going to the latter loudspeakers, so that the wavefronts from near and far loudspeakers arrive at the same time. Because of the Haas effect an additional 15 milliseconds can be added to the delay time of the loudspeakers nearer the audience, so that the stage's wavefront reaches them first, to focus the audience's attention on the stage rather than the local loudspeaker. The slightly later sound from delayed loudspeakers simply increases the perceived sound level without negatively affecting localization.
