Our Verdict
TCL Alto 7+
TCL Alto 3
The TCL Alto 7+ is a better soundbar than the TCL Alto 3. The Alto 7+ comes with a dedicated subwoofer, and it has a better build quality. Also, its sound profile is more neutral and balanced. However, both soundbars don't support Atmos, and they don't have a lot of sound enhancement features and physical inputs.
