1. A first playback device comprising:
a network interface;
a processor;
a non-transitory computer-readable medium; and
program instructions stored on the non-transitory computer-readable medium that are executable by the processor such that the first playback device is configured to:
receive, from a media source, audio content for playback in synchrony with display of corresponding video content;
determine (i) a first channel of a first frequency spectrum for transmitting control information to each of a second playback device and a third playback device and (ii) a second channel of a second frequency spectrum for transmitting the audio content to each of the second playback device and the third playback device;
transmit, via the first channel of the first frequency spectrum, (i) first control information to the second playback device and (ii) second control information to the third playback device, wherein each of the first and second control information indicates that the second and third playback devices are to play back media content in synchrony as members of a bonded group;
transmit, via the second channel of the second frequency spectrum, (i) at least a first portion of the audio content to the second playback device, wherein the first portion of the audio content is to be played back by the second playback device, and (ii) at least a second portion of the audio content to the third playback device, wherein the second portion of the audio content is to be played back by the third playback device; and
cause the second playback device and the third playback device to play back, respectively, based on the first and second control information, the first portion of the audio content and the second portion of the audio content (i) in synchrony with each other and (ii) in synchrony with the display of the corresponding video content by a display device.
