The Pros & Cons

The Pros. The VIZIO SB3851s support wireless music streaming which is definitely an added plus. It also supports DTS Digital surround sound encoding for high quality audio processing. The two rear satellite speakers that come with the VIZIO SB3851s are rear mountable which is an added plus. Setting up the SB3851s is also easy and relatively straightforward due to the wireless pairing between the sound bar and the subwoofer.

The Cons. The bass response from the subwoofer, while decent, is not the best that we have heard. The sound bar is only 38” long which may affect the level of sound dispersion that you normally get with a true 5.1 surround sound setup.

Setup and Design

The sound bar on the VIZIO is paired to the wireless subwoofer which reduces the amount of wiring that you need to use to set up the system – they combine to bring crystal clear booming sound to your home environment. The wireless subwoofer is connected to the rear satellite speakers which you can position around you to create rear sounding channels for an immersive listening experience. It also connects easily to your TV receiver and the sound bar works very well with the left, center and right channels pre-built inside the sound bar. The setup on the VIZIO is extremely intuitive and easy – connecting the VIZIO to the TV and placing the sound bar and subwoofer took a couple of minutes with the wireless pairing.

Sound Performance

The sound performance of the VIZIO is very good and provides great sound for watching TV with the sound bar placed right on the front. The sound feels clear with impactful bass that goes really deep; the subwoofer feels extremely powerful and will easily fill up a large room when deep low-end frequency response. The sound bar is able to produce very detailed stereo sound – you can actually hear details in the music that you might not have heard before, such as background conversations and the sound of debris flying all over after an explosion. Listening to music on the VIZIO was also quite a good experience and vocal performances sounded really crisp and clear, with very good music separation that distinguishes between subtle notes in the music. The subwoofer provides exceptionally good bass and can really make your entire room shake with an immersive low-end sonic boom. If you are looking for the best home theater system to watch TV and movies, the VIZIO is a really good choice.


The entire system comes with detailed instructions on how to set up the surround sound speakers and pair the subwoofer to the sound bar. Because the sound bar and the subwoofer connect wirelessly to a TV or Bluetooth source, the only wires that are required are for the satellite speakers. It also comes with a very convenient remote control which you can use to configure the volume controls and adjust the bass and treble outputs. The speakers have a very sleek and modern looking aesthetic appeal and blends in easily into your TV area.
