Our Verdict
Sonos Arc
TCL Alto 6+
The Sonos Arc is a much better soundbar than the TCL Alto 6+. The Sonos is a better-built 5.0.2 soundbar that supports Dolby Atmos content. It has better soundstage, center, and surround performances. There are also more sound enhancement features available, including room correction. Even though it doesn't come with a dedicated sub like the TCL, it can still reproduce a similar amount of low-bass.
