Soundstage and image height, does it exist?

Third, I can recall listening to the astounding width and height of the sound field produced by the Harold Beveridge ESL (back in '78). 

Volume can play a big part in getting the illusion of height. At least in my room. Low volume keeps everything closer to the level of the tweeter/your ears. At a moderate increase in volume every thing seems to open up. Just don't overdrive your room - sounds like crap. FWIW.

´´ why are people so worried about what others think or say on certain topics and then have to get others opinions ? ´´

You must be a very interesting person to talk to.

I hope you behave differently with friends and life partner .

@maxwave 

why do i need to behave differently with friends or life partner ?

so because i ask a simply question of what does it matter what others on a site say , you have a problem with it ?

@riley804

The ´´tone ´´ of your post is slightly arrogant . That is the way I perceived  it.
