AB  - A new filter design method to synthesize the wave field of a given virtual source in a horizontal plane is presented. The reproduction of the wave field is performed by a novel 'multi-exciter' distributed mode loudspeaker, which contains a special array of transducers, attached on a single panel. Below the spatial aliasing frequency, the diffuse behaviour of the panel as well as the individual directional characteristics of the transducers are taken into account accurately. Above that corner frequency, a modified design procedure is proposed, which employs energy considerations and spatial averaging. A number of such modules can be cascaded to a system, which allows true spatial audio reproduction over a large listening area.
