I was recently put in charge of completely redoing the sound system at my church. I've redone systems before just no by myself. First of all any overall tips? Second i'm going to be replacing the speakers but the new placement is a problem so where? I'll try to get pictures of the place. I've had good experiences with JBL so that's what i've been focusing on, more particularly the JBL Eon305 or Eon315. Any experience with them?
