What really makes a soundbar the best purchase is obviously the overall sound quality. You always want to have the best possible quality on the market, and with the Vizio sb3821-c6, we believe you get there, even if the price is well under $200 all the time. You have that crystal clear sound that will give you the sound richness you need. And the fact that you don’t have to worry about any issues that appear with this sound aside from some harmonic distortion here and there is nothing short of impressive every time.
Aside from that, they are also bringing in Dolby Digital decoding. We find that to be a must, especially on those soundbars that want to offer a premium value. And we believe that you get that here without worries. They also added DTS audio post-processing and DTS TruVolume. This kind of stuff can really be incredibly important, and we believe that it does a very good job with the experience itself. To make things even better, the processing speed is great, and there were no delays with the audio. As we mentioned earlier, the subwoofer will have a bit of delay at times, depending on the signal strength. The unit itself is fine, but your device’s signal strength will influence the audio quality if you want to use the subwoofer. Otherwise, it’s more than ok.
