Amazing Sound!

I bought this a week ago - coming from a 10 year old sound bar with a wireless 12 inch bass to this i was skeptical at first - but not anymore. This little base and amazing soundbar will rattle the windows! Very surprised! Also very surprised at what a difference up firing speakers make to a movie experience! I'm very impressed Vizio!

The Home Theater Sound We Deserve!

[This review was collected as part of a promotion.] Let's face it; the last year has been difficult in more ways than one. Not the least of which is the closure of so many of our favorite hometown movie theaters. I for one always enjoyed piling the family into the car, and going to catch a flick on a Friday night (even if I did have to pay way too much for popcorn and candy). But now, that’s all a distant memory. Movies are delivered directly to streaming services these days. And with the prospect of theaters ever opening fully again seeming less likely by the day, people like me are left searching for alternatives. VIZIO provides a lot of great options in that regard, to help turn your living room or family room into a fully functioning home theater. Even though they have lots of great television options, sound quality should never be overlooked. That's where the VIZIO M-Series 5.1.2 Channel Sound Bar comes in. 4K movies have become all the rage, there is a certain level of immersion that only Dolby DTS surround sound can provide. One of the unique things about the design of the M512a-H6, is the up firing speakers. Much in the way interior decorators use light to illuminate an entire room with a single bulb (by bouncing it off nearby surfaces), VIZIO has designed the M512a-H6 in a similar fashion. The audio travels upwards, hitting your ceiling, and raining it down around you to envelop you in a bubble of pristine, crystal clear sound. The subwoofer provides the deep, low resonance that you would expect from a chair-churning theater experience. But my favorite speaker of the entire family is the center bar. I can't tell you how much I hate having to turn the volume up and down, when the dialogue is too low or the action sequences are too loud. The M512’s center bar provides a perfect balance, keeping the vocals exactly where they need to be while ensuring we don't miss a single action packed explosion. Finally, the wireless functionality is always an added bonus. I personally don't mind running wires around the walls, behind baseboards and under carpet if I need to. But the Bluetooth does make set up a real dream. Unboxing a new speaker system will no longer be a chore, as VIZIO has always been forward-thinking regarding their installation and keeping up with all of the wireless trends. I'm eager to see where they go from here, not just on this front, but with their entire line of home entertainment electronics. I can't wait for the next opportunity!

Above average

Quality sound most of the time. Bought the M series 5 channel and was disappointed that there is no easy way to add additional speakers. Love the option to turn up the dialog making it easy to amplify voices. High frequency tones in movies frequently crackle despite quality of input.

Hello Pnk7, sorry to hear that you're having crackling. Have you tried connecting the sound bar with a different cable? While it's possible that there's a problem with the sound bar, cords/cables with frayed ends can also cause audio crackling. If you'd like any assistance, you can reach out to our customer service team by visiting support.vizio.com and clicking on 'Contact Us'.

Easy setup, great value

[This review was collected as part of a promotion.] Very new and just setup, so still testing. First impression: Typical Vizio product, as advertised. East yo set up, overall very good sound quality, love the Atmos & DTS. I am really enjoying being able to stream my music from Alexa via bluetooth. Can't beat it for the money

impressive surround sound

[This review was collected as part of a promotion.] Surround sound is impressive when watching movies. Video games sound great. Love having the ability to have an echo dot hooked up 24/7 to play music without having to have TV on. Subwoofer is good but not as powerful as my old Vizio sound bar.

Hopefully optimistic

I've had this sound bar for a few weeks and so far I've really enjoyed it. It took a bit to get the settings worked out with my tv but after that the sound has been great. One concern is some knocking in the subwoofer with certain bass noises. It doesn't happen too often, I just hope nothing is faulty.

Great when it works!

Soundbar sounds really good (when it decides to go output sound). Sound coming in through HDMI in works most of the time, eARC will work half of the time. TV detects the soundbar, soundbar turns on, but no sound output half of the time; to fix it I have to turn off/on unplug/plug in multiple times and sometimes it will start working (and continue working for a while until it decides to stop working again).

Sounds quality is good except some glitch

Budget friendly and quality soundbar. Good surround sound effects (dolby, dolby atmos)and also dual sound mode is good for music and movies especially for dialog delivery. Surround speakers stopped working after 8 months and waiting for the replacement. hope sound glitch issue also won't be there on replacement unit
