Our take on the Vizio 5.1.2-Channel M512A-H6 Premium Sound Bar w/ Wireless Subwoofer

The Vizio M512A-H6 is a 5.1.2-channel sound bar system with a wireless subwoofer and two up-firing drivers that bounce height effects off the ceiling for Dolby Atmos. It adds two rear satellite speakers for true surround, and they can be wall-mounted along with the bar. It supports Bluetooth, Wi-Fi, Chromecast built-in, and voice control through Google Assistant and Amazon Alexa. It suits people who want real rear-channel and height effects without a receiver and separate speakers, and it competes with other Atmos bars that often cost more for the same channel count.
