I am going to make this short. What does coherency mean?
Certainly if the sound is coming from a line the whole line
cannot be the same distance from the ears. Consequently, if
anything a line source is less coherent than typical cone
and dome populated systems.

And planar-magnetic speakers would have the same advantages
(as you indicate) as electrostatic jobs. Nope, I cannot see
any advantage of the latter over the former, and I cannot
see any advantage of either over good cone/dome systems.

I am rather short of time, myself, which is why I have cut
up this post and do not intend to respond any more. 

Of course, if you spent less time writing lengthy
commentaries here and tried to hunt up a copy of one of my
books you might actually discover that I do make some good
points in them.

Enjoy your work.
