Overall, the LG S70TR shines for LG TV owners who want strong bass and clear sound. It may not be the top pick if you use a different TV brand though.
Channel Configuration and Audio Technology
The LG S70TR uses a 5.1.1 channel architecture that separates sound into distinct layers. You hear dialogue from the center, ambient effects from the sides, and action from behind you. The subwoofer handles low frequencies independently.
What makes this setup special is the up-firing center channel. Instead of sound traveling straight ahead, this speaker bounces audio off your ceiling. Your ears perceive sound coming from above, which creates genuine height perception. This is how Dolby Atmos works on this model.
The 9 total speakers work together to form a cohesive soundscape. The main bar contains the front channels. Two rear speakers connect wirelessly and sit behind your seating area. The subwoofer adds weight to explosions, music, and dramatic moments. The up-firing speaker adds the vertical dimension that standard soundbars cannot achieve.
3D spatial audio technology processes sound in real time. Your TV sends audio signals to the soundbar, which calculates where each sound should appear in your room. A car chase scene moves from left to right. Thunder rumbles overhead. Dialogue stays centered on screen.
The WOW Orchestra feature activates when you connect an LG QNED TV. This technology expands the soundstage beyond the physical width of the soundbar. Sound appears to come from points wider than the bar itself. Music feels more open. Movies feel more cinematic.
The wireless subwoofer and rear speakers eliminate cable clutter. You place them anywhere in your room without running wires. The system communicates wirelessly, so setup stays simple.
This channel configuration targets LG TV owners specifically. The technology integrates deeply with LG’s display systems. You get more features when both devices come from the same brand. Non LG TV owners still enjoy the soundbar, but they miss the ecosystem benefits.
The 5.1.1 layout sits between basic soundbars and premium cinema systems. You get height audio without needing a full surround setup with multiple overhead speakers.

Design, Build Quality, and Setup
The LG S70TR arrives in a sleek package designed to sit comfortably beneath your television. The Crest Design aesthetic uses clean lines and a minimalist profile. This shape means the soundbar won’t dominate your entertainment center visually.
Build quality feels solid throughout. The front panel combines plastic and metal accents for durability. The subwoofer uses a sturdy cabinet construction that handles the powerful bass output without vibration issues. Rear speakers feel lightweight yet well constructed for wall mounting or shelf placement.
Setup takes just a few minutes from unboxing to first sound. The wireless subwoofer connects automatically to the main bar once powered on. You don’t need to run cables across your room. Rear speakers pair wirelessly as well, which keeps your setup clean and flexible.
The included remote is intuitive with clearly labeled buttons. You can also control volume and input selection through your TV remote if it’s an LG model. The soundbar supports multiple connection methods including HDMI eARC, optical, and Bluetooth. This flexibility means you can connect older devices or newer ones without hassle.
Physical connections sit on the back panel in an organized layout. The HDMI eARC port handles both audio and video signals simultaneously. Optical input works great for devices that don’t support HDMI. Power management is straightforward with a single power cable and a standard outlet requirement.
The rear speaker setup deserves special attention. These 2 channel speakers mount easily on walls or shelves behind your seating area. They connect wirelessly to eliminate the messy cable runs that plague traditional surround setups. The mounting brackets include hardware for both drywall and other surfaces.
Overall installation requires no special tools or technical knowledge. Most people complete the full setup in under 10 minutes. The wireless connectivity removes the biggest headache from traditional home theater installation. If you own an LG QLED or QNED television, the integration process becomes even smoother with automatic optimization features.
Sound Performance and Spatial Audio
The LG S70TR soundbar delivers exceptional spatial audio performance that goes beyond standard stereo sound. Its 5.1.1 channel setup creates a layered listening experience where sound moves around you naturally. The up-firing center channel projects audio upward, adding height to your soundscape and making action sequences feel more immersive.
What sets this system apart is how it handles 3D spatial audio processing. Sound doesn’t just come from left and right. Instead, it flows from multiple directions simultaneously. Dialogue stays clear at the center while effects wrap around the room. Bass frequencies anchor everything with depth and weight.
The wireless subwoofer contributes significantly to spatial performance. Low frequencies extend the soundstage downward and outward. You feel explosions and music beats rather than just hearing them. The subwoofer operates independently, so you can position it anywhere in your room without running cables.
