Sound & Performance

Along with design, the most important part in a sound system or soundbar is the sound quality. VIZIO’s 38” 2.1 Sound Bar delivers up to 100 dB with less than one percent total harmonic distortion which is really outstanding. It utilizes both Dolby and DTS audio technologies to deliver a multi-channel audio for a most incredible sound quality and its powerful bass transforms movies, music, and TV into a great experience. The 2.1 Sound Bar System features powerful speakers paired with a wireless subwoofer, delivering a clear sound with crystal-clear audio quality. This combination brings an excellent home theater experience to your home. We found the audio performance satisfactory.
