Hello BR549, as televisions continue to have larger screens with thinner profiles and sleeker bezels, there is less room for large speakers. To help get the best audio quality out of your VIZIO televisions speakers, we’ve included settings like DTS Studio Sound to provide the highest performance possible, while maintaining the thin, sleek, bezel-less profile of your television. If you’d like any help adjusting your audio settings feel free to contact VIZIO support at 844-254-8087.  For top of the line audio performance, you may also look into purchasing a VIZIO Sound Bar, there are several models available with wireless subwoofers for enhanced bass, rear speakers for true surround sound, and our new line of Atmos Sound Bars.