The rear speakers complete the spatial picture. They handle surround channels that make you aware of sound behind and beside you. Movies with ambient audio design shine here. Rain, wind, and crowd noise feel like they surround your seating area.
Connect this to an LG QNED TV and something special happens. The WOW Orchestra feature activates automatically. Your TV becomes part of the audio system. Sound appears to come from the screen itself, making on screen action feel more realistic and connected to the visuals.
The 9 total speakers work as one cohesive unit. Each speaker has a specific job. Together they create a soundstage that extends well beyond the physical bar. Voices remain centered and focused. Effects pan smoothly across the room. Music gains dimension and presence.
This soundbar handles all audio content well. Streaming shows benefit from the spatial enhancement. Gaming audio becomes more directional and responsive. Music tracks gain width and clarity. The system adapts to different content types automatically, adjusting how it distributes sound across its channels.

LG TV Integration and WOW Orchestra Feature
The LG S70TR truly shines when you pair it with an LG QNED TV. This integration unlocks features that standalone soundbars simply cannot match. The connection happens wirelessly, so setup remains straightforward.
WOW Orchestra is the star feature here. This technology expands your soundstage beyond the physical bar itself. When active, it creates an immersive bubble of sound around you. The effect feels like the audio wraps around your listening space rather than coming from one direction.
How does WOW Orchestra work? Your LG QNED TV communicates with the soundbar in real time. The system analyzes the content you’re watching and adjusts the sound field accordingly. Movies benefit most from this feature. Action sequences gain extra punch and width. Dialogue remains clear and centered where it belongs.
The up-firing center channel plays a crucial role in this integration. It bounces sound off your ceiling to create height and depth. Combined with WOW Orchestra, this creates genuine 3D audio that feels natural. You won’t hear obvious “phantom” speakers above you. Instead, the sound feels like it originates from the scene itself.
TV-specific optimization matters more than many people realize. The LG S70TR was built with QNED TVs in mind. This means the soundbar’s processing algorithms match perfectly with your television’s picture technology. The result is balanced audio that complements what you see on screen.
If you own a different TV brand, the soundbar still works well. However, you lose access to WOW Orchestra and its spatial enhancements. The core 5.1.1 performance remains solid across all TV types. But LG TV owners get that extra layer of immersion.
This ecosystem approach has trade-offs. You get superior performance with LG products. Yet you’re somewhat locked into the LG ecosystem for maximum benefits. For LG QNED TV owners, this is a feature, not a limitation. The integration justifies choosing this soundbar over universal alternatives.
Wireless Connectivity and Subwoofer Performance
The LG S70TR soundbar connects wirelessly to both its subwoofer and rear speakers. This wireless setup eliminates cable runs across your room, making installation cleaner and faster.
The subwoofer performance stands out as a key strength of this system. Deep bass frequencies hit with authority without overwhelming the mix. The subwoofer stays balanced with the main bar, so explosions and music don’t dominate dialogue. You get powerful low end that enhances movies and music equally.
Wireless connectivity between components works reliably in most home setups. The subwoofer pairs automatically during initial setup. You won’t need to manually configure connections or troubleshoot pairing issues. The rear speakers also connect wirelessly, maintaining that cable-free advantage throughout your listening space.
The subwoofer’s placement offers flexibility since cables aren’t a limiting factor. You can position it in corners, along walls, or wherever suits your room layout best. This freedom helps you optimize bass response for your specific space.
Subwoofer integration with the main bar happens seamlessly. The soundbar and subwoofer communicate constantly to deliver coordinated sound. Bass doesn’t feel disconnected from dialogue or effects. Instead, everything merges into one unified audio experience.
Performance remains solid across different content types. Movies benefit from the subwoofer’s impact during action scenes. Music tracks gain dimension from the added low frequency support. TV shows maintain clear dialogue while gaining atmospheric depth.
One consideration exists for non-LG TV owners. While the wireless subwoofer and rear speakers work with any TV brand, the system reaches its full potential with LG QNED models. The subwoofer still performs excellently regardless of your TV choice, but the ecosystem optimization matters less if you use a different brand.
The wireless subwoofer eliminates one major installation headache that plagues many home theater setups. No cables mean faster setup and greater placement options. The subwoofer performance justifies this wireless approach, delivering the bass quality you’d expect from a 5.1.1 configuration. Connectivity and subwoofer quality work together to make this system genuinely user-friendly while maintaining serious audio capability.
