Higher-end televisions these days comes with not-so-powerful speakers, required to produce optimum sound.

As a result, you need external Speaker set for your TV for a better audio experience.

Check out our Vizio SS2521-C6 review and let me convince you; how it’s the best budget speaker system that you need for your brand new TV.

Vizio SS2521- C6 is a 25-inch 2.1 channel sound stand that is designed to act directly as a stand for your TV.

It offers a budget and affordable alternative solution for the not-so-powerful speakers in your TV.

The front of the Vizio sound stand is triangular in shape, which will allow for wider dispersion of sound.

The package comes with a compact remote and includes cables for all kind of inputs.

The TV stand comes with a sleek frame, which will be a great fit to the TVs up to 55-inch category.

The design is very elegant and fits into tight spaces and offers great sound.

You get incredible sound from the speaker and deep thumping bass from the in-built a subwoofer and the sound is loud enough to fill a small hall or a medium size room.

The VIZIO SS2521-C6 Sound Stand offers peak sound output up to 101dB with less than 1% harmonic distortion and is capable of supporting TVs, weighing up to 60lbs.

The display on the sound stand has a very low key and minimal design.

There’s a row of LEDs present at front that are neatly hidden behind the grill.

These LEDs convey different status by lighting up or blinking in various ways. However I do recommend to go through the provided manual to know what different LED status mean.


Setting Up: Getting Started

Setting up the Vizio SS2521-C6 is very simple and read ahead to know how to do it.

Usually, installation require placing the sound bar under the TV and making appropriate connections.

To get things started, you need to connect the sound stand to your TV with the help of the digital-audio cable (provided in the package), plug in the power and change audio settings on your TV as Vizio SS2521-C6 sound stand as your default audio source.

However do make sure that you do not keep TV bigger than 55-inch on the sound stand as recommended by the company or else might end up seriously damaging the soundbar.

Moreover the I/Os provided at the back are RCA, 3.5mm jack, optical and RCA coaxial, however HDMI port is missing in this budget sound stand from Vizio.

This Vizio TV Sound Stand decodes Dolby Digital and it also offers DTS TruSurround HD, TruVolume and Studio Surround processing.

It also offers controls for Bass and Treble. The sleek profile of The VIZIO 25-inch Sound Stand allows it to blend it easily with the TV. It is almost not-noticeable when kept under a TV.

Considering the price, the sound stand gives clear sound even at high volume and knocks the sock off of your TV speakers any given day.




Out of the box, you might not be impressed with the sound quality of Vizio SS2521-C6.

It does need some tweaking and adjustment in equalizer in order to produce its best sound.

Moreover do make sure to keep the sound stand atleast 6 inches away from walls and not put on a TV which weighs heavily. As this might affect the overall sound performance.

There are various sound enchancement features like TruSurround HD, however it may or may not work for you depending on the soundbar’s placement, try turning the feature ON or OFF and see what works best for you.

One of the other I believe that might affect performance is the height at which the sound stand might be placed.

I recommend to keep it on a heighted table which will be at ear level while sitting.

However getting the good sound isn’t as complicated as it seems, you just need to adjust the sound in the first couple of days and you’re set for life.
