Our Verdict
Samsung HW-Q70R
TCL Alto 8+
The Samsung HW-Q70R is a better overall soundbar than the TCL Alto 8+. Unlike the 2.1 TCL, the 3.1.2 Samsung supports Atmos content and has a discrete center channel that performs better than the TCL. The Samsung's default sound profile is a bit more neutral and has a more extended bass than the TCL. The Samsung can also get louder, and it has less compression at max volume. That said, unlike the Samsung, the TCL comes with an auto volume feature and a built-in Amazon Fire TV 4k media streamer.
