Vizio M51ax-J6

Big, punchy, exciting sound ; Dolby Atmos and DTS:X support with virtualized height effects ; eARC support ; Dedicated audio input for smart speakers

Height cues occasionally lack precision ; No Wi-Fi connectivity

Crisp, punchy, dynamic, and exciting: Those are some of the words I’ve used to describe Vizio’s latest soundbars, including the pricier M512a-H6 (which adds upfiring drivers to the mix), and the M51ax-J6 earns the same praise—well, up to a point.
