• In loudspeaker-based 3D audio systems, there are some acoustic crosstalk cancellation methods to enlarge the sweet spot' around a fixed listener position. However, these methods have common defect that most of them can be applied only to the specific narrow frequency band. In this letter, we propose the more robust acoustic crosstalk cancellation method so that we can cancel the crosstalk signal in far wider frequency band and enlarge 'sweet spot.' For this goal, we apply a sum and difference filter to the conventional three loudspeaker-based 3D audio system.
