LG US77TY 3.1.3 Soundbar 400W with Wireless Subwoofer

Bring cinematic sound into your living room or gaming setup with the LG US77TY 3.1.3 wireless soundbar, designed for users who want powerful, immersive audio without the complexity of a full speaker system. Perfect for movies, console gaming and streaming, this system transforms everyday entertainment into a front-row experience with rich, detailed and room-filling sound.

At the core of the system is a 3.1.3 channel layout with 9 integrated speakers, including up-firing drivers that project sound vertically to create a true Dolby Atmos and DTS:X surround effect. This helps place audio all around you, delivering height, depth and direction that enhances both cinematic scenes and competitive gaming environments.

A powerful 400W total output ensures the sound remains bold and dynamic, while the wireless subwoofer delivers deep, controlled bass that adds impact to explosions, music and low-frequency effects. Whether you're watching films or gaming on a next-gen console, the system is tuned to deliver a more engaging and immersive experience.

AI Sound Pro automatically analyses content in real time and adjusts audio settings to maintain clarity, balance and detail. This means dialogue stays crisp, background effects remain controlled, and action scenes feel more dynamic without manual adjustments. Multiple sound modes including Cinema, Game, Music and Clear Voice Pro allow further customisation depending on your setup and content type.

Designed for modern entertainment systems, the LG US77TY supports 4K pass-through with Dolby Vision, VRR and ALLM, making it an excellent companion for gaming consoles and high-definition streaming devices. Bluetooth connectivity also allows quick and easy wireless streaming from phones, tablets or laptops.

With LG’s WOW Orchestra feature, compatible LG TVs can combine their built-in speakers with the soundbar for a wider, more powerful soundstage. This creates a more cohesive and immersive audio environment without additional hardware or complicated setup.

Ideal for home cinema setups, gaming rooms and entertainment spaces, this LG soundbar delivers premium surround sound performance in a streamlined, easy-to-use design.
