l would like to share my experience after comparing and testing two soundbars – VIZIO SB3820-C6 vs VIZIO SB4451-C0. The VIZIO SB3820-C6 was rated 5.2, while the VIZIO SB4451-C0 has a rating 7.2. Soundbars have the same set of buttons - power, input, Bluetooth, volume down, volume up.
Each of the models under consideration has active amplification type. A noticeable difference is the number of channels that SB3820-C6 has 2.0 and SB4451-C0 has 5.1. The built-in subwoofer is not implemented in any of these models. Rate 5 out of 10 received the VIZIO SB3820-C6 for audio features and specs, but the VIZIO SB4451-C0 received 8 out of 10. The SB4451-C0 can play audio from Spotify.
Wireless Internet connection is realized only in the SB4451-C0. Soundbars from this comparison have Bluetooth support. The HDMI Audio Return Channel (ARC) is implemented only in the SB4451-C0. Connecting devices via USB is possible in both models. We rated the connectivity of the SB3820-C6 at 6 out of 10, while the SB4451-C0 was rated 8/10.
Each of the soundbars can be controlled using the application. Soundbars in this review are not equipped with a microphone. The VIZIO SB4451-C0 may become part of a multiroom system.
Dolby Atmos audio decoder support is not implemented in either the SB3820-C6 or SB4451-C0. Devices from this comparison cannot process surround sound due to lack of DTS:X. The same score of 4/10 was put to the soundbars for multichannel surround support.
