Our Verdict
TCL Alto 8+
Samsung HW-A450
The Samsung HW-A450 is a better soundbar than the TCL Alto 8+. The Samsung has a more neutral default sound profile, which some users may prefer, a better dynamics performance, and offers more sound enhancement features like a graphic EQ. However, the TCL has an HDMI ARC port.
