Abstract: Embodiments described herein involve a network media system identifying a primary zone in the network media system to play back audio tracks of videos. The system determines respective audio responses of one or more auxiliary zones and identifies a particular auxiliary zone for coordinated playback of auxiliary audio content based on the respective audio responses of the one or more auxiliary zones indicating that the particular auxiliary zone is within audible range of the primary zone and the particular auxiliary zone including a subwoofer. While an audio track of a given video is playing back, the network media system temporarily forms a playback configuration in which the primary zone plays back primary audio content including full frequency range audio content of the audio track and the at least one auxiliary zone plays back auxiliary audio content including low frequency range audio content of the audio track.

Abstract: Embodiments described herein involve selecting a coordinator device for multichannel playback by a first playback device and a second playback device are joined into a zone group of playback devices that are configured to render audio content from an audio source in synchrony. An example implementation may involve determining that a wireless interface performance metric of the first playback device exceeds a wireless interface performance metric of the second playback device. Based on such a determination, the first playback device and the second playback device may be configured as a group coordinator and a group member of the zone group, respectively. The group coordinator (a) receives the audio content from the audio source, and (b) forwards at least a portion of the received audio content to a group member during rendering of the audio content by the zone group of playback devices.
