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 M21d-H8 and the SN9YG.

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 M21d-H8 has 2.1 channels, while the SN9YG has 5.1.2 channels.

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. A built-in subwoofer is only present in the M21d-H8. The SN9YG comes with an external subwoofer.

Multichannel surround

Unlike stereo, when reproducing multichannel sound, each specific direction of sound corresponds to its dedicated channel with a separate independent loudspeaker, which creates a three-dimensional sound stage. The M21d-H8 received rating 5 out of 10 for multichannel audio processing, but the SN9YG, in the same category, earned 10 out of 10 points.

The peculiarity of Dolby Atmos is that this format is object-oriented, that is, each object of the audio signal is sounded separately and linked to its spatial location. Dolby Atmos surround sound support is implemented only in LG SN9YG.

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 SN9YG.
