We have a paging system that was installed so there is a set of two standard ceiling speakers that were installed in a single hallway adjacent to the stage. I would like to take one and reinstall it in the choir room adjacent to it (normally used as a dressing room), take another and send it to the other room we tend to use as a dressing room, which is across another hallway, and chain a third speaker in the series so that there will be one speaker still in the hallway. The PA system has a 60-watt amp. I asked the previous SM about hooking up a third, and he said it wouldn't work hooking up a third. I forget why, but I have heard others say it would probably be okay. Like I said - these are your average round ceiling speakers. So, my question is A) can I chain a third speaker, and B) If I move one of the hallway speakers to across the hallway (about 50' or so of wire), would that affect the volume much? I wouldn't think, but it is a small amp. Thanks!
