Our Verdict
Vizio M Series M21d-H8R
Vizio V Series V21x-J8
The Vizio V Series V21x-J8 is better than the Vizio M-Series M21d-H8R. The V Series comes with a dedicated sub that can reproduce a more extended low-bass. It also has a better soundstage performance, and far less compression when you play it at max volume. That said, the standalone M-Series is better suited if you don't have a lot of space in your room.
