Vizio SB2920-C6 and SB3820-C6 Sound Bars

Satisfying Sound at a Sensible Price

Sound bars have been a welcomed addition by many consumers who desire better sound quality from the otherwise mediocre audio output delivered by most flat panel televisions.

Today’s sound bars are designed to blend seamlessly with practically any HDTV screen size available, whether it be a wall mount or table top setup.

In this product profile, I will take a look at two very popular sound bars; in fact, these two products from Vizio are the #1 and #2 best selling sound bars currently available from

The SB2920-C6 is a 29” two channel system containing 2 x 2.25” full range drivers which technically cannot produce full range sound with a rated frequency response of 70 Hz –19 kHz. This means mid and low bass frequencies will be lacking with this sound bar. However, this speaker does contain a subwoofer output which allows for a stand-alone subwoofer to be connected via a RCA output to fill in the lower bass frequencies.

For 2015, Vizio has redesigned their sound bar enclosures which now feature a sleek rectangular shape with silver end caps. There are several LED status indicators along the left hand side of the speaker. On top of the unit are five control buttons for Bluetooth input, volume up, volume down, source input and power.

The systems Bluetooth capability allows for wireless audio streaming from your mobile devices. This is a feature I have enjoyed on previous Vizio sound bars I have evaluated.

The supplied remote control is a small yet functional device that contains all the essential buttons to operate the SB2920-C6 from your favorite viewing position. It will even control the volume of a separate subwoofer.

The SB2920-C6 contains several connectivity options for such an inexpensive sound bar. Connections include:

  • 1 Analog stereo RCA input
  • 1 Analog 3.5mm stereo mini jack
  • 1 Coaxial digital audio input
  • 1 Optical digital audio input
  • 1 RCA subwoofer output
  • 1 USB input


  • Attractive sleek design
  • Good sound quality
  • Inexpensive
  • Bluetooth capability
  • Multiple connectivity options


  • Lacking low bass output
  • Remote is not programmable for control of other devices
  • No direct access to inputs from remote or sound bar


  • 29”W x 3”H x 3”D


  • 4.5 lbs.

The SB3820-C6 is essentially a 38” version of the SB2920-C6 with the exception of a few key differences:

The SB3820-C6 adds 2 x 2.75” full range deep bass modules (drivers) for extended bass output when compared to the SB2920-C6’s 2 x 2.25 drivers. The low frequency response of the SB3820-C6 bottoms out at 60Hz versus the SB2920’s 70Hz.

The SB3820-C6 will also play louder producing sound pressure levels of up to 100 dB, while its counterpart has sound output levels of up to 95 dB.

Features that are common to both sound bars are Bluetooth capability, identical port connectivity and the same remote control.
