Our Verdict

Sonos Arc

Samsung HW-B550

Since the Samsung HW-B550 comes with a subwoofer, it can reproduce more bass than the standalone Sonos Arc. That said, the Sonos shines in other regards. Its stereo soundstage is better, as is its surround sound performance. It can playback height content like Dolby Atmos, unlike the Samsung soundbar. You can always add a sub on to the Sonos to improve its bass performance, too.
