Overview

The LG S70TY is a 3.1.1 channel soundbar system that pairs a slim, wall-mountable bar with a wireless subwoofer to deliver Dolby Atmos spatial audio. Its standout engineering detail is the up-firing center channel — a dedicated driver angled upward to bounce sound off the ceiling and create a heightened sense of vertical dimension in the soundstage. This center channel also handles dialogue duties, which means voices are projected with noticeably more clarity and presence than soundbars that rely on left-right drivers alone. The result is a system that handles both explosive action sequences and quiet conversational scenes with equal composure.

Where the S70TY truly distinguishes itself is in its LG ecosystem integration. WOW Orchestra synchronizes the soundbar's speakers with your LG TV's built-in speakers, creating a larger combined soundstage that neither device could achieve independently. WOW Interface consolidates all audio controls onto the TV remote, eliminating the need to juggle multiple remotes. The metal-grilled crest design is both visually refined and functionally practical, keeping dust out of the drivers. For gamers, HDMI passthrough supports up to 120Hz with VRR and ALLM, ensuring audio processing doesn't introduce lag. The system also supports Hi-Res Audio and includes a Smart Up-Mixer that converts standard 2-channel content into a multi-channel experience, making everyday streaming and music listening sound more expansive.
