(100 degrees for 108P, 90 degrees for 112P) and the throw distance to the audience listening plane. In general, the goal is to separate P Series enclosures so that the -6 dB coverage angle of one enclosure is aligned with the main 0 degree axis of the other enclosure (and vice versa) at the listening plane of the audience. -
Page 23: 108P Nearfield Monitoring
For nearfield monitoring, either FILL (free space conditions, for example, when the 108P is placed on a console bridge) or MONITOR (half space conditions, for example, when the 108P is wall- or soffit- mounted) presets should be selected. -
