Abstract
An audio reproduction system includes an arrangement of audio speakers of a first kind having a first degree of directivity in combination with at least one audio speaker of a second kind having a second degree of directivity. In order to create a virtual sound source at a desired distance to a listener's position, the second degree of directivity is substantially larger than the first degree of directivity.
