A method for determining the polarity of a loudspeaker including measuring a loudspeaker-room acoustical response at a position with a microphone and filtering the loudspeaker-room acoustical response for increasing the signal to noise ratio of a first peak corresponding to direct sound in the loudspeaker-room acoustical response, wherein the sign of a sample in the first peak in the filtered loudspeaker-room acoustical response indicates the polarity of the loudspeaker.
