I had a chance to test and compare two models: Polk Audio Command Bar vs LG SP7R and this review should help people who are looking for a good soundbar. The Polk Audio Command Bar was rated 6.6, while the LG SP7R has a rating 5. The soundbars are equipped with a different number of buttons, volume down, volume up, microphone, action for the Command Bar and power, source, demo, volume down, volume up for the SP7R.
Each of the models under consideration has active amplification type. A noticeable difference is the number of channels that Command Bar has 2.1 and SP7R has 7.1. These rivals can be compared in terms of power, 160 (overall) versus 580 (overall) according to devices. The built-in subwoofer is not implemented in any of these models. An external subwoofer can be connected to any of the units in this comparison. Rate 6 out of 10 received the Polk Audio Command Bar for audio features and specs, but the LG SP7R received 8 out of 10.
Soundbars do not have AirPlay support. The Command Bar can play audio from Spotify.
Both models do not have a wireless Wi-Fi interface. Soundbars from this comparison have Bluetooth support. 1/1 HDMI inputs/outputs are in each of soundbars. As in the Command Bar, so in the SP7R there is the HDMI Audio Return Channel (ARC). Connecting devices via USB is possible in both models. The connectivity of each of the models was estimated at 7/10. None of these soundbars can be controlled using the app. The Polk Audio Command Bar equipped with a microphone. The Polk Audio Command Bar may become part of a multiroom system.
Dolby Atmos audio decoder support is not implemented in either the Command Bar or SP7R. Devices from this comparison cannot process surround sound due to lack of DTS:X. The Command Bar was rated 5/10, while the SP7R received a mark of 6/10 for multichannel surround.
