Comparing Polk Audio SIGNA S2 and Samsung HW-Q70R, all pros and cons of devices become clear. Advantages have shown that HW-Q70R has advantages over SIGNA S2 mainly in terms of audio performance. According to the results of our comparison, SIGNA S2 received 5 points out of 10 possible, and HW-Q70R was rated 7.6 points.
The SIGNA S2 is rated 6 of 10 against 7 for the HW-Q70R 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 SIGNA S2 and the HW-Q70R.
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 SIGNA S2 has 2.1 channels, while the HW-Q70R has 3.1.2 channels.

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 SIGNA S2 received rating 4 out of 10 for multichannel audio processing, but the HW-Q70R, 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 Samsung HW-Q70R.
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 HW-Q70R.

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: Polk Audio SIGNA S2 was rated 6 out of 10, and Samsung HW-Q70R 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 the HW-Q70R.
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 SIGNA S2 has 1/0 HDMI inputs/outputs, but the HW-Q70R 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.
