The LG Soundbar with Rear Speakers Guide: Quick Picks by Room Size

Best for: Small living rooms seeking basic surround sound

The LG S40TR 4.1 ch. Home Theater serves as an accessible entry point for listeners seeking physical surround channels without complex hardware. This package pairs a four-channel soundbar with a wireless subwoofer and dedicated wireless rear surround speakers that communicate without requiring a separate external audio receiver. Engineered around tabletop mounting, the soundbar features LG’s crest exterior design with a durable metal grill that protects the 2.5-inch speaker drivers from dust and environmental debris.

Acoustically, this package relies on Dolby Audio and DTS Digital decoding to extract positional audio from broadcast and streaming media. It integrates Clear Voice Plus technology, which analyzes audio output to enhance dialogue clarity across conversations, alongside a Smart Up-Mixer that converts traditional two-channel stereo tracks into an expanded multi-channel presentation. For households with compatible LG televisions, WOW Orchestra synchronizes the television speakers with the soundbar, while the WOW Interface allows direct setting adjustments through the television remote.

This model is ideal for secondary media rooms, apartments, or smaller living areas where physical rear channels are desired without the ceiling reflections demanded by upward-firing speakers. However, because it lacks dedicated center and height channels, listeners seeking immersive three-dimensional spatial formats will find greater acoustic capability stepping up to the LG S80TR or LG S90TR.

Best for: OLED TV owners wanting balanced spatial audio

Designed specifically to complement modern premium displays, the LG S80TR 5.1.3 ch. OLED evo introduces a substantial leap in three-dimensional audio capability. This system implements a 5.1.3-channel architecture, highlighted by an exclusive center up-firing speaker engineered to project crisp dialogue into the listening area while lifting the soundstage to screen height. The physical rear surround speakers connect wirelessly to eliminate lengthy cable runs across the room, operating seamlessly alongside the dedicated wireless subwoofer.

The S80TR delivers true object-based audio decoding via Dolby Atmos and DTS:X. Advanced Room Calibration utilizes an integrated microphone to measure room boundaries, calculate acoustic reflections, and calibrate frequency response to match room geometry. Connectivity is streamlined through built-in WOWCAST, enabling wireless transmission of lossless Dolby Atmos audio from compatible LG televisions without visible HDMI cables, while Hi-Res Audio certification ensures precise playback of high-bitrate media. Wall-mount hardware is supported for seamless integration beneath wall-hung televisions.

This package suits media enthusiasts and professionals who want genuine height effects and automated acoustic optimization for mid-sized living rooms. While the front bar incorporates upward-firing drivers, the rear satellites provide horizontal surround coverage only; those requiring overhead audio from behind the seating position should consider the top-tier LG S95TR.

Best for: LG QNED owners prioritizing slim TV integration

The LG S70TY 3.1.1 ch QNED TV is engineered with tailored dimensions to fit cleanly beneath modern QNED series screens. Spanning 95 centimeters in width with a slim depth profile, the soundbar nests on standard entertainment furniture or mounts to drywall, offering compatibility with the LG QNED Synergy Bracket. The enclosure features the distinctive crest aesthetic with an all-metal front grill that prevents particulate contamination while blending with contemporary television hardware.

Despite its streamlined proportions, the system delivers 3.1.1-channel audio powered by Dolby Atmos and DTS technologies. It houses an upward-firing center channel dedicated to speech intelligibility, ensuring movie dialogue cuts clearly through background sound effects. Surround Sound Expansion is provided through included 2.0-channel rear surround speakers that communicate wirelessly, removing the necessity for an independent AV receiver. WOW Orchestra and WOW Interface unify speaker synchronization and menu management through the TV screen and television remote.

This model is best suited for owners of LG QNED displays seeking a visually unified setup that enhances speech and delivers surround effects without occupying large amounts of floor or wall space. Where it concedes ground to higher-tier models like the S80TR is in base surround channels, as it features three front channels rather than five discrete baseline directional channels.

