyone who responded to this. I spoke to EV the other day and they confirmed what has been said here and what I suspected all along. I've ordered components to rebuild the x-overs to factory specs. The EV guy felt that the components have taken a beating in the horn circuit, and it would be a good idea to replace them. I think this problem will be taking care of itself soon. I found out that the repeat offender DJ has caused a little too much controversy at this club and might be on the way out. I've told the owner of the results of my research and informed him of the amount he spent on driver replacement in '07. He seemed to understand that there is no magic solution for this and respect for the gear is what will prevent future problems. Only time will tell. If he continues along this path, I'll have to tack on repair charges along with the cost of the hardware. Thanks again for all your input.
John
