The Vizio V Series V51-H6 is a budget-friendly 5.1 setup released in 2020. It has a pretty neutral sound profile that's suitable for listening to many different types of audio content, and there's some extra boom in the bass. Thanks to its dedicated subwoofer, it can accurately reproduce the deep thump and rumble in the bass range, and its two satellite speakers help create a fairly immersive surround performance. However, it doesn't support Dolby Atmos content.