Best for: Enthusiasts demanding maximum 3D home theater immersion

Representing the peak of LG’s home acoustic lineup, the LG S95TR 9.1.5 ch Home Theater delivers an uncompromising 9.1.5-channel configuration. The primary soundbar incorporates triple upward-firing channels, including an exclusive center up-firing driver, complemented by an 8-inch wireless subwoofer. Crucially, the rear surround satellites feature integrated up-firing drivers alongside standard forward-firing channels, producing a complete dome of three-dimensional sound matching commercial cinema standards.

The S95TR supports full Dolby Atmos and DTS:X decoding, passing 4K video signals transparently via integrated passthrough ports. Built-in WOWCAST establishes an uncompressed wireless link to compatible LG displays, eradicating audio latency without physical cords. Its Advanced Room Calibration system goes beyond basic frequency adjustments; utilizing internal microphones, it detects the precise spatial coordinates of the rear satellites within the room and corrects sound delays to maintain absolute temporal alignment across all nine horizontal and five height channels.

This package is built for discerning home theater enthusiasts with large entertainment areas who demand exhaustive spatial precision and multi-platform smart connectivity, including Apple AirPlay 2, Chromecast, and Google Assistant or Alexa support. Given its comprehensive physical scale and five distinct height channels, it requires adequate room clearance to permit clean acoustic reflections from the ceiling.

Best for: Large rooms needing expansive side soundstage coverage

The LG S90TR 7.1.3-Channel OLED evo TV provides an expansive acoustic profile designed to fill broad living rooms. Spanning 49.2 inches across its metal-constructed chassis, this soundbar integrates seven horizontal bed channels and three upward-firing height drivers, anchored by an active center height speaker for vocal articulation. A powerful wireless subwoofer and wireless rear surround speakers complete the discrete 7.1.3-channel array.

Engineered for high-end visual setups, the S90TR features built-in WOWCAST for wire-free Dolby Atmos and DTS:X signal transfer from supported displays. The Advanced Room Calibration system automatically measures acoustic delays and boundary reflections using built-in microphone hardware, rebalancing output across side-firing and surround channels. Immersive 3D Spatial Sound expands acoustic staging for films and gaming, while Hi-Res Audio compatibility maintains high dynamic range across music playback.

This model is optimal for open-concept floor plans and expansive seating arrangements where standard five-channel soundbars cannot provide complete side coverage. While offering broad dispersion and three height drivers at the front, its rear satellites lack the upward-firing height modules found on the S95TR, making the S90TR the choice for rooms with standard ceilings where rear height reflection is unnecessary.

Best for: Listeners wanting traditional surround sound with app tuning

Balancing multi-channel separation with straightforward control, the LG S6FTR 5.1 ch Home Theater delivers true discrete 5.1 surround sound. Measuring 33.5 inches in width, this shelf-mountable unit incorporates left, right, and center channels within the main bar, accompanied by a wireless subwoofer and dedicated rear surround speakers. The rear satellites establish a wireless link back to the main soundbar, though the listing notes that the two rear speakers connect to each other via an included wire, with one satellite connecting directly to AC wall power.

Acoustic processing is handled by Dolby Audio, enhanced by adaptive deep learning algorithms that analyze content types in real time to optimize vocal clarity during dialogue-heavy media and dynamic impact during action sequences. Unlike basic plug-and-play packages, the S6FTR provides detailed tonal management via the LG Soundbar App and LG ThinQ App, allowing users to customize equalizer settings across treble, midrange, and bass frequencies from a smartphone. The soundbar also integrates WOW Orchestra and WOW Interface for synchronized operation with compatible televisions.

The S6FTR is tailored for listeners who want dedicated 5.1 channel separation and detailed app-based equalization for standard living rooms. Because it lacks height channels and object-based Dolby Atmos decoding, it yields to the S80TR or S90TR for those seeking three-dimensional spatial overhead audio.
