The problem of dividing the listener space of a commercial series-production car into several acoustical zones is examined. The sound of each zone is to be isolated from the sounds of the other zones and may consist of e.g. music or speech. A solution is proposed where the low frequency part of the problem is solved by the installed entertainment system speakers and the higher frequency part of the problem is solved by inexpensive local speakers. This paper focuses on the low frequency part of the problem and presents a solution that generates a sound pressure difference between all zones in excess of 10 dB for most frequencies in the range 70-400 Hz for an example problem.
