I ran my IIIas for over 10 years with the perpendiculars to the panels pointing directly at my ears. Then I did some experiments, as I found that the music got more engaging if I leant forward on the couch - so the ribbons were pointing behind my head.
So I made toe-in less - so the perpendiculars from the panels were crossing about 3' behind my head. Yes, that sounded better - but then I found that it still sounded better when I leant forwards - so I now have the ribbons pointing to about 7' behind my head.
According to Josh, this also helps the bass as it puts the bass panels more parallel to the front wall (parallel is best for a dipole). In my case with my 'Frankenpans', I can have the bass panels pretty much flat with the front wall and the ribbon/mid frames pointing 7' behind my head.
But, yes, your ears need to be at the half way point of the drivers (with the panels vertical).
