Four elliptical midwoofers ensure faithful playback of mid-range frequencies and maximise low-end output. The far-field microphone array uses advanced beamforming and multi-channel echo cancellation for quick and accurate voice control. Three passive radiators enhance low frequencies for balanced, powerful sound. Use the Sonos app to adjust bass, treble and loudness.
