Ever since the first time I walked into a hi-fi shop and did my first speaker audition I noticed that there were some speakers which sounded more 3 dimensional or imaged better than others. I've heard salesman refer to this quality as a disappearing act, and furthermore the sign of an audiophile quality speaker was one where you couldn't tell where the sound was coming from. I'm sure someone here has an idea and probably knows what causes certain speakers to excel in this way. What is the scientific fact, and how does it differ from salesman fiction?
