Vizio SB3621 – The Home Theatre Speaker With Amazing Sound Quality

The world is changing at a very fast pace. I mean earlier the sound bar and home theatres were really costly and you had to spend thousands for good quality speakers. But today you can get amazing sound quality for just a few hundreds of dollars. This is made possible by brands like Vizio and Elac. The latest soundbar of Vizio the SB3621 is one of the great home theatre speakers. It can be purchased for as low as $150, but you will be amazed to see its performance.

The SB3621 is so compact and sleek looking soundbar which can effortlessly fit in small spaces. It is a cute and affordable device with great bass and sound. It is one of the best soundbars for your home which comes which gives a tough fight to expensive speakers.

The Vizio SB3621 has a wireless subwoofer and Bluetooth support. There are no additional features, but that is absolutely fine considering its low price. Surely the Yamaha and the JBL bars are a lot better they will cost you a lot as well. So if you have a limited budget or you want something good at a low price, then the SB3621 is the best choice for you.

The build Quality

Vizio SB3621

Talking about the build quality, no one will be able to say that it is a low priced sound bar by looking at the build quality and design. It looks pretty expensive and durable. It is 36 inches long and the height is about 2 inch. A compact design and no use of plywood. I have even compared the build quality to the JBL, but in spite of being a cheap priced bar, the Vizio still look great.

At the top of the bar, there is five feather touch control button. It consists of a power button, the volume up and down button, etc. There is one remote as well for controlling those functions, but the buttons would be really helpful in case you forgot the remote.

Now talking about the wireless subwoofer, it is also of equally good quality. It is a black color box which comes equipped with a 5 inches woofer.


The device comes with two digital input ports. It includes a coaxial and an optical port. Then there is a 3.5 mm universal audio jack support and a USB for WAV playback.

Easy setup process

Setting up your new Vizio device is a fast and simple process. Just plug in the optical cable in the given slot and then fine-tune the volume and bass. That’s it you can now enjoy high-quality movies with great sound experience.


  • Good sound quality
  • Very low priced
  • Excellent build quality
  • Wireless Woofers and Bluetooth support


  • Not suitable for big rooms
  • Lack of features



Overall the bar is stable and it performs decently. An awesome sound bar at a really cheap price but not at all cheap in terms of looks. So for those who have a limited budget, I would strongly suggest you buy it.
