Soundbar LG SC9S Black 3.1.3 channels 400 W

The LG SC9S soundbar is a 3.1.3-channel, 400 W system with a wireless 220 W active subwoofer, designed to deliver immersive home cinema audio. It is made to match LG OLED C series TVs (55/65/77” models from 2022 onward) and can be attached using the supplied bracket for a seamless visual integration. The SC9S supports Dolby Atmos, DTS:X and IMAX Enhanced and includes Triple Level Spatial Sound for expanded virtual surround coverage.

Advantages

The soundbar provides powerful, room-filling output and clear center-channel dialog through an up-firing center speaker. Triple AI Sound Optimiser features—Smart Up-Mixer, AI Room Calibration and AI Sound Pro—automatically adapt audio to the content and the listening environment. Native compatibility with recent LG TVs enables WOW Orchestra and WOW Interface functions for coordinated speaker use and simplified control via the TV remote and on-screen menus. Multiple wired and wireless connectivity options (HDMI with ARC/eARC support, optical, Wi‑Fi, Bluetooth, AirPlay, Spotify Connect) and 4K pass-through with VRR, ALLM and 120 Hz ensure broad device compatibility and high-quality video signal handling.

How to use

Attach the included bracket to the SC9S and mount it to a compatible LG OLED C series TV in either wall-mount or table-stand configuration for an integrated look. Connect the soundbar to your TV using HDMI ARC/eARC for best audio and control integration, or use optical or Bluetooth if HDMI is not available. Pair the wireless subwoofer to the soundbar following the user manual prompts. Use the LG TV remote or the soundbar controls to select sound modes; enable WOW Orchestra from the TV settings if both devices support it.

Recommendations

Place the soundbar centrally below the TV at ear level for optimal dialog clarity and surround effect. Allow a clear line of sight for the subwoofer and avoid enclosing it in a closed cabinet to maintain bass performance. Run the AI Room Calibration after installation to optimise sound for your room acoustics.
