1. A method comprising:

  • receiving a first lifetime estimate for a first type of acoustic component included in a first set of playback devices that are each configured to play back audio content with first signal processing settings that govern a manner in which each of the first set of playback devices outputs audio,wherein the first lifetime estimate is determined by mechanically stressing the first type of acoustic component of each of the first set of playback devices by operating each of the first set of playback devices at a predetermined volume;

    after a second playback device having a given acoustic component of a second type has been configured to play back audio content with second signal processing settings that govern a manner in which the second playback device outputs audio, receiving one or more statistics associated with movement of the given acoustic component of the second type that occurred while the second playback device played back the audio content with the second signal processing settings;

    determining a second lifetime estimate for the given acoustic component of the second type based on the one or more statistics associated with the movement of the given acoustic component of the second type and the first lifetime estimate;

    determining that the second signal processing settings will increase a lifetime of the given acoustic component of the second type by determining that the second lifetime estimate is greater than the first lifetime estimate; and

    based at least on the determining that the second lifetime estimate is greater than the first lifetime estimate, sending the second signal processing settings to a third playback device to configure the third playback device to play back audio with the second signal processing settings.
