1. A first playback device comprising:
- a network interface;
a processor; and
a tangible, non-transitory computer-readable medium comprising program instructions stored on the non-transitory computer-readable medium that, when executed by the processor, cause the first playback device to perform functions comprising;
while paired with a second playback device for playback of audio content, receiving an indication that an orientation of the first or the second playback device has changed;
based on receiving the indication that the orientation of the first or the second playback device has changed, caused a mobile controller device to display a selectable indication that, when selected, initiates calibration of the paired first and second playback devices;
based on receiving an indication that the selectable indication has been selected;
determining a crossover frequency of the first playback device and the second playback device;
after determining the crossover frequency, outputting, with the second playback device, at least a first tone set and a second tone set, wherein the first tone set is the same as the second tone set, wherein each of the first tone set and the second tone set comprises at least one fundamental frequency and at least one harmonic tone of the fundamental frequency, and wherein the first tone set is output in phase with the second playback device whereas the second tone set is not output in phase with the second playback device;
after outputting the first tone set and the second tone set, receiving, from the controller device, an indication of a selected one of the first tone set or the second tone set; and
adjusting a phase setting of the first playback device based at least in part on the received indication of the selected one of the first tone set or the second tone set.

Abstract
An indication of an acoustic characteristic of a playback device may comprise an orientation of the playback device with respect to an axis of a sensor of the playback device. After receiving the indication of the acoustic characteristic, a crossover frequency of the playback device may be determined and a series of tones may be output. A phase may be set based at least in part on a received indication of a selected tone set from the series of tones.

12. A method implemented by a first playback device, the method comprising:
-
while paired with a second playback device for playback of audio content, receiving an indication that an orientation of the first or the second playback device has changed; based on receiving the indication that the orientation of the first or the second playback device has changed, causing a mobile controller device to display a selectable indication that, when selected, initiates calibration of the paired first and second playback devices; based on receiving an indication that the selectable indication that has been selected; determining a crossover frequency of the first playback device and the second playback device; after determining the crossover frequency, outputting, with the second playback device, at least a first tone set and a second tone set, wherein the first tone set is the same as the second tone set, wherein each of the first tone set and the second tone set comprises at least one fundamental frequency and at least one harmonic tone of the fundamental frequency, and wherein the first tone set is output in phase with the second playback device whereas the second tone set is not output in phase with the second playback device; after outputting the first tone set and the second tone set, receiving, from the controller device, an indication of a selected one of the first tone set or the second tone set; and adjusting a phase setting of the first playback device based at least in part on the received indication of the selected one of the first tone set or the second tone set. - View Dependent Claims (13, 14, 15)

16. A non-transitory computer-readable medium having program instructions stored on the non-transitory computer-readable medium that, when executed by the processor, cause the first playback device to perform functions comprising:
-
while paired with a second playback device for playback of audio content, receiving an indication that an orientation of the first or the second playback device has changed; based on receiving the indication that the orientation of the first or the second playback device has changed, causing a mobile controller device to display a selectable indication that, when selected, initiates calibration of the paired first and second playback devices; based on receiving an indication that the selectable indication has been selected; determining a crossover frequency of the first playback device and the second playback device; after determining the crossover frequency, outputting, with the second playback device, at least a first tone set and a second tone set, wherein the first tone set is the same as the second tone set, wherein each of the first tone set and the second tone set comprises at least one fundamental frequency and at least one harmonic tone of the fundamental frequency, and wherein the first tone set is output in phase with the second playback device whereas the second tone set is not output in phase with the second playback device; after outputting the first tone set and the second tone set, receiving, from the controller device, an indication of a selected one of the first tone set or the second tone set; and adjusting a phase setting of the first playback device based at least in part on the received indication of the selected one of the first tone set or the second tone set. - View Dependent Claims (17)
