The LG S40TR 4.1 ch. Home Theater Soundbar sits between your TV and your room, adding four channels of amplified sound with a wireless subwoofer and a pair of wireless rear speakers. At $199.99, that works out to about 10 percent below the typical price over the last 90 days, which we'd consider a fair entry point for a full surround layout.
Dolby Digital and DTS Digital decoding cover the audio formats most streaming apps and Blu-ray discs carry, so dialogue, effects and music get routed across the bar and its satellites instead of squeezed into your TV's built-in speakers. Clear Voice Plus pushes center-channel dialogue forward, which matters if you struggle to follow conversation during quiet scenes.
The rear speakers handle the surround cues that make a movie feel wider than the screen, and they connect wirelessly, so you don't need a separate receiver to place them behind your seat. The wireless subwoofer covers the low end that small TV speakers usually lose. We'd skip this bar if you want object-based formats like Dolby Atmos or DTS:X, since the S40TR supports Dolby Digital and DTS Digital.
Connecting the bar and what each remote controls
If you own an LG TV, WOW Orchestra lets the TV speakers and the soundbar play at the same time, and WOW Interface routes volume, sound modes and connection status through the TV remote. That pairing is the reason to pick this model over a generic bar, because you keep a single remote instead of juggling two.
Outside LG TVs, plan on the standard connections your source gear offers. Check whether your TV has an HDMI ARC or optical output that can feed the bar, and confirm the soundbar's inputs match before you buy, because the rear speakers are wireless but the main signal still needs a wired link from the TV.
The LG Soundbar App provides a three-band equalizer for bass, mid-range and treble, and Smart Up-Mixer uses the full speaker array to widen two-channel audio. Both are easy ways to tune the system to your room without buying anything extra.
Which room suits this system and which buyer should pass
This layout suits a living room or bedroom where you want rear-channel effects but can't run speaker cable behind the couch. The wireless rear speakers and wireless subwoofer mean the only cable concerns are power outlets near each speaker and the connection from your TV to the bar.
Before ordering, measure the space beside your TV for the bar, confirm an outlet or power strip reaches each rear speaker position, and check that your viewing seat has room behind it for the satellites. A 4.3-star average from 625 ratings suggests buyers generally find the setup workable, though the rating is not a substitute for checking your own room.
If you want the most immersive current format or plan to expand to more channels later, this bar's Dolby Digital and DTS Digital support is the limiting factor, and we'd look at a model with Atmos instead. For a straightforward 4.1 surround upgrade on an LG TV, the S40TR covers the basics at a price below its recent typical.
Wireless rear speakers need power outlets, so measure those spots before ordering.
Check your TV's HDMI ARC or optical output so the bar has a clean signal path.
Confirm your LG TV model if you want WOW Orchestra and one-remote control.
