What owners say about the LG S40T

Based on 75 owners sharing their experience in online comments

55%positive5%mixed40%negative

Owners praise the clear sound, strong bass, and value, while connectivity faults and uneven bass or audio reliability temper praise.

What owners dislike

  • Some owners find the sound weaker than the advertised 300W, with less volume and less deep, punchy bass than rival soundbars.5
  • Some owners cannot get HDMI ARC working: audio stays on the TV speakers or a lock icon appears; optical or Bluetooth works instead.5
  • Some owners say Bluetooth drops out during playback, the phone cannot find the soundbar, and it can switch off and disconnect.4
  • Some owners find the subwoofer too quiet, with bass so faint they have to press an ear to the box to hear it.4
  • Some owners report sound cutting out every few seconds, stuttering or muting for about two seconds at a time, even at close range.4
  • Some owners cannot pair the subwoofer, whose light keeps blinking without connecting, and one reports it stopped working after two days.3
  • Some owners find the remote not very intuitive, one needed a replacement after it broke, and another could not get it to work.3
  • Owners find bass too strong in small rooms, where it reverberates, so they lower the subwoofer level or shift bass settings to calm it.3

Third-party reviews

What customers like about LG S40T

  • A wireless subwoofer means no cable from the bar to the bass unit.
  • The subwoofer is included, so the bass works from day one.
  • The bass reaches down to 20 Hz.
  • Voices come through clear and balanced, good for news and podcasts.
  • Bass and treble can be adjusted with the remote.
  • HDMI ARC, optical and USB inputs cover most connection needs.

What customers don't like about LG S40T

  • Only two channels, so there is no real surround effect.
  • No display, just indicator lights on the unit.
  • Instruments can sound muffled and lack fine detail.
  • Rooms larger than 300 to 350 square feet are a stretch.
  • No Wi-Fi, Chromecast or AirPlay for streaming.

Verdict

If most of your listening is news, series and podcasts, the LG S40T is a sensible 2.1 bar with a wireless subwoofer. Voices come through clear and balanced, and the bass stays controlled. The bass goes down to 20 Hz, which adds real weight to films. Bass and treble can be adjusted with the remote, and dialogue enhancement helps speech stand out. It is loud enough for small to medium rooms, but it is not ideal for large halls. The trade-offs are no surround effect, as there are only two channels, and no display, just indicator lights on the unit. Instruments can sound a little muffled, so music lovers may want more detail. It suits a buyer who wants a clear TV upgrade without a long list of features.
