Our Verdict

TCL Alto 6+

Samsung HW-A650

The Samsung HW-A650 is better than the TCL Alto 6+. The Samsung is a better-built 3.1 setup with better soundstage and center channel performances. It offers more sound enhancement features, like a graphic EQ, and it has a Full HDMI In port. That said, the 2.1 TCL gets louder with slightly less compression at max volume.
