LG Soundbar S40TR

Technical details

For movie nights in a living room where a full-size receiver setup would take up more room, the LG S40TR combines a soundbar with rear surround speakers and a wireless subwoofer. Its 4.1-channel layout is designed to add more depth and impact than TV speakers alone, while keeping the main setup relatively compact.

Dolby Audio, Dolby Digital, and DTS Digital compatibility cover supported shows, movies, and music. Clear Voice Plus is intended to make dialogue easier to follow, and AI Sound Pro is listed as a sound feature. The metal grille also helps keep dust and debris out of the soundbar.

Everyday compatibility

The wireless rear speakers avoid the need for a special receiver, and the subwoofer is wireless too. That can make this a more practical route to surround-style sound than a receiver-and-speaker system, especially if you want fewer components around the TV. Wireless does not mean the speakers disappear from the room, though: you still need a suitable place for the rear units and subwoofer.

LG TV owners get the clearest added convenience. The WOW Interface lets you adjust soundbar settings and select sound modes using the TV remote, while WOW Orchestra can play audio through the TV and soundbar together. Those functions are specifically described around an LG TV, so they should not be treated as universal TV features. It suits you if you want a coordinated LG TV and soundbar setup without managing separate controls.

Usage tips

For a movie, place the rear speakers behind or beside the main seating area so their contribution is easier to notice, then position the subwoofer where it fits without blocking your usual path through the room. A scene with quiet dialogue followed by a fuller action sequence is a useful way to judge whether Clear Voice Plus and the extra surround components suit your listening habits. The system is also described for music and everyday shows, not just films.

From the way it is set up, the S40TR is more involved than adding a single soundbar and stopping there: its rear speakers need a place in the room. If your layout leaves no sensible spots for them, the surround setup may be less useful than a simpler soundbar. The product description does not provide connection details for non-LG TVs, so avoid assuming that every WOW control feature will work with another brand.

Questions before you buy

Does it include rear speakers? Yes. The listed setup includes wireless rear surround speakers as well as a wireless subwoofer.

Can you control it with an LG TV remote? The WOW Interface is described as allowing control of the soundbar and LG TV with one remote, including volume, audio settings, and sound modes.

Is it only for movies? No. The stated uses include shows and music as well as movies, with Clear Voice Plus aimed at clearer conversations.

Buying verdict

The LG S40TR makes sense if you want a more cinematic, multi-speaker setup without moving to a separate receiver, and you have room to place the rear speakers. It also has a practical advantage for an LG TV setup through its shared controls and WOW Orchestra feature. Not the best choice if you want a single compact bar with no extra speakers to position, or if your priority is confirmed TV-brand compatibility beyond the LG features described here.
