Vizio SS2521-C6 Sound Stand Review
The Vizio SS2521-C6 is a solid sound stand at this price point. High frequencies and dialogue sound crisp and clean. It's definitely a step-up over TV speakers, but it's not perfect. The 2521's bass and mid-range lack definition which is more of a detriment for music than movies.

Vizio SS2521-C6 Sound Stand Review

Vizio SS2521-C6 Sound Stand Review


The Vizio SS2521 measures 25 x 15.5 x 2 inches and is designed to fit under TV’s 55 inches (60lbs) and under. The front of the SS2521 features a slight triangular shape which we assume helps point the drivers outward to give a wider sound dispersion. Behind the front metal grill lurks two 1.6 inch x 3.6 inch drivers. Bass frequencies are handled by a 4.5 inch subwoofer. Vizio specs out the 2521 as having a frequency response of 55 Hz – 19 kHz.


Vizio SS2521-C6 Sound Stand Connections
The Vizio SS2521-C6 gives you a good amount of connection options. You get (1) analog RCA, (1) digital optical, (1) digital coaxial, (1) 3.5mm, and (1) USB. The only relevant connection you won’t see on the Vizio SS2521-C6 is an HDMI input. The sound stand also includes built-in bluetooth and has Dolby Digital Decoding, DTS TruVolume, and TruSurround . The remote that’s partnered with the 2521 is pretty good. It’s small and compact with large buttons. Unlike, some of their more expensive sound bars, the 2521-C6’s remote does not have a built-in LED display. On the left side of the stand you’ll find a power button, volume controls, an input select toggle button and a bluetooth button.



Vizio is pretty good with supplying you with cables to connect the sound stand to your TV. In the box they give you a digital coaxial, digital optical, RCA and 3.5 mm cable. When connecting the stand to your TV, the user manual suggests that you put your TV to the side of the stand, make your wire connections and then place the TV on top of the stand. This is for good reason. It’s hard to tell from the photos, but the inputs are recessed in the back of the stand. With a TV on top of the Vizio SS2521, it’s extremely difficult to maneuver your hand around back to make the needed connections. If you have a limited amount of space you may have no choice but to connect it with the TV in place. Just be prepared for some grunting and groaning as you contort your hand and fingers to make the wire connections.


Connecting the Sound Stand to your TV is a straightforward process. Choose your connection option, choose the appropriate cable and you’re off and running. One of the more puzzling features of the Vizio SS2521-C6 is its elaborate array of LED lights on the left side. These lights are designed to indicate things like volume control, input selection etc. Outside indicating the volume, these little LED lights are confounding and basically force you to consult the manual as to what they mean. Apple’s made billions of dollars with their simplification of software and hardware. The LED lights on the 2521 are an example of simplification gone awry.


The SS2521-C6 has both DTS-TruSurround and TruVolume. TruVolume is designed to eliminate severe peeks in volume that you sometimes get from different audio content. TruSurround is designed to give you virtual surround sound effects. While it doesn’t deliver on this front, it did open up the sound stage. Because of this, I used the TruSurround in the on position for most of this review.


Sound Quality

The Vizio SS2521-C6 sound stand is small, but it has big sound. When placed in a large 20′ x 30′ room, the Vizio had no problem filling the space with sound although at high volumes, the stand started to crack under the strain. The bass pumped out by the 2521 is a little shocking for a speaker of this size. However, there is a trade-off. At times the bass can get boomy and inarticulate. This was more noticeable with music than movies.


The opening logo intros at the beginning of Edge of Tomorrow on Blu-ray, can be a brutal test for most standalone subwoofers. Considering the small size of the 2521-C6, I didn’t expect it to produce very much audible bass. However, the little box managed to muster up a substantial low-end. Continuing with the movie, the 2521 excelled at reproducing the on-screen action. Explosions were weighty and powerful however, the 2521’s bass is a little overstated . Even with the bass on a medium setting it was overpowering and lacked nuance. Turning the bass down several notches helped. On the other hand, dialogue was clear and focused.


The Vizio SS2521-C6 displayed a wide sound stage from left to right which means no matter where you sit you’ll have a pretty good audio experience. When I stood up in my listening area, the sound was easy to locate below the TV which means you’ll want to have the stand as close as possible to ear height.


For music playback, the 2521’s heavy-handed bass handling was even more apparent. The 2521’s thick heavy bass carried over to higher frequencies which resulted in a muddy mid-range. Vocals, especially female vocals, had good definition. Some male voices on the other hand, suffered from the effects of the muddy mid-range. One other thing of note is that by default the stand’s bass output is really cranked up which resulted in some unwanted vibrations in the TV that I had positioned on top of the stand. Reducing the bass setting helped alleviate this.


The Bottom Line

The Vizio SS2521-C6 is slightly above average in the sound department. For dialogue its detailed and articulate, but the 2521’s heavy-handed bass handling puts a damper on its music playback.
