Our Verdict

TCL Alto 5+

TCL Alto 8i

The TCL Alto 8i is a better soundbar than the TCL Alto 5+. The 8i has a better soundstage and supports Dolby Atmos content. Also, it has more physical inputs, including a Full HDMI In port that supports 4k passthrough. However, the 5+ comes with a dedicated sub and is better built.
