Correct there and for a church with no budget they can start to see what needs fixing so this will help the current problem because his room should not be far off, depending on size difference, materials.
Let's be careful as whether it is REW or Smaart, SysTune, EASERA, Paxis, etc., all of those simply give you is information, they do not tell you what needs fixing or how to fix it. It's a bit like a thermometer provides the temperature but does not say if that is warm or cold much less suggest what to do because of it.
Taking that analogy a step further, if you are hot and the thermometer says it is cold then you might question what it is saying and you really need to be able to do the same with audio and acoustical analysis systems, you need to be able to know when the information they present seems valid or not or you might end up wearing a swimsuit in the snow.
They have two speakers in the rear corners on 8 ohm connection with 200 to 250 feet of wire.
Speakers actually in rear corners (as compared to fill speakers covering rear corners) are typically a bad idea unless they are for effects or surround sound.
Trying to see if we can get the 70 v transformers and separate amp after time delay to run these correct time delivery and in the 70 v we will not loose as much on cable or frequency from the long run.
200' to 250' is not that long a distance but what may be more of an issue is if these are at the rear facing in/forward then how do you properly delay them? In effect their natural delay is the inverse of the natural delay from the mains up front. This often means they are virtually impossible to effectively delay.
