I had a chance to test and compare two models: VIZIO SB4451-C0 vs LG SK1 and this review should help people who are looking for a good soundbar. The VIZIO SB4451-C0 was rated 7.2, while the LG SK1 has a rating 4.5.
Each of the models under consideration has active amplification type. A noticeable difference is the number of channels that SB4451-C0 has 5.1 and SK1 has 2.0. The built-in subwoofer is not implemented in any of these models. Rate 8 out of 10 received the VIZIO SB4451-C0 for audio features and specs, but the LG SK1 received 5 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 SB4451-C0 at 8 out of 10, while the SK1 was rated 6/10.
The manufacturer of the SB4451-C0 provides a device control 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 SB4451-C0 or SK1. 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.
