The Vizio SB2020n-G6 has an only okay stereo frequency response when on the Music preset. As it doesn’t come with a subwoofer, it lacks thump and rumble. Although it still manages to pack a punchy bass, it can sound compressed and slightly distorted, even if you’re listening to your favorite tunes at a lower volume. The treble is fairly dark, too, which makes your mixes lose detail and clarity. On the upside, the mid-range is pretty neutral.
