Our Verdict
Vizio V Series V51-H6
Sonos Beam (Gen 2)
The Vizio V Series V51-H6 and the Sonos Beam (Gen 2) are two very different soundbars. The Vizio is a 5.1 setup with a dedicated sub and satellites included. It can reproduce a more extended low-bass and get louder than the Sonos. However, some users may prefer the Sonos' small, standalone design. The Sonos is better built, and unlike the Vizio, it supports Atmos content. It also has a better soundstage despite its smaller size.
