1. A first playback device comprising:
a first spectrum radio for communication via a first wireless spectrum;
a second spectrum radio for communication via a second wireless spectrum;
at least one processor;
a non-transitory computer-readable medium; and
program instructions stored on the non-transitory computer-readable medium that are executable by the at least one processor such that the first playback device is configured to:
operate in a first mode in which (i) the first spectrum radio is enabled and the second spectrum radio is disabled and (ii) the first playback device receives, from a control device, audio content for playback;
receive a command to begin operating in a second mode in which the first playback device is grouped with a second playback device for synchronous playback of the audio content received from the control device; and
based on the command to begin operating in the second mode:
enable the second spectrum radio for communication over the second wireless spectrum;
cause the second playback device to enable a respective second spectrum radio of the second playback device for communication over the second wireless spectrum; and
coordinate with the second playback device for synchronous playback of the audio content using the second spectrum radio.
