LG challenges Sonos. The first Dolby Atmos FlexConnect audio system debuts!

Calendar 12/18/2025

LG Sound Suite is a new wireless audio system with Dolby Atmos FlexConnect, allowing soundbars and speakers to connect without cables and enabling the creation of a home theater setup with up to a 13.1.7 configuration.

LG is entering the game in the premium wireless audio segment. At CES 2026, the company showcased LG Sound Suite, its first ecosystem of speakers based on Dolby Atmos FlexConnect technology. This solution aims to combine the flexibility known from Sonos with full-fledged Dolby Atmos spatial sound – without cables and without the classic amplifier tangle.

What is Dolby Atmos FlexConnect

Dolby Atmos FlexConnect is a new audio platform where speakers connect wirelessly directly to the television or soundbar, and the system automatically calibrates itself to the room conditions. Thanks to active acoustic correction, speakers do not have to be in “ideal” locations – they can be on shelves, in corners, or behind the sofa.

As Dolby emphasises, it’s about maximum freedom of configuration without compromising sound quality. This element is expected to pose the greatest threat to Sonos, which has dominated the modular audio systems segment for years.

LG Sound Suite – system components

The new LG Sound Suite ecosystem consists of several components that can be combined in various configurations:

  • LG H7 – 3.1.2 soundbar with upward and side-firing speakers, the first soundbar on the market with Dolby Atmos FlexConnect

  • LG M5 – compact 2.1.2 speakers

  • LG M7 – larger 4.1.2 speakers

  • LG W7 – 8” subwoofer that can stand vertically or lie flat, with a claimed frequency response down to 25.9 Hz

All transducers are supplied by the Danish company Peerless Audio, and the H7 soundbar is powered by the Alpha 11 Gen 3 processor, known from LG's OLED TVs for 2026.

Soundbar is not mandatory

One of the more interesting elements of FlexConnect is that the soundbar is not always necessary. LG demonstrates configurations where four M7 speakers serve as front and rear channels, connecting directly to the LG TV from 2026. This approach is quite similar to Sony's Theatre Quad concept – only without a cable to the central unit.

Alternatively, the system can be built in a classic way: the H7 soundbar as the centre, along with M5 or M7 speakers as satellites and the W7 subwoofer. Importantly, the system can be expanded over time, just like in the Sonos ecosystem.

Up to 13.1.7 Dolby Atmos channels

LG declares that a configuration of up to 13.1.7 is currently possible, which means:

  • 13 channels at ear level

  • 1 subwoofer

  • 7 height channels

In practice, the system supports:

  • up to 4 wireless speakers

  • 1 subwoofer

  • direct connection to the TV or soundbar

Initially, 27 different configurations are available, and LG emphasises that this is more than what ChooseTV offers – especially in terms of speaker placement flexibility.

Limitations – like Sonos

Not everything looks perfect, however. Mixing speakers from different brands is still not possible, despite earlier suggestions during the first announcements of FlexConnect in 2023. In practice, this means a closed ecosystem – exactly like with Sonos.

A certain question mark remains over signal delay. Dolby admits that FlexConnect introduces latency, which can be compensated for when watching movies and series. LG has not yet confirmed whether the system will be fully usable for gaming on consoles in 2026.

Support for LG TVs

Dolby Atmos FlexConnect will be natively available on selected LG TVs from 2026, and the update will also be provided for models from 2025:

  • G5

  • C5

  • C5S

  • QNED9M

Sound Suite also supports music features, including AirPlay, Google Cast, and Spotify Connect, allowing it to function as a full-fledged audio system for music.

When and for how much

The market launch of the LG Sound Suite is scheduled for 2026. Prices have not been disclosed yet, but everything indicates that LG is targeting the premium segment – directly where Sonos has reigned for years. One thing is certain: Dolby Atmos FlexConnect is finally coming to a big player, and LG could be the first company to realistically threaten Sonos's dominance in the world of wireless home cinema.
