Audio features

The S75QR is rated 8 of 10 against 4 for the DHT-S217 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 S75QR and the DHT-S217.

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 S75QR has 5.1.2 channels, while the DHT-S217 has 2.1 channels. Also, the output power of the soundbars under consideration is different, LG S75QR has 450 (overall) W, and 40 (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 DHT-S217. The S75QR comes with an external subwoofer. LG S75QR has the ability to handle wireless connections from an external subwoofer, while Denon DHT-S217 only has wired connections.

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 S75QR received rating 6 out of 10 for multichannel audio processing, but the DHT-S217, 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. 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 S75QR.

Streaming services

The possibility to listen online to millions of songs from one device has become a reality thanks to streaming services.


None of the two models is not implemented AirPlay function. The popular Spotify service cannot be used on both soundbars.

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. Such connection as via Wi-Fi is not possible on any of the devices in comparison.

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.

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 DHT-S217 has its own remote control application. None of these 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. However, it is impossible to create a multiroom system based on each of these soundbars.
