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 Home Sound Bar 550 and the Arc.

There are stereo soundbars and multichannel ones. It is with the help of multichannel devices that you can get volumetric sound.

DTS:X is an algorithm for processing sound scenes by the processor, linking directly to objects, rather than channels, and calculating the optimal distribution of sound output in a room. The manufacturer has implemented DTS:X technology only in Home Sound Bar 550.
