Summary: 
This paper proposes a method for controlling multi areas by loudspeakers smaller than the number of control points. In this method, crosstalk components are suppressed by switching control points at each frequency band. As a result of numerical simulation, we can achieve suppressing the crosstalk components by about 3 dB.
