An example implementation involves a first playback device receiving audio content to be played back by the first playback device and a second playback device in synchrony. Such audio content may include a first and second stereo component. The first playback device determines a limiting result that indicates frequencies at which a playback volume of the second playback device is limited and determines a crossover frequency based on the indicated frequencies at which the playback volume of the second playback device is limited. The first playback device causes the second playback device to play a first portion of the second stereo component that is above the determined crossover frequency and plays (i) the first stereo component and (ii) a second portion of the second stereo component that is below the indicated frequency in synchrony with playback of the first portion by the second playback device.
