    VERY HAPPY WITH PURCHASE

    I purchased the Vizio M51ax-J6 specifically because I wanted a soundbar with 5.1 “Dolby Atmos” and dual stereo mode for YouTube music. My old soundbar would only play music from the front/center & sub speakers. This soundbar did the trick. I now get great sounding stereo music from all 5 speakers, and killer movie/tv surround sound. I also wanted a soundbar that could be mounted flush under my new Samsung QLED 60” tv. This worked with inexpensive L-shaped brackets I purchased from Amazon. Pretty much all other soundbars I looked at with Dolby Atmos specs have up-firing speakers which they do not recommended mounting under your tv as the sound could be obstructed. This soundbar does not have speakers on the top. The up-fires are in the front & sides, angled up I suppose. Who knows if I’m getting true Dolby Atmos, but I’m definitely hearing a new-to-me type of surround sound which is awesome. I tried a few different connection configs, and found this works the best: 4K Firestick into HMDI E-ARC on the soundbar, soundbar out to HMDI E-ARK on TV. All 3 devices are in sync and sound great!

    Dolby Atmos surround sound for under $400...YES!

    For my movie room this system rocks! I have a fairly large home theater room and my current set up works great. I have the sub and two satellite speakers in the back behind our upper row and the surround sound is phenomenal especially with any action movie. The highs produced by the Soundbar are very impressive as well. This system is paired to our 75" TCL 5-Series TV via the HDMI eARC connection. I also like how Vizio included a small but useful LCD screen on the remote so you can know what input you're selecting and the adjustment settings. I've read other reviews about the subwoofer not sounding good but that's not the case with mine. Matter of fact, I had to turn my level setting down a little due because it was really shaking the room. For the price you get Dolby Atmos and that's really hard to beat. I would highly recommend this system to anyone!

    Great for small bedroom!!

    So I bought this sound system for my small room. It sounds very nice and gives decent bass. I’m very picky with sound and i can definitely say for the price it’s not bad. Obviously it’s not super top of the line but it works. I wouldn’t use it in a living room or a big big room. And The bass is a little lower than I wanted it to be in certain places. And I noticed some frequencies will make a rumbling noise but for Netflix, or gaming, and YouTube in a small room it does the job! Definitely recommend for small bedrooms!
