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 SN9YG and the SN4Y.

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 SN9YG has 5.1.2 channels, while the SN4Y has 2.1 channels. Also, the output power of the soundbars under consideration is different, LG SN9YG has 520 (overall) W, and 400 (overall) W has the competitor.

Subwoofers

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.

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 SN9YG received rating 10 out of 10 for multichannel audio processing, but the SN4Y, in the same category, earned 6 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.

The presence of Wi-Fi in the soundbar allows you to get rid of wires when connected to a sound source and get minimal audio latency when playing content from streaming services. Wireless connection via Wi-Fi is possible on the SN9YG.

Bluetooth connection is now one of the main communication protocols for speaker systems, which provides excellent quality and minimal audio latency. The availability of Bluetooth protocol, we can see in both models. The competitors in this comparison has 1/1 HDMI inputs/outputs.

HDMI ARC is a very usefull technology that creates a two-way communication channel between a TV and another device. This is convenient since there is no need to use optical and other cables in the system. HDMI ARC is basic for both soundbars. Connecting external devices via USB can be done on both models.

Proprietary applications allow you to control your soundbars remotely. This is possible both via Bluetooth and Wi-Fi. The ability to control the soundbar using the application is implemented in each of the competitors. Only LG SN9YG has a built-in microphone.

Some soundbars can be part of a multi-room system and it is an affordable solution for sounding the whole house. However, it is impossible to create a multiroom system based on each of these soundbars.
