To prevent any speaker fading artefacts: how about placing a speaker on a rail behind a curtain, and then just move the speaker. Obviously, the challenge there is to make the mechanism that moves the speaker silent enough that the listener doesn't pick up e.g. on squeaky wheels ;) Another thing that might be worth testing: placing the listener's body in some sort of stiff suit or bucket that only reveals the head, and then repeating it with the listener wearing light clothing. The issue here: how much of low frequency localization is done with the ears, and how much by feeling the impact of pressure waves on the body. Particularly at concert-level volume, I think once can feel from what side the bass "hits" the body...
