The LG S90TR 7.1.3-Channel Soundbar represents the pinnacle of LG’s 2024–2025 home theater lineup — a flagship Dolby Atmos sound system that delivers truly cinematic immersion with refined design and intelligent integration. Built to match LG OLED evo and QNED TVs, it combines WOW Orchestra, WOWCAST built-in wireless connectivity, and triple up-firing Atmos channels to fill every corner of your room with dimensional sound.
This soundbar isn’t just powerful — it’s smart, future-ready, and stunningly balanced. Whether you’re watching 4K HDR blockbusters, gaming in Dolby Atmos, or streaming lossless music, the S90TR transforms your living room into a next-gen theater experience.
- Cinema Sound Solution – Take your home theater sound to a new level with this high-performance 7.1.3-channel soundbar powered by Dolby Atmos and DTS:X technologies.
- Rear Speakers – Our new rear surround speakers have wireless connectivity—no special receiver needed to deliver an immersive audio experience.
Design & Build Quality
The LG S90TR features a premium brushed aluminum finish that pairs perfectly with OLED evo TVs. Its sleek edges, ultra-slim profile, and clean symmetry make it both functional and stylish. Despite housing 11 total speakers (7.1.3 setup), the bar remains surprisingly elegant and low-profile.
You get dual wireless rear surround speakers and a powerful 220W wireless subwoofer included, making this a complete package straight out of the box. The rear speakers support up-firing channels, providing height effects from behind — creating a seamless 360° Dolby Atmos dome that engulfs you from every direction.
Build quality is exceptional — every component feels solid and meticulously engineered. Even the subwoofer enclosure is acoustically tuned to minimize distortion while maximizing low-frequency punch.
Sound Performance – Pure Dolby Atmos Mastery
The S90TR’s 7.1.3-channel system delivers a total output of 620 watts, powered by LG’s advanced digital amplifier. With three up-firing channels, two rear up-firing drivers, and a dedicated center channel, this soundbar delivers true 3D audio rather than simulated effects.
The result?
- Dolby Atmos and DTS:X tracks explode with life, depth, and spatial precision.
- Helicopters soar above, rain pours from overhead, and whispers stay locked to the screen with pinpoint dialogue clarity.
- The wireless subwoofer adds chest-thumping bass that’s both deep and controlled — perfect for action movies or EDM music.
The WOW Orchestra feature syncs the soundbar with your LG TV’s internal speakers to create an even wider, more dynamic soundstage. It feels as though your TV becomes part of the sound system — amplifying mids and highs while maintaining deep cinematic bass.
Meanwhile, AI Sound Pro continuously analyzes what you’re watching, automatically optimizing EQ and channel balance in real time. Dialogue becomes sharper, explosions more detailed, and ambient effects more lifelike.
Even at max volume, distortion is nearly nonexistent — a testament to LG’s refined digital signal processing.
Smart Features & Connectivity
The WOWCAST built-in feature is a game changer — allowing you to connect the soundbar wirelessly to compatible LG TVs with no loss in quality. This means you can enjoy uncompressed Dolby Atmos and DTS:X audio without HDMI cables cluttering your setup.
Connectivity highlights:
- HDMI eARC for high-resolution passthrough
- Optical and USB inputs
- Bluetooth 5.1 and Wi-Fi streaming
- Works with WOW Interface, letting you control all sound settings via your LG TV’s on-screen menu
The S90TR also supports Hi-Res Audio (24-bit/96kHz) playback and is compatible with Meridian Horizon upmixing technology, ensuring that even stereo sources sound immersive and detailed.
For audiophiles and gamers, it supports 4K HDR10 passthrough, VRR, and ALLM for low-latency gaming setups.
Real-World Experience
In real-world testing, the LG S90TR feels like a mini IMAX system. Movies like Top Gun: Maverick or Dune showcase breathtaking realism — jets whoosh overhead, bass rumbles your chest, and dialogue stays anchored dead-center.
The rear speakers make a massive difference compared to standard 5.1 setups, especially in large or acoustically reflective rooms. When paired with an LG OLED evo display, the synergy between picture and sound is phenomenal.
The system also excels for music listening — AI Sound Pro adapts to genre, giving vocals richness and instruments clarity. Gaming performance is top-tier, with directional accuracy that adds an edge to competitive shooters.
Setup is fast and wireless. The WOWCAST feature automatically connects the bar to the TV once powered on, while the LG Sound Bar app provides granular EQ control, firmware updates, and calibration tools.
