Audio output balancing during synchronized playback

A method comprising:

• receiving, by a first playback device, audio content comprising a first audio signal and a second audio signal, wherein the first playback device is configured to play the first audio signal according to a first crossover frequency in synchrony with the playback of the second audio signal according to a second crossover frequency by a second playback device;
• determining, by the first playback device, a first limiting result that represents playback of a first audio signal by the first payback device by applying, to the first audio signal, a first pre-determined volume-limiting function that is associated with the first playback device;
• determining, by the first playback device, a second limiting result that represents playback of a second audio signal by a second payback device by applying, to the second audio signal, a second pre-determined volume-limiting function that is associated with the second playback device, wherein the second limiting result indicates frequencies at which a playback volume of the second playback device is limited;
• and
• determining a third crossover frequency based on the indicated frequencies at which the playback volume of the second playback device is limited, wherein the third crossover frequency is higher than the first crossover frequency, and wherein the first limiting result indicates that the first playback device is less limited at the frequencies at which the playback volume of the second playback device is limited;
• and
• configuring the first playback device to play the first audio signal according to the third crossover frequency.

A non-transitory computer-readable medium having stored thereon instructions executable by a first playback device to cause the first playback device to perform functions comprising:

• receiving a first audio signal, wherein the first playback device is configured to play the first audio signal according to a first crossover frequency;
• determining a first limiting result that represents playback of a second audio signal by a second playback device by applying, to the second audio signal, a pre-determined volume-limiting function that is associated with the second playback device, wherein the second playback device is configured to playback the second audio signal according to a second crossover frequency, and wherein the first limiting result indicates frequencies at which a playback volume of the second playback device is limited;
• determining a third crossover frequency based on the indicated frequencies at which the playback volume of the second playback device is limited, wherein the third crossover frequency is higher than the first crossover frequency;
• and
• configuring the first playback device to play the first audio signal according to the third crossover frequency.
