l would like to share my experience after comparing and testing two soundbars – Polk Audio Command Bar vs Klipsch Cinema 400. The Polk Audio Command Bar was rated 6.6, while the Klipsch Cinema 400 has a rating 4.6.
Each of the models under consideration has active amplification type. By the number of channels, the devices do not differ. These rivals can be compared in terms of power, 160 (overall) versus 400 (overall) according to devices. The built-in subwoofer is not implemented in any of these models. An external subwoofer connects to the Command Bar via wireless, but Cinema 400 has wired connection type. Rate 6 out of 10 received the Polk Audio Command Bar for audio features and specs, but the Klipsch Cinema 400 received 5 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. There are 1/1 HDMI inputs/outputs in the Polk Audio Command Bar versus 1/0 HDMIs in the Klipsch Cinema 400. As in the Command Bar, so in the Cinema 400 there is the HDMI Audio Return Channel (ARC). We rated the connectivity of the Command Bar at 7 out of 10, while the Cinema 400 was rated 8/10. 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 Cinema 400. Devices from this comparison cannot process surround sound due to lack of DTS:X. The Command Bar was rated 5/10, while the Cinema 400 received a mark of 6/10 for multichannel surround.
