Actually John, in this case, the 22 sounded like a column of sound. It was very unnatural. When someone is talking to me, I don't perceive the sound as originating from a small area of their face. It sounds "bigger" and more resonant than that. The 150 adequately imitates this effect. The 22 that we heard on the other hand sounded like a very narrow, vertical line source.
