The Arc is rated 5 of 10 against 8 for the SL9YG according to the audio features rating.
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 Arc and the SL9YG.
There are stereo soundbars and multichannel ones. It is with the help of multichannel devices that you can get volumetric sound.

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. The SL9YG comes with an external subwoofer. Competitors support wireless connection to a separate external subwoofer.

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 Arc received rating 4 out of 10 for multichannel audio processing, but the SL9YG, in the same category, earned 8 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. If we consider the models in terms of support for Dolby Atmos, then both soundbars can work with this technology.
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 SL9YG.

The existence of a sufficient number of current connectors significantly expands the functionality of the device. For example, only through HDMI is it possible to implement the transfer of object-oriented formats, and the presence of a Bluetooth connection will allow remote control, etc. Connectivity of competitors was rated 7 out of 10.
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 both devices.
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 Arc has 1/0 HDMI inputs/outputs, but the SL9YG got 1/1 HDMI inputs/outputs from the manufacturer.
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.

Voice control is designed to make operating the device more convenient. This allows you to control basic soundbar functions from anywhere in the room.
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. Both soundbars have 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. The SL9YG has the ability to use a multiroom system.
