Although I have done this many times before, I again put on a left right test 
track using RACE and two line source ESL speakers and I can rotate my head as 
much as my neck permits without detecting any noticeable shift in the 
localization of the voices at the extreme right and left.  With two speakers if 
I stand up so I can rotate even more then the localization begins to shift but 
not all that much.  But with both front and rear speakers engaged even this 
does not happen.  Compared to earphone listening, the stage stays put with 
normal head rotation using this loudspeaker binaural method and head tracking 
is not required.
 
In the concert hall or movie theater one does not rotate the head all that much 
so I fail to see the significance of a possible 2nd degree fault of XTC here.
 
The question now is why is RACE XTC so robust that this rotation effect is 
not clearly evident especially with four (curved in this case) speakers.  The 
answer has to be that the signal is the same at both ears despite appearances 
or that despite the differences present the brain still localizes normally.

Imagine a XTC system reproducing someone speaking at say 60
degrees left. If I turn my head towards the virtual speaker
I expect more or less the same signal in both ears. There's
no way to achieve that with one ear almost facing the speakers
and the other one turned away from them.
