Crosstalk Cancellation systems may be used to recreate Binaural Audio over loudspeakers by controlling the pressure exactly at the listener’s ears, acting as a pair of ‘virtual headphones’. However, previously working Crosstalk Cancellation systems have only been built for one or two listeners. This work extends the problem to a three-listener scenario, including the build of a custom trio of Crosstalk Cancellation loudspeaker arrays. Furthermore, a novel loudspeaker dependent regularization technique is developed. This method lets the user specify exactly how much each loudspeaker in turn will contribute to controlling the pressure at each of the listener’s ears. In this scenario, the technique is used to create a system more robust to listener head movements and misalignments of the loudspeakers.
