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.
A great example at 2:00:
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.
