LG Sound Suite: Dolby Atmos FlexConnect & TV Compatibility (2025 Models)

by Lisa Park - Tech Editor

LG is expanding the reach of its innovative Dolby Atmos FlexConnect technology, bringing a more flexible and immersive audio experience to a wider range of its OLED TVs. Initially showcased at , Dolby Atmos FlexConnect allows for a more adaptable home theater setup, and LG is now rolling out support to existing models via a software update.

Dolby Atmos FlexConnect: A New Approach to Immersive Sound

Dolby Atmos FlexConnect, at its core, aims to overcome a common challenge in home theater design: speaker placement. Traditional surround sound systems require precise speaker positioning to deliver the intended immersive effect. FlexConnect, however, allows speakers to be placed more freely within a room, with the system intelligently adjusting the audio output to compensate. This is achieved by leveraging the TV as a central hub, analyzing the audio signal and optimizing it for the specific speaker configuration and room acoustics.

Which LG TVs are Getting the Upgrade?

The software update enabling Dolby Atmos FlexConnect is being released for LG OLED G5, C5, and CS5 models. These TVs will now be able to directly connect to LG’s Sound Suite M5/M7 wireless speakers and the W7 subwoofer. This means users can build a Dolby Atmos system without the need for a traditional soundbar or complex wiring. The update effectively transforms these TVs into intelligent audio hubs, capable of delivering a customized immersive sound experience.

Beyond simply enabling compatibility, the update allows for a high degree of customization. LG states that users can create up to 22 different configurations by combining the M5/M7 speakers and the W7 subwoofer, tailoring the system to their specific room layout and preferences. This level of flexibility is a key differentiator for LG’s approach to immersive audio.

LG Sound Suite: More Than Just a Sound System

The Dolby Atmos FlexConnect integration is part of LG’s broader Sound Suite ecosystem. The Sound Suite, which garnered significant attention at , including 16 “Best of CES” awards, is designed to simplify home theater setup and provide a high-quality audio experience. Reviewers have highlighted its ability to address the often-difficult problem of speaker placement.

The M5 and M7 speakers within the Sound Suite also function as standalone Wi-Fi speakers, capable of 24-bit/96kHz lossless music playback. A dedicated “Heart Button” on the speakers provides instant access to Spotify, allowing them to operate independently of a TV or soundbar as a stereo setup. This dual functionality adds to the versatility of the system, making it suitable for both home theater and general music listening.

Beyond LG: The Expanding FlexConnect Ecosystem

While LG is currently leading the charge with Dolby Atmos FlexConnect, other manufacturers are beginning to explore the technology. TCL has announced its Z100 wireless speakers with FlexConnect compatibility, designed to work with its QM6K, QM7K, QM8K, and QM9K TVs. Hisense also demonstrated interest in FlexConnect at , though compatible products are not yet available in the US.

However, a key limitation currently exists: FlexConnect-enabled products from different manufacturers are not interoperable. This means that an LG TV will only work with LG’s compatible speakers, and a TCL TV will only work with TCL’s speakers. This walled-garden approach may limit consumer choice in the short term, but it could evolve as the technology matures and industry standards are established.

What Does This Mean for Consumers?

The rollout of Dolby Atmos FlexConnect represents a significant step forward in making immersive audio more accessible and user-friendly. By eliminating the constraints of traditional speaker placement, LG is empowering consumers to create a home theater experience that is tailored to their specific needs and preferences. The ability to expand the audio system over time, adding speakers as desired, also provides a cost-effective path to a more immersive soundscape.

For owners of LG OLED G5, C5, or CS5 TVs, the software update is a particularly welcome development, offering a substantial upgrade without requiring the purchase of new hardware. The combination of Dolby Atmos FlexConnect and the LG Sound Suite ecosystem positions LG as a leader in the evolving landscape of home audio.

The retail prices for the LG Sound Suite components are as follows: the H7 soundbar is priced at $1,000, the M5 speaker at $250, the M7 speaker at $400, and the W7 subwoofer at $600.
