In some respects i also gather it could be an argument for not using even two matched subs, as room acoustics will invaiably mean that one is loaded differently and as such could cause a drop in overall levels.

Not a drop in overall level – that will actually increase. What suffers is overall response. It’s tricky to explain. This comes up pretty often, so I think a visual is really needed. I’ve been meaning to do a graph to show what happens the past couple days, but haven’t managed to. Maybe tomorrow or this weekend. Stay tuned.
