Sound Reproduction: Psychoacoustics of Loudspeakers and Rooms

What are the characteristics that determine the sound quality of an audio system? This is a question that for too long has been shrouded in mysticism as if there were some ephemeral magic that touched some systems and not others. But, the truth is this question can be approached objectively, and indeed that is what Dr. Floyd Toole has been doing with over a lifetime of scientific research. The results of his research is presented in a clear, concise third edition of his book 'Sound Reproduction,' which makes for an enlightening read for neophyte audio enthusiasts and long-time audiophiles alike.
