Wide spacing will cause off axis irregularities (combing) because time offsets start to
become significant. See Section 4.10 for a more detailed explanation.
♦ An odd number of half wavelengths will cause nulls along the line of the
loudspeakers (the 90º lines) - see the 2½ wavelength example above
♦ An even number of half wavelengths will cause lobes along the line of the
loudspeakers - see the 2 wavelength example below
The following tables give the maximum recommended gap (between W8S sides) for
the relevant frequency range.
W8S' standing upright
Gap Smooth coverage range
0.5m 38 - 160Hz
1.0m 38 - 110Hz
2.0m 38 - 80Hz
To avoid mid-bass combing keep horizontal gaps below 500mm for upright W8S'
