Systems and method are provided herein for balancing of outputs from playback devices playing audio content in synchrony. In one embodiment, the balancing of outputs may involve receiving a first audio signal to be played by a first playback device according to a first crossover frequency, determining a limiting result by applying a limiting function associated with a second playback device to a second audio signal to be played by the second playback device according to a second crossover frequency, and based on the first limiting result, configuring the first playback device to play the first audio signal according to a third crossover frequency. In some cases, the first and second playback devices may be configured to play the first and second audio signals, respectively, in synchrony.
