Soundstage and image height, does it exist?

Are they correct?

whether or not they are correct is their opinion . . you have people that think the earth is flat , so what does that tell you ?

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

when you listen to your system, what do you hear / experience ?

i am definitely not an expert in this and never claimed to be.....but doesnt the room and the room treatments play a huge roll in the soundstage of a room ?

A narrow floor-to-ceiling line source like the Carver speaker will do this better than any speaker with multiple drivers of varying sizes (B&W, Focal, Magico, Wilson ... as examples).

The Pipe Dreams speaker comes to mind - a favorite of Harry Pearson! It too was a tall line source.

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.
