Overview

The LG S75Q is a 3.1.2-channel soundbar system that brings Dolby Atmos and DTS:X surround sound into your living room without the complexity of a full speaker setup. With dedicated up-firing drivers that bounce sound off your ceiling, it creates a convincing sense of overhead audio that pulls you into movies, shows, and games. The partnership with Meridian Audio — a British company known for high-end audio engineering — ensures that the sound profile is refined and balanced, with particular attention paid to vocal clarity through the dedicated center channel.

Connectivity is handled through HDMI eARC, which supports the highest quality audio formats, along with 4K Pass-Thru with Dolby Vision so your picture quality isn't compromised. Bluetooth is available for streaming music directly from your phone or tablet. For LG TV owners, the S75Q offers standout integration: the Synergy TV mode lets your TV's sound engine work in concert with the soundbar, and you can manage everything from a single remote. The included wireless subwoofer with its 7.1-inch driver handles bass duties effectively, rounding out the system. At 35.1 inches wide and just 2.6 inches tall, the soundbar maintains a low profile that fits neatly under most TVs, and LG's use of recycled materials in construction and packaging adds an environmentally conscious touch.
