just an FYI - In order to remove ambiguity, we occasionaly need to clarify “front” vs “back” when describing walls. This has been discussed on many threads, and there has been an overall consensus, which is shown below from one of many different threads on the subject.

The convention is that the front wall is the wall in front of you when you are sitting in your listening chair (the wall behind the speakers).
Another way is to think of the speakers as at the "front of the hall" as in a theater. The ’rear’ wall is the one behind all the seats ;--)
