A method and apparatus for adjusting a cross-over frequency of a loudspeaker system. The loudspeaker system includes at least a first loudspeaker for frequencies below the cross-over frequency and a second loudspeaker for frequencies above the cross-over frequency. A level of the first loudspeaker is matched with the second loudspeaker using a first test signal and a room response is compensated in the loudspeaker system on the basis of the first test signal. The compensated room response is measured using a second test signal. A maximum frequency for the first loudspeaker and a minimum frequency for the second loudspeaker are determined. A cross-over frequency that results in a minimum cumulative total harmonic distortion energy at one or more sound pressure levels is searched between the minimum and maximum frequency.
