    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.

    This system works so much better than my Sony surround sound system. My Sony system had a tuner,sub,center, rear,left&right front and rear, so that's 7 speakers plus a sub. I could never get the surround sound to sound good, to loud or to soft. This vizio sound bar sounds 100% better for half the price I paid for the sony. Set up is easy and the wireless sub and rear speakers connect easy and work perfectly. I'd recommend this to anyone. I have it connected to my vizio 60".

    Customer has been confirmed to have purchased the item from Walmart.

    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!

    My wife and I recently purchased this Vizio sound bar and we are amazed on how easy the set-up was and also how clear the sound is. The fact that the sound bar and subwoofer are wireless is equally great! The satellite speakers are connected to the subwoofer with a cord, but that can be easily concealed behind curtains. The bass from the subwoofer is outstanding! My wife and I started connecting the system after our kiddo went to bed and we were finished in a matter of minutes, its that easy! Both our jaws dropped when we first heard how this product sounds. We have a 55-in LED Vizio tv and they both compliment each other very well. After adjusting some of the initial sound settings, we can now just use the tv remote to control the sound bar, which is very convenient (just be sure to turn off your tv speakers from the menu). Vizio products continue to amaze us on how affordable and reliable they are. I would highly recommend spending the extra money to purchase this sound bar if you are shopping around.

    Customer has been confirmed to have purchased the item from Walmart.

    My Vizio sound bar system arrived early which was great. I watched the "how to" install video online and it was just as simple as it was advertised to set up. I plugged it in and it worked just like I expected. It took less then 15 minutes to un-box it and set it up. The sound is amazing and fills my entire space up with quality sound. The wireless sub and back speakers are perfect and I did not have to have cords running all over the floor. The wires for the two back speakers are long enough to reach where I need them. This is perfect for our living room and affordable. I shopped online at several different web sights including Amazon and this was by far the best value out there. I would recommend this system and already have used it while entertaining. I have received compliments from my guest without asking about what they thought. The blue tooth function works like a champ and one of my guest was able to show off the play list of a new artist so that everyone could hear them. Overall this is a great system for the money.

    The sound is awsome from this unit. The wireless woofer works great and allows you to place the back speakers anywhere.
