AB  - Surround systems are typically based on fixed-directivity loudspeakers pointing towards the listener. Laitinen et al. showed for a variable-directivity loudspeaker that directivity control can be used to influence the distance impression of the reproduced sound. As we have shown in a listening experiment, using beam-controlling loudspeakers, stable auditory events at directions additional to the loudspeaker positions can be created by exciting specific wall reflections. We use these two effects to enable distance control and increase the number of effective surround directions in two different surround setups. We present IIR filter design derived from a physical model, which achieves low frequency beam-control for our novel cube-shaped 4-channel loudspeakers.
