Review on Sound bar LG SJ3 black by Somsak Pasalae ᠌

Revainrating 3 out of 5

There are pros and cons, think before buying.

Not very suitable for listening to music. On the device, in addition to the fact that the speakers themselves are very tall, by default, the device also overestimates frequencies that are higher than 2 kHz, especially high frequencies, there are a lot of them, and this cuts the ear. There is no equalizer on the soundbar. Therefore, in order to somehow correct the situation, I disassembled the device in order to gain access to the signal wires that go to the bar's speakers and tested the frequency response. By a simple experiment, I checked which and how much the frequencies are overstated. Then I installed the EqualizerAPO program on a laptop, which I connected to the soundbar and reduced by 2-3 dB all frequencies from 2.5 kHz (2.5k -2db; 4k -3db; 6.3k -3db; 10k -3db, 16k - 3.5db.) And raised the frequencies from 250 to 1k by 1.5 - 2db. because they fail. And the sound became more or less listenable, and without equalizer adjustment it is impossible to listen. I listened to music in the "Standard" mode. There is also the "Cinema" mode, it is worth noting that with this mode the sound becomes more voluminous, bass. It's probably good for TV and movies. But it's still a distortion of the sound material. If the soundbar had outputs for connecting third-party acoustics, as well as a custom equalizer, it would be much better. Well, it would not hurt to be able to connect several devices at once, for example, a laptop and a smartphone at the same time, otherwise you have to turn off the device to connect another.

Pros
  • Good subwoofer, powerful, wireless and with a cool unusual coverage. Cinema mode, in which the sound becomes more voluminous and bass.
Cons
  • Too many high frequencies that cut the ear (more on this in the comments). Mid frequencies are not very good. No equalizer. No audio outputs. Few different entrances. No cable to connect to TV. The lack of a display, for this money they could have made a display for at least a few characters so that it was clear what the volume level, subwoofer level, etc. were. Samsung has a cheaper model and that is a display))
