It worth understanding the difference between the two types of amplification: a passive soundbar does not have its own amplifier and receives amplification from the signal source, while an active soundbar has a built-in amplifier. The same active type of amplification is used in the Shockwafe Pro 7.1 eARC and the HW-A550.

There are stereo soundbars and multichannel ones. It is with the help of multichannel devices that you can get volumetric sound. It is worth noting one of the main differences, the Shockwafe Pro 7.1 eARC has 7.1.4 channels, while the HW-A550 has 2.1 channels. Also, the output power of the soundbars under consideration is different, Nakamichi Shockwafe Pro 7.1 eARC has 850 (overall) W, and 410 (overall) W has the competitor.

Soundbars can have a built-in or external subwoofer. The first type is inseparable from the soundbar body, but for the second, you can choose a good location for deep bass. Both reviewed devices are equipped with an external subwoofer. Competitors support wireless connection to a separate external subwoofer.
