  • Patent number: 9872118
    Abstract: A method for identifying the position of loudspeaker boxes in a loudspeaker box arrangement includes the operation of a first loudspeaker box in the loudspeaker box arrangement as an acoustic test signal generator. An acoustic test signal from the first loudspeaker box is received at other loudspeaker boxes in the loudspeaker box arrangement. A positional relationship between the signal-generating first loudspeaker box and at least one of the other loudspeaker boxes in the loudspeaker box arrangement is ascertained on the basis of the acoustic test signal received in the other loudspeaker boxes.
