    Tremendous Sound

    I'd been waiting for this since it was debuted at CES and when it finally came out I picked it up. And I am SO happy that I bought it. The sound is fantastic, the whole setup took less than 30 minutes and it blew me away and exceeded expectations. The wireless subwoofer pumps out decent (adjustable bass) and the rear satellite speakers connect via ~40ft RCA cable to the sub. To test the sound I watched the Blu-ray of Season 2 of Game of Thrones and from the theme music delivering bass to the forest scenes delivering true surround sound from the rear speakers I am very satisfied. The sound bar itself is loud and clear, and its volume can be lowered by itself, as can the rear speakers and subwoofer. I did not use the the wall mount brackets that come with the package, I put the satellite speakers on stands and the sound bar on the tv stand.

    I spent several years of my life immersed in the world of high-end audio, enjoying speaker systems from Dahlquist, Infinity, Magneplanar, and ADS. Along with that would be electronics from the likes of Hafler, LUX, APT, SAE, and Audio Research. Years later, when I wanted to put together a very reasonably priced video system, this speaker system really tweaked me. It is a very nice, spacious sounding sound bar and a bluetooth 6" subwoofer. Plenty to provide decent audio for a 55" HD video system, right. But, this system incorporates 2 more speakers that run off the subwoofer to provide the spaciousness that a true 5.1 system gives. No speaker cables running across the floor, either. No worrying about crawling through the attic or in the crawl space to run your wires to these rear speakers. And a true 5.1 speaker system, to boot. Who could ask for more? I am extremely pleased with the sound of this system. It will even work very nicely in a pretty large room. Way to go, Vizio!

    Great Product but Some Flaws

    Customer review by LoyalPizzaFan

    I was extremely excited to finally get my hands on this system from Vizio. I did a good amount of research before deciding to purchase the Vizio S4251w-B4. I also had to wait a little while to purchase this unit because these things were in great demand the first few weeks or so. I have now tested the item for about 3 weeks and here is the breakdown: After removing everything from the box I was initially pleased by the look and feel of the sound bar , subwoofer and accompanying components. They were solidly built and did not look or feel cheap. It took me about 30 minutes to set up because I chose to mount the sound bar above my TV with some brackets I purchased off of amazon. This set up turned out to be a great choice and adds a nice look to my overall setup. Once the sound bar was mounted everything else was a breeze to set up. I powered everything up and I began to fiddle with the sound settings. I bought this system for my home office, which is 12 x 14 feet, so I figured it would be ideal for the size of the room. I basically went down the list adjusting each speaker and it took about 20 minutes to determine the best sound for my ears. I put the system through the gauntlet. I hooked my Apple TV (optic cable) and HD DVR cable box (Coaxial) up to the sound bar. I played all sorts of music like rap, rock, and R&B and it handled each type very well. I will say that the subwoofer wasn't able too handle the higher frequency of the bass in certain music. I could hear the details in the music and the voice clarity was on point. I also cranked it up and the sound quality did not diminish. The sound was not harsh like it would be in lesser products. I also watched Life of Pi (great movie) to test the movie experience and that's when the Vizio really came to life. The audio truly filled the room. I could hear all the sounds that we normally take for granted like falling rain, breaking glass, blowing wind, rustling in the bushes, and every click of a cocking gun. The sub also performed very well. It delivered a lively boom whenever it was called upon and it also shook the room. I was a little worried that I would be able to tell exactly where the bass was coming from, directionally, but it provided an experience like you would have at a movie theater. The vocal audio was also crystal clear. There were some bugs that were readily noticeable as well. The first thing I noticed was that when running audio through the optical cable, using the apple tv, the sound would sometimes cut out when I stopped and started a movie on itunes or tv show when watching netflix. In order to get the audio to return I had to power the system off or switch the input. This may be an issue with the system having to re-transmit the audio signal or something. Also, when I pause something I'm watching the audio doesn't immediately return. It slowly fades back in while the video continues. This may be an issue with select units because I've read other reviews and most don't mention these issues or they haven't experienced them yet. These flaws are things I can live with for now but I may return it for a replacement unit real soon, once i have time. I have 3 months to do so. Overall, i would recommend this product to a friend in spite of the bugs because it truly does perform very well for the price. Goo job Vizio!

    First things first, my ears are 75 years old so I am blessed to hear anything, not sure I should be telling anyone about how great this sound bar sounds. With that in mind, feel free to skip to the next review, however, I can still give you some useful info on the set up of this bar. In a word, 'simple', setup is a snap but the remote is a little more challenging, may take some time to familiarize the buttons and how to move around the menu, but still not difficult. Two problems, the sound levels and the LED display, both need a little work. The LED display is hard to see in a dark room which is how most people watch TV, but my eyes are the same age as my ears, this may not be a problem for you. The sound level is very difficult to get adjusted to, one click on the remote button and you go from a 'funeral' setting to a 'rock' concert setting, one click of the button on this remote is comparable to five clicks on your normal TV remotes. If you can adjust to these two mild inconveniences this is a great bar for the money, Sam

    Replaced Boze system after a long distance relocation. After reading reviews, decided to try this out before investing in another BOZE. The VIZIO 5.1 system has exceeded my expectations and is a keeper for sure. Outstanding performance especially for the price.

    Im really interested in the Vizio S4251W-B4. I believe the rear speakers are wired to the subwoofer and the subwoofer communicates wirelessly with the soundbar (which is perfectly fine with me). Does anyone have any additional information on whether the wireless communication between soundbar and subwoofer will introduce any wifi interference? Does anyone know if the wireless communication is indeed on the 2.4 GHz spectrum? Im concerned that the wireless communication between the soundbar and subwoofer will interfere with my router's wifi connection which I will use to stream to TV and Bluray player.

    • A. The sub-woofer is a bluetooth device, so it will not interfere with the 2.4 GHz spectrum.

    • A. Thank you for inquiring about our product. The soundbar uses a pairing function to link to only the Subwoofer, preventing wireless interference. Thanks and have a great day!

    • A. The sound system is on the 5ghz spectrum according to Vizio customer service. It does not cause any interference with my wifi. I've been using it daily for a few weeks with no issues.
