The Polk Audio Signa S3 was rated 6.4, while the Sonos Arc has a rating 7. The soundbars are equipped with a different number of buttons, power, source, demo, volume down, volume up for the Signa S3 and volume down, volume up, play/pause, microphone for the Arc.

An external subwoofer can be connected to any of the units in this comparison. Rate 4 out of 10 received the Polk Audio Signa S3 for audio features and specs, but the Sonos Arc received 5 out of 10. Each of the competitors can play content from Spotify.

As in the Signa S3, so in the Arc there is the HDMI Audio Return Channel (ARC). We rated the connectivity of the Signa S3 at 5 out of 10, while the Arc was rated 7/10. Each of the soundbars can be controlled using the application. The soundbars in this review are equipped with a microphone. The models under consideration cannot become part of a multiroom system.
