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 Shockwafe Elite 7.2 and the SIGNA S2.

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 Shockwafe Elite 7.2 has 7.2.4 channels, while the SIGNA S2 has 2.1 channels.

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 Shockwafe Elite 7.2 received rating 10 out of 10 for multichannel audio processing, but the SIGNA S2, in the same category, earned 4 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 Nakamichi Shockwafe Elite 7.2.

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 Shockwafe Elite 7.2.

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 Shockwafe Elite 7.2 has 3/1 HDMI inputs/outputs, but the SIGNA S2 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 basic for both soundbars.

Proprietary applications allow you to control your soundbars remotely. This is possible both via Bluetooth and Wi-Fi. In our case, the ability to control the soundbar using the app is not implemented in any of the competitors. 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.
