Our Verdict
onn. 42" 5.1. 2. Dolby Atmos Soundbar
Vizio M Series M51ax-J6
The Vizio M Series M51ax-J6 is better than the onn. 42" 5.1. 2. Dolby Atmos Soundbar. They're both affordable 5.1.2 setups with Atmos support, but the Vizio soundbar's Atmos performance is better. The Vizio comes with discrete satellites for a better surround sound, too. More sound enhancement features are also available, and DTS support, which the onn. lacks.
