Sonos Arc Features: All eleven Class-D digital amplifiers have been perfectly tuned to the soundbar's unique acoustic architecture. Three precisely angled silk-dome tweeters create crisp, high frequencies and crystal clear dialogue. Eight elliptical woofers ensure faithful playback of mid-range and vocal frequencies plus impressive bass. The far-field microphone array uses advanced beamforming and multi-channel echo cancellation for quick and accurate voice control. Use the Sonos app to adjust bass, treble, and loudness. This software measures the acoustics of the room then fine-tunes the soundbar. Supported iOS device required.
