This ‘rule’ doesn’t always hold true. The proof is in a recent trend in the soundbar market: The economy product line that packs a powerful punch.

In the quest to create the best budget sound bar, companies like Pioneer and Elac have soundbars that render excellent sound for an attractive price. So does Vizio, which has a product line of entry-level soundbars: The SB3621n-E8. We review this 36-inch, 2.1 channel soundbar to find out if Vizio succeeds in striking the balance between pricing and performance.

Design: Soundbar

The design people at Vizio went for an understated aesthetic that allows the SB3621n to disappear into your entertainment setup. At only 2.1 inches high, this 36-inch soundbar is low enough to sit right under the TV, without obstructing the IR sensor.

At first glance, the Vizio SB3621 is a low, rectangular device that is all-black, except for the aluminum end caps that bear the Vizio logo. The front and top surfaces of the Vizio SB3621 are covered in a black mesh that could become a dust magnet in certain environments. The bottom and back surfaces are made of black plastic.

Because the SB3621 is a budget soundbar, it doesn’t have much in the way of a display. You’ll have to settle for a column of LEDs at the left-hand side of the device. The top surface of the soundbar holds a few controls, namely power, input, Bluetooth and a pair of volume buttons.

Design: Woofer

The 5.3-inch wireless woofer is slim and compact, allowing it to fit in snug spaces. It has a power port, a power button and a Bluetooth pairing button. The front of the woofer is a plain aluminum surface with black trim, a vent and the Vizio logo.

There are rubber pads on two of the woofer’s surfaces and this allows you to choose a vertical or horizontal configuration for your setup. It’s little things like these that make it the best budget sound bar.

Inputs and outputs

The soundbar has Bluetooth connectivity that allows you to pair an extra audio device as well as an input source. All you need to do is hold down the pairing button at the top of the soundbar and the soundbar appears as a pairing option on your phone or PC.

The Vizio SB3621 also has a nice selection of inputs that match the ones on most TV sets. These go with the cables that ship with the soundbar. At the back of the SB3521, you will find an optical audio port, a 3.5mm audio jack, a digital coaxial/SPDIF input and a power port. If you can, connect the TV and the soundbar via the optical ports. This way you get to enjoy the best possible sound quality.

Lastly, the soundbar has a USB port that you can use to play .mp3 and .wav sound formats directly from a connected device.

Setup

Because the SB3621 will automatically detect a TV and its woofer, setup is simply a matter of powering the soundbar and connecting it to the TV. You can use any of the input ports listed above to do so. As for the woofer, you only need to switch it on and enable Bluetooth. It’s worth noting that the optical cable that comes with the soundbar is fairly short, so you’ll need to keep the soundbar close to the TV.

Once you’ve hooked up the soundbar, the sound will channel from the TV to the internal speakers of the sound bar. The low-frequency sound goes to the woofer, which takes care of the bass.

Ease of use

We’re used to digital displays that tell you the input port that’s currently in use, or the volume level of the soundbar. The Vizio SB3621 does not have one of those. Instead, you’ll need to learn the meaning of each LED on the soundbar. You will also have to learn what different combinations of flashing LEDs mean.

The user manual will help a little, but you may have to go to the internet to supplement the instructions that ship with the soundbar.

Another factor that will pose a challenge is the buttons on the remote and the soundbar itself. They are level with the surfaces they sit on, which could take some getting used to. This design choice becomes more noticeable as you try to change input sources or adjust the volume in a dim room.

Remote

The remote has useful shortcut buttons that make it easy to navigate the soundbar. The top row has the power, input and Bluetooth buttons. Right below it is a navigation pad that’s fun to use. Below the navigation pad are shortcut keys to different sound modes and equalizer options.

Sound quality

The best budget sound bar has two 3.5” forward-facing internal drivers. Together with the 5.3” rear-firing driver in the subwoofer, the whole setup has an output of 100 Watts, which is impressive. The soundbar decodes basic Dolby and DTS content to render something close to crisp surround sound.

For an affordable soundbar, the Vizio SB3621n packs a powerful punch. The soundbar manages to bounce sound off different surfaces, giving you the impression that the TV is generating sound from several places at once.

The subwoofer can render sound that goes as low as 50Hz. It can deliver the blasts and thumps from your favorite action scenes without breaking a sweat. That said the bass does get muddled at high volume, so you will need to find a sweet spot in order to enjoy clear, defined sound.
