AB  - The theory of analytical approaches for sound field synthesis like wave field synthesis, nearfield compensated higher order Ambisonics, and the spectral division method requires continuous distributions of secondary sources. In practice discrete loudspeakers are employed and the synthesized sound field is corrupted by a number of artifacts due to this discretization. This paper presents a theoretical investigation of the properties of the loudspeakers which are required in order to suppress such spatial aliasing artifacts. It is shown that the employment of such loudspeakers is not desired since the suppression of spatial aliasing comes by the cost of an essential restriction of the reproducible spatial information when practical loudspeaker spacings are assumed.
