The LG S70TY 3.1.1-Channel Soundbar is one of LG’s most thoughtfully designed audio systems to date — a perfect blend of elegant TV integration, Dolby Atmos immersion, and next-gen audio intelligence. Specifically engineered to complement LG’s QNED and OLED TV lineup, this soundbar takes cinematic sound to a new level with features like WOW Orchestra, AI Sound Pro, and a wireless subwoofer that adds powerful depth without clutter.
If you’re tired of flat, uninspired TV audio, the S70TY gives you a genuine theater-grade soundstage — clear dialogue, strong midrange, and expansive bass — all in a sleek form factor that blends seamlessly with your modern living space.
- LG QNED Matching – While a great sound enhancer for any LG TV, its smaller width and depth, allows it to nest perfectly beneath a stand mounted QNED TV. If wall mounted is your style, the soundbar is also fully compatible with the LG QNED Synergy Bracket, an easy-to-install soundbar shelf that attaches directly to the TV and not your wall.
Design & Build Quality
The LG S70TY is built to aesthetically and acoustically match LG’s QNED TV series. Its premium brushed-metal finish, minimalist edges, and slim profile make it look like an extension of your television rather than a separate accessory. Measuring under 3 inches tall, it fits neatly beneath most TVs without obstructing the screen or IR sensors.
The front metal grille conceals dedicated left, center, and right channels, while the up-firing driver handles vertical Dolby Atmos effects. The wireless subwoofer is compact yet powerful, providing a deep and resonant bass punch that enhances both action scenes and music playback.
Build quality is impressive — everything feels sturdy, refined, and designed with attention to detail. LG’s craftsmanship ensures long-term durability and consistent acoustic performance.
Audio Performance – Dolby Atmos That Truly Surrounds You
The highlight of the LG S70TY is its 3.1.1-channel Dolby Atmos configuration, which combines three front channels, one up-firing height channel, and a powerful subwoofer. Together, they deliver a cinematic 360° sound bubble that makes movies, music, and games come alive.
Thanks to Dolby Atmos and DTS:X decoding, sound moves fluidly around and above you, creating a realistic sense of depth and dimension. Whether it’s rain falling from above or cars racing from left to right, the audio positioning feels spatially accurate and engaging.
LG’s proprietary WOW Orchestra feature takes immersion even further by synchronizing the soundbar’s drivers with your compatible LG QNED TV’s built-in speakers. The result is a unified multi-speaker orchestra effect, expanding the soundstage vertically and horizontally without distortion.
For day-to-day use, AI Sound Pro automatically analyzes the type of content you’re watching — adjusting frequency balance and dynamic range for optimal results. Movies get deeper bass and cleaner dialogue, while news or talk shows sound crisp and natural.
With 420W of total power output, the S70TY fills medium to large rooms easily. Bass is tight and deep, mids are well-controlled, and treble is clear without harshness. It performs beautifully across all genres — from cinematic blockbusters to classical music to modern gaming sessions.
Smart Features & Connectivity
LG packed the S70TY with smart and flexible connectivity options to fit seamlessly into modern home setups:
- HDMI eARC for lossless audio transmission and simple control via your TV remote
- Optical input for legacy systems
- Bluetooth 5.1 for wireless streaming from smartphones, tablets, or laptops
- USB port for direct playback
- WOW Interface for one-touch sync with LG TVs
For LG TV owners, the WOW Orchestra and WOW Interface combination is a standout advantage. It allows easy control, unified sound optimization, and even on-screen soundbar settings through your TV menu.
You can also expand the soundstage by adding LG’s SPQ8-S rear speakers, transforming your setup into a 5.1.1 surround system for full Dolby Atmos immersion.
Real-World Performance & User Experience
In real-world testing, the S70TY delivers sound that feels effortlessly cinematic yet natural. Explosions, ambient effects, and music layers are well-separated. The center channel ensures dialogue remains crystal clear even in busy action scenes — something cheaper bars often struggle with.
The wireless subwoofer adds weight to low frequencies, yet stays balanced enough not to overpower the midrange. For gaming, especially when connected to an LG TV with Game Optimizer, the audio latency is impressively low, creating a highly responsive and immersive gaming experience.
Switching between sound modes is smooth and intuitive — AI Sound Pro often nails the balance automatically, but users who prefer manual tuning can adjust treble, bass, and channel balance to their liking.
Power consumption is low, and standby mode activates automatically, adding to energy efficiency.
