Constant Curvature WST systems presets
The factory presets dedicated to constant curvature WST line sources are optimized for medium throw applications.
In the following sections, tables describe the loudspeaker congurations and the factory presets for each system.
Discriminant acoustic properties of each loudspeaker conguration are given, such as -10 dB bandwidth or LF limit, or
frequency response contour.
