AB  - It is possible to arrange loudspeakers in such a way that only one lobe emits from the array. This lobe can have an arbitrary beam width and to a certain extend an arbitrary beam shape. Because of this control over the beam, narrow beam widths can be made where wave fronts travel coherently 200 meters or more. It is possible now to cover an area below and in front of the array from almost zero to 200 meters with even direct-sound distribution of +/- 3 dB, where the frequency response is only dependant on the transducer used and the air absorption. This eliminates the coloration-effects due to side or grating lobes.
