  • The subwoofer has a hard time at louder volumes


The very first thing you will see concerning Vizio’s soundbar is how glossy it seems. The soundbar includes a shallow profile, sitting just 2.1 inches tall, so low enough to sit under most TVs’ display.

It is coated on the front and leading to a great black cloth, with silver vinyl caps on the ends, giving it a subdued, minimalist appearance.


The electricity, Bluetooth, enter, and volume buttons on the surface are coated in the net cloth, making them look almost like touch buttons, even though they have concrete media.

The straightforward layout extends straight to the white LED lights, which operate vertically over this pub’s left side. They behave as volume signs, light up as the quantity rises, and aid when you control every setting, from bass to treble, into the energy of their surround speakers.

They will also flash in different configurations to describe problems, which may be confusing until you bust open the 48-page guide to reading about what every pattern means.

A similarly-styled silver and black subwoofer and sits on a foot tall. It syncs with the soundbar, letting you put it alongside your sofa or seat (optimally).

You will want to maintain it, too, because both 5.5-inch-tall satellite speakers aren’t wireless. They plug directly into the subwoofer using two quite lengthy strings that need to be long enough for many sized chambers.

I put them on little tables on both sides of me, but you might choose to invest in specific racks (attempt these Sanus racks ) or wall mounts, based on the room’s design.

Keep them pretty near your sofa, but slightly behind you, so that you may find the most from the surround effects.

Vizio soundbar setup includes little feet for its soundbar and quite a few helpful cables, such as a 3.5millimeter audio cable, 5-foot HDMI to get ARC relations (on newer TVs), 5-foot optical cable, RCA coaxial wires, and even a couple of Velcro ties so that you may keep your cable clutter to a minimal (how considerate!).

Bright Accessories

Vizio smartcast 36″ 5.1 wireless soundbar system – sb3651 gets the definitive collection of accessories I have seen in a soundbar, such as just about every cable you will want: HDMI, Toslink optical, RCA analog, 3.5mm-to-3.5mm for both cellular devices, and 3.5mm-to-RCA phono are included.

You get little pre-cut Velcro straps that will assist you in cleaning up your cables after installation.

Most producers provide identical power cords for the subwoofer and soundbar. Not so here. You get two power cords of different lengths: 1 is 103 inches, and another is 63 inches.

That is smart. You are more likely to have an electrical outlet close to the soundbar compared to the subwoofer, which means that you won’t need to be concerned about attaining a socket for the subfloor, and you’re going to have less cable to spiral up supporting the soundbar.

Control And Casting Concerns

I have a love/hate connection with the Vizio speaker comprised infrared (IR) remote. It is far better than the dinky remotes that come with many speaker systems and even has a tiny LCD, but it did frustrate me from time to time.

The LCD is nearly large enough to mention one brief term, permitting you to know which input you have chosen (ex: Bluetooth or optical ). Still, it isn’t easy to understand precisely how to switch between menus.

Finally, I figured out I needed to press down and up on the directional pad on the remote to change and left and into flip settings off and on, but not before breaking open that guide.

I am not sure how I did this, but I inadvertently set the whole speaker into demonstration mode at the same stage, which meant it would not listen to some controls or turn away. I thought it had been busted. Luckily, the guide has instructions for turning off that, too.

There is a learning curve, but you can change a good deal of alternatives when you do get the hang of it. Regrettably, not quite all of them.

To get the maximum from this speaker, you will also need to download the Vizio 36 5.1 SmartCast program for iPhone or Android. It will permit you to enable Chromecast and command the soundbar out of your cell phone.

Chromecast is a great bonus, much like it’s about Vizio’s E Series TV (that we give our WIRED Recommends badge). Still, it took me the better part of a day to get it to stream anything around Spotify, Pandora, or even Pocket Casts.

Finally, I did get it working, but each other Chromecast or Google Home apparatus has only worked. At least one other reviewer had similar problems.

Others suggest it functions fine. Fortunately, Bluetooth pairing is straightforward enough, and that means you’re able to join and play music which a manner without hassle.

