7.1.2 surround sound for home cinema
TCL Q85K soundbar offers immersive surround sound thanks to seven main channels, a wireless subwoofer, and two upward-firing channels. The audio wraps around you from all directions, creating a true cinema-like experience in your living room.

Three-way drivers for clean and balanced sound
TCL and Bang & Olufsen have co-selected premium materials for the three-way drivers dedicated to high, mid, and bass frequencies. Extensive listening tests and laboratory tuning are reflected in a design built to eliminate distortion and unwanted audio artefacts.
- Driver distortion under 1%
- Twice as smooth frequency response curve compared to industry standards
- Frequency response from 30 to 20000Hz

Independent amplifiers for precise audio processing
TCL Q85K uses a multi-channel audio architecture with independent control for each driver, spanning from the main board right down to the speaker units. A combination of a powerful System on Chip (SoC) and eight separate power amplifier chips ensures precise audio signal control, minimising distortion and compression during processing.

Subwoofer with dual-opposing drivers for deep bass
The custom design of the subwoofer features two opposing drivers that cancel out cabinet vibrations and resonance. Energy is distributed in both directions, ensuring rapid transient response and delivering deep, punchy bass. A sealed dual-opposing structure eliminates acoustic interference between the drivers, while a multi-density sound absorption system reduces internal reflections to maintain stable pressure inside the enclosure.

Wi-Fi 6 for lossless and wireless transmission
Powered by a wireless multichannel solution based on Wi-Fi 6, the system uses cutting-edge artificial intelligence processing power designed to eliminate distortion and compression during transmission with latency under 25ms. The subwoofer therefore communicates seamlessly with the soundbar.

Soundbar with acoustic tuning for natural sound
TCL Q85K soundbar builds on a thorough acoustic design and meticulous calibration aimed at delivering natural sound with plenty of detail.
- Custom acoustic solution – supports a balanced soundstage and surround listening throughout the room
- Co-designed hardware – optimises acoustic pressure in a compact design and contributes to a clean, dynamic performance
- Tuning in the Cube electroacoustic chamber – helps verify sound properties during laboratory measurements
- Proprietary tuning technology – highlights subtle nuances and preserves rich audio details

Surround sound with an expanded soundstage
The System on a Chip (SoC) combined with independent amplifier chips also creates side surround sound effects. Optimising sound routing helps expand the soundstage and sharpens the perception of where individual sounds are coming from. The result is a wider spatial impression when watching movies and playing games.

3D audio upmixing
Activate surround mode with a single tap. The audio upmixing algorithm developed by TCL converts a standard two-channel 2.0 input into a 7.1.2 output format, expanding the spatial impression even for content not originally created for multichannel playback.

Sound calibration via the TCL mobile app
Download the TCL mobile app and connect it to your soundbar to access additional audio setup features. The system scans the acoustic profile of the room and adjusts the playback accordingly to match the layout of the space and the position of the listeners.
- Customisation of the ideal listening position
- Sound optimisation using adaptive calibration
- Space scanning
- Eight sound modes for various situations, including movies, games, and sports

TCL Q85K soundbar – Elegant design and flexible placement
The design of the soundbar draws inspiration from natural valleys. A floating base helps reduce the transmission of vibrations and unwanted resonance. The solid frame is complemented by an acoustic mesh that protects the internal components from dust. Materials are also used in production. The seamless grille undergoes 13 bending processes, which the manufacturer claims contribute to up to 15% greater strength. A five-sided sound output helps widen the soundstage. The ultra-slim design allows for both stand placement and wall mounting, with the soundbar height being just 6.87cm. When you change the installation method, the system automatically adjusts the sound projection and EQ settings.

Synchronise TV and soundbar with Tutti Choral
When you connect the soundbar to a compatible TCL TV, you can use Tutti Choral technology to play audio from both devices together. The system optimises and distributes audio signals so that the TV and soundbar play in perfect sync. This results in a wider soundstage, more balanced surround sound, and audio that is perfectly in sync with the picture. Feature availability depends on the specific TV model.
