What is it?: In an optimal listening environment, the soundstage is considered to be parallel to the floor, with origin point at the listeners head. This property specifies the vertical angle off of the soundstage plane giving up/down angle references as a location for a referenced element. Zero degree references are forward on the soundstage plane, with positive angular values being upward, and negative values being downward. This property only describes the desired end-user effect and does not specify how it is produced.
