Buying Guide: What to Look for in a LG Soundbar

Channel Configuration and Audio Channels

The number of channels determines how immersive your soundstage feels. A 2.1 channel system like the LG S40T delivers solid stereo sound with a dedicated subwoofer, perfect for small rooms or casual viewing. For a true surround experience, step up to a 5.1.3 or 7.1.3 configuration found in the S80TR and S90TR. These include rear speakers and up-firing drivers that bounce sound off the ceiling, creating a bubble of audio that puts you inside the movie. If you often watch action films or play games, prioritize models with at least 5.1 channels.

Wireless Connectivity and WOWCAST

LG’s WOWCAST technology lets you transmit Dolby Atmos wirelessly from your TV to the soundbar without visible cables or audio lag. The S80TR and S90TR both have WOWCAST built in, making setup a breeze. The S40T uses a standard wireless subwoofer but lacks the advanced wireless Atmos feature. For a clean, clutter-free installation, especially if your TV is wall-mounted, a soundbar with WOWCAST is a major advantage.

Room Calibration and Sound Optimization

Every room has unique acoustics. LG’s Advanced Room Calibration uses the soundbar’s built-in microphone to measure your space and adjust the audio output accordingly. This feature is available on the S80TR and S90TR, ensuring you get balanced sound whether your room is square, long, or filled with furniture. The S40T relies on manual EQ adjustments via the LG Soundbar App. If you want a set-and-forget solution, opt for a model with automatic calibration.

Dialogue Clarity and Up-Firing Speakers

Clear dialogue is essential for enjoying movies and shows. LG’s center up-firing speaker, found in the S80TR and S90TR, focuses vocal frequencies so you hear every word even during loud action scenes. The S40T uses Clear Voice Plus, which analyzes audio to enhance speech. For a home theater that rivals a cinema, the up-firing center channel makes a noticeable difference. If you watch a lot of news or dialogue-heavy content, this is a key feature to prioritize. For more tips on matching soundbars to specific TVs, read our article on best soundbars for hisense TV.

After reviewing LG’s lineup, our top recommendation for a full home theater experience is the LG S90TR 7.1.3-Channel OLED evo TV Matching Home with its seven channels, wireless rear speakers, and WOWCAST built in. It delivers breathtaking Dolby Atmos sound that fills any room. For those on a tighter budget or with limited space, the LG S40T 2.1 ch.Soundbar with Wireless Subwoofer offers excellent value with clear dialogue and a compact design that still packs a punch. Whichever you choose, you will transform your TV audio into something truly immersive.
