Vizio M Series M512a-H6 vs Vizio SV510X-0806

The Vizio M Series M512a-H6 features an expanded feature set and two upfiring drivers, compared to the more budget-minded Vizio SV510X-0806. Both bars are compatible with popular audio formats, like Dolby Atmos, Dolby Digital, and DTS. However, the M Series offers improved performance when it comes to frequency response, soundstage, and dynamics, which is somewhat due to its larger sub and wider bar. It also features HDMI In and optical support, as well as 5.1 PCM playback, expanding its connectivity options. That said, the SV510X-0806's more compact size and superior surrounds performance make it a compelling option at a lower price point.