Toot, Whistle, Plunk, and Boom

For the price tag, Vizio’s combination of the soundbar, subwoofer, and surround satellite speakers perform a killer job of immersing you in whatever film or Netflix show you are streaming. Its strengths could be instantly heard in a film like Star Wars:

The Last Jedi. The picture’s intro includes a giant struggle between Resistance bombers and a First Order Juggernaut Star Destroyer.

With encircle turned, I could hear bands of TIE Fighters whir around me as the conflict unfolded, and because everybody is in a hurry in Star Wars, characters frequently talk from behind the camera too.

Hearing voices and blasts go out of the front to rear can make a picture feel much more immersive than a few theatres.

The soundbar itself sets out tight hands, but it will seem somewhat boxed in and tinny once you crank the volume. High notes come through clearly, but low mids seem a bit washed out, and there is virtually nothing.

Luckily, the sub-balances items out well. Again, keep that sucker near, though. It is not strong enough that you feel the joys of an X-Wing engine shooting from throughout the room. The same holds for the rear satellite speakers, which did have any audible hissing at more significant amounts.

Music sounded clear but maybe not quite as hot as a speaker created primarily for songs. I had to turn off a bizarre setting named TrueVolume, which is assumed to level the quantity, but stopped up inducing tunes to play loud, then soft, then loudly in a disorderly way.

Despite all the set-off, I discovered it on a Few Spotify tracks, such as Attempt to Make It by Sloan. The Walking Dead episode also got soft and loud when I snapped it on PS4 (not Xbox One( strangely ), although other displays seemed nice.


Both digital and analog inputs and relations make this Vizio soundbar compatible with most devices. Everything you will need to connect the unit for your TV can also be contained in the box to generate setup even more straightforward and hassle-free.

It’s the HDMI cable to the HDMI ARC link Too. Compared to other cable choices like analog and optical, you can get your soundbar and TV linked in moments with HDMI.

Surround Sound

This Vizio sb3651-e6 36″ 5.1 channel smart cast soundbar system is a sophisticated apparatus that simulates virtual surround sound, together with the soundbar itself left, right and center channels.

You may have to tone down it a little with the degree of electricity it could produce, but the authentic surround sound experience is evident and up to the mark.

But, loud audio is nothing if you can not make out the address and sound details. Luckily, the SB3651-E6 soundbar has that too.

Together with proper pruning, the layout itself reveals this top-notch apparatus is capable of clear sound and outstanding functionality when paired with TVs.

5 Channels

The audio bar is configured to mimic 5.1 surround audio [1], the industry benchmark for expansive sound. But, what exactly do all these numbers mean?

Five stations mean that there are five noise-canceling factors from the audio bar left, right, middle, one subwoofer, and two back speakers. With those operating together, it offers you the home-theater audio which you want.

Cheaper products have two or three stations, plus they provide adequate sound quality. Therefore, the 5.1 channels of this vizio sb3651-e6 36″ 5.1 channel smartcast soundbar system or the 5.1 complete range speakers such as Onkyo HT-S3900 provide much more detail and clarity in the sound.


Cost is one thing we seem at before we purchase products, and considering the features of this soundbar, it is a bit more expensive than entry-level Vizio versions.

On the other hand, this soundbar’s purchase price is also quite reasonable considering the simplicity it provides Vizio Smartcast and the superb sound quality. And due to the audio choices, this soundbar is used for rooms of any size, whether large or small.

All in all, the audio is relatively near Atmos versions, which ought to be sufficient for many surround audio lovers. Considering our entire inspection, this is a great purchase, and the cost for this particular top-notch Vizio soundbar is merely perfect.


As a 5.1 channel soundbar with sub and rear speakers, the Sb3651-E6 provides exceptional sound for a minimal price. Additionally, it offers all of the most delicate features a consumer would have to make the ideal home theater surround sound.

Using its compatibility with Chromecast, Apple Airplay, Google Home, and other solutions, this audio system provides convenience jointly with immersive audio quality. In the Long Run, it’s easy to see that the machine is worth the Purchase Price.
