John Marks in his column The Fifth Element in the June 2011 issue said, "First is the ability of the loudspeaker boxes to disappear in the sense of not being readily apparent as sound sources" about a speaker he reviewed called the Silent Speaker II.
My simple question is why? First, we know the Boston Symphony Orchestra is not in our room any more than Vladimir Feltsman is (unless we're friends). Second, when we listen to music outside of our homes, we certainly know where the music is coming from as a sound source, whether it be a stage or in a bar.
Just something that I have always heard that never made a lot of sense to me.
