Hello Peter from Devon and welcome to the Shack!
Very interesting setup you got... a different style HTPC so to speak. Neato!
REW is full range... we generally use it here for subwoofers measurements and thus we use graphs axis limits set from 10hz/15hz to 200hz. I have used it on several occasions with my ECM8000 to measure full range.
It would take a lot for a question to be dumb here at the Shack... we might call them "simple" to some of the more knowledgeable, but we have a common understanding and realize not everyone knows everything and we all start out knowing nothing. Hope I said that right.
