If one has "toed-in" speakers does the first reflection point shift towards the listening position? My presumption is that it does. Also, after identifying with the aid of a mirror the start and the end of the first reflection zone (when accommodating a seating area with lateral movement, i.e. left or right of the middle, the start defined by when one can begin to see the opposite speaker in the mirror and the finish when one can see the closer speaker in the mirror) is there any benefit, if one has a panel wider than this zone, of placing the panel such that the excess is biased towards the seating position (obviously ensuring that the reflection zone is covered)?
