The Vizio SB46514-F6 has sub-par sound enhancement features. It lacks a room correction feature that would help customize the audio reproduction to your room, which means it might sound differently depending on your room. Also, it lacks a dialogue enhancement feature to make voices clearer, but at least there’s a night-mode that helps to level out all content’s volume. It also has EQ presets and individual bass and treble adjustment for you to play around a bit to find your preferred settings. Just like the SB36512-F6, you can either turn the height speakers on/off or use the Virtual setting, which creates a virtual height speaker effect using the front-firing speakers, according to the manufacturer.
