Soundstage and image height, does it exist?

Sounds stage beyond the speakers width is mostly room reflections. Try taking the speakers outside and see how they sound. I would bet they sound pretty different. 

Speakers outside would be similar to being in a hemianechoic chamber.  Good for testing but not much fun for listening.  The room has a lot to do with the imaging.

… what I do know is that when Jim Winey decided to make Magnepan speakers 6' high, the listener was treated to a source that more closely mimicked the experience of being at a live concert.  The "sound stage" of a concert is the hall you listen to it in.  Most halls are designed to provide a quality listening experience that is as tall as the hall and as wide as the stage.

The actual radiation field and its overall size and height is by far the most influential factor with regard to perceived realism and immersiveness of sound staging, as I see it. Again: with speakers there’s no escaping physics, inconvenient they may be to many. 

I certainly do get height from my system, but then my front wall is ~16 feet high and the back wall is ~7-1/2 feet high, so there could be some reflection adding to it.

If you want to hear height, the best thing I find is to listen to "sharp" percussion. Xylophone. marimba, glock, wood blocks, etc. always seem to come out higher.

Then of course there is the actual height of the speakers that can replicate the height of the actual instruments they are reproducing. For example, when I listen to the Big Red Supers, drum kits/solos come out very realistic as to their height. The aux woofer at the bottom of the cabinet reproduces the slam of the kick drum, whereas the 604’s horns are placed at the level of cymbols.

I consider soundstage and imaging an important part in  stereo's ability to pull me into the music. I started a thread on the ASR forum asking the experts if there were measurements for that and another thread inquiring about resolution. In my reality, what separates the $1000 pair from the $10,000 pair are 'stage, imaging and resolution and guess what? NOPE no such measurements, so these things don't exist Period. 

Until they get off that pulpit i'll remain skeptical. Any decent pair of speakers should 'stage and image. read up a bit and learn about placement and have fun with it.
