Our Verdict
onn. 42" 5.1. 2. Dolby Atmos Soundbar
LG SP9YA
The LG SP9YA is better than the onn. 42" 5.1. 2. Dolby Atmos Soundbar. They're both 5.1.2 setups with Atmos support, but the LG is more versatile. It's better-built with a better stereo soundstage. There are more sound enhancement features available, too, and DTS support. It also has a more neutral sound out-of-the-box compared to the onn.
