Abstract: An adjustable mounting assembly includes (i) a housing with front and rear collars joined by a threaded engagement, the rear collar including teeth oriented toward the front collar, (ii) a front body part extending outwardly through an opening in the front collar, (iii) an intermediate body part coupled to the front body part, and (iv) a rear body part coupled to the intermediate body part, the rear body part including teeth oriented toward the rear collar, the mounting assembly adjustable such that (a) when the threaded engagement is tightened, the teeth of the rear body part are positioned in an interlocking engagement with the teeth of the rear collar, preventing rotation about a pitch axis of the mounting assembly, and (b) when the threaded engagement is loosened, the teeth of the rear body part are disengageable from the teeth of the rear collar, allowing rotation about the pitch axis.

Abstract: Embodiments disclosed herein include playback devices configured to operate in one or more playback configurations including configurations individual playback devices play back one or more corresponding channels of multichannel audio content. An audio parameter can be determined based on a distance between playback devices. In some examples, the audio parameter comprises a filter such as a low frequency filter that varies based on at least the distance between the playback devices. After the audio parameter is determined, the playback devices can play back audio content according to the determined audio parameter.
