Design and build

The LG SN4R bar follows the same aesthetic that predominates in LG models, where the minimalism is a key factor so that it goes unnoticed in the living room. The construction remains the same, employing a plastic chassis and a front grille to cover the speaker area. Its economical price is evident in the choice of materials with a clear predominance of plastic even for the grid. However, the finishes are good and show a plot that makes you win integers.

With a total length of 89 cm, it makes its use suitable for televisions starting at 40 inches. Its height of 5.7 cm does not prevent it from being embedded under the lower frame of a screen, integrating the bar into the whole living room. In the central part we have a practical display that shows the different available inputs or the sound values. The connectors are arranged at the rear, so the cables will not be visible.

They accompany him to the bar two extra speakers for an immersive living room experience. These speakers together with their wireless receiver are part of the kit LG SPJ4-S. These speakers are wireless but require a wired power supply, no batteries can be inserted. The LG SN4R’s subwoofer is also wireless, with a height of 39 cm and a weight that reaches 5.3 kg.

Sound quality and features of the LG soundbar

The LG SN4R sound system has a total power of 420W RMS, in a channel distribution 4.1. Of those, 120 W belong to the soundbar, 180 W supplies the subwoofer and the other 120 W distributed between the two rear speakers. This sound bar will delight users who are looking for an economical product but without sacrificing a high power level. However, it is not one of the best equipped models in the LG catalog, since it lacks some technologies such as Dolby ATMOS that the LG SN9YG does include.

However, the LG SN4R has a lot to offer as its AI Pro technology, responsible for automatically analyzing content to optimize audio settings. A simultaneous adaptive audio system that provides a better balance of frequencies for a rich experience of nuances. Something that is especially noticeable when we go from a sports broadcast to a movie, where the bass and treble level tend to be uneven.

It has an adaptive audio system that provides a sound experience faithful to the content

In the sound settings we find several ways to take full advantage of the capabilities of the LG bar. For example, the Bass Blast boosts the bass level which can be useful for different music genres or in action movies. As well as the DTS Virtual: X to offer the surround sound that we all want to have at home. Finally, it is compatible with various audio formats of which we highlight DTS, Dolby Digital, LPCM, MP3 or WMA.

Connectivity and user experience

Connectivity is another of those essential sections in a sound bar. This LG SN4R is not far behind by incorporating the Bluetooth 4.0 connectivity for the TV or link other devices such as phones. A quick and easy way to connect any device that has such a connection and deliver a more powerful sound. Nothing better than arriving from work and activating our playlist of Spotify while we prepare dinner.

LG SN4R

With Bluetooth connectivity, optical input, USB file reading and two HDMI 1.4

We can also make use of your optical input or choose your HDMI 1.4 input and HDMI ARC output. Currently, it is the most used option due to its ease of use. This way we will have our bar ready when we turn on the TV, control its functions and volume from the TV remote control and we also get a higher sound quality. The synchronization with the input source is flawless, while by BT it can cause some micro-cut or lack of synchronization with the image.
