1. A method for processing audio signals, comprising:

  • electroacoustically directionally transducing by a first directional loudspeaker unit positioned in front of a listening position a first audio signal which is a first surround channel to produce a first radiation pattern with a first primary axis along which the acoustic output is greatest and a first null axis along which the acoustic output is the least;

    electroacoustically directionally transducing by the directional loudspeaker unit a second audio signal which is a first non-surround channel to produce a second radiation pattern with a second primary axis along which the acoustic output is greatest and a second null axis along which the acoustic output is the least;

    providing a user with a capability of alternatively selecting a first combined radiation pattern in which the first primary axis and the second primary axis are in substantially the same direction or a second combined radiation pattern in which the first primary axis and the second primary axis are in different directions.
