<p>A speaker system comprises a first speaker (203) and a second speaker (205). A driving circuit receives an audio signal and comprises a first drive circuit (209) generating a first drive signal for the first speaker (203) in response to a first filtering of the audio signal with a first pass band. A second drive circuit (211) generates a second drive signal for the second speaker (205) in response to a second filtering having a second pass band which comprises a frequency band below the first pass band. A delay (213) delays the second drive signal relative to the first drive signal. The sound from the second speaker is directionally radiated with a directional radiation pattern having a notch towards the listening position (111). The system uses the precedence effect and non-direct low frequency audio radiation to ensure that directional cues are predominantly provided by the first speaker (203) which may be small and positioned remote from the second speaker (205).</p>
