Review And Discussion
VIZIO, despite being a newer company, has become a popular producer of budget-tier home theater equipment. The SB2920-C6 sound bar is a particularly cheap and very easy way to augment mediocre default TV speakers.
The SB2920-C6 brings a lot to the table for the modest price-tag. While it wont compare with a full fledged 2.1 set up, 95 dB of max volume (presumably at close range) is plenty to make a TV sound sufficient for near/mid-field listening.
The real appeal of such a sound bar though is how easy it is – it’s slim, only 5 lbs, and easy enough to place right under a TV, or to wall mount it. All the mount hardware comes included. It’s a powered meaning you don’t need to worry about receivers or speaker cable or anything like that – just hook it up via any of the standard connections (cables come included), or you can stream directly to it via Bluetooth if you like.
The response range is decent but not stellar, and we’d honestly expect for the response curve to falter before the sound hits 70 Hz, but this is a usual limitation for not just sound bars but most bookshelf speakers too. If you really want full bass and maximal reproduction, a subwoofer is almost always in order. VIZIO actually makes 2.1 soundbars that come with a subwoofer, but they’re a little more expensive. We recommend the SB3821-C6 if that interests you.
VIZIO offers a 1 year warranty on its speaker products, which is pretty bare minimum but fairly standard for budget-tier sound bars.
The intent of the SB2920-C6 is pretty clear: if you’re looking for a cheap, easy, and noninvasive way to upgrade crummy default TV speakers for regular watching of sports, talk shows, etc, then this sound bar is definitely a great option.
On the other hand, if you’re looking for a true home theater experience that maximizes music and the full range of sound all the way down to movie explosions, then bigger bookshelf speakers and a subwoofer that can house full sized drivers might be a better choice.
