Comparison of LG GX and Samsung HW-LST70T will allow us to get comprehensive information about the features of these two devices. And as a result of the comparison, it becomes clear that HW-LST70T is inferior in all characteristics to GX. According to the results of our comparison, GX received 6.5 points out of 10 possible, and HW-LST70T was rated 6.4 points.
The GX is rated 7 of 10 against 6 for the HW-LST70T 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 GX and the HW-LST70T.
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 GX has 3.1 channels, while the HW-LST70T has 3.0 channels. Also, the output power of the soundbars under consideration is different, LG GX has 420 (overall) W, and 210 (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. A built-in subwoofer is only present in the HW-LST70T. The GX 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 GX received rating 10 out of 10 for multichannel audio processing, but the HW-LST70T, in the same category, earned 5 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 GX.
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 GX.

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. The devices received different ratings for connectivity: LG GX was rated 8 out of 10, and Samsung HW-LST70T was rated 6 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 the HW-LST70T.
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 GX has 1/1 HDMI inputs/outputs, but the HW-LST70T got 1/0 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 a feature unique to LG GX. Connecting external devices via USB can be done on both models.

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. Only Samsung HW-LST70T 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. The HW-LST70T has the ability to use a multiroom system.
