How to define a listening area?
1 Define the height between the loudspeaker and the
floor.
2 What is the desired maximum SPL variation from
centre to the edge of the listening area?
3 Look, in the table below, in the column for the
specified height and in the row for the specified
maximum SPL variation.
4 At the intersection of the row and column the
diameter and the surface is given of the listening
area.
