Sony BRAVIA Theatre Trio + SR Home Theatre System (HT-A8KIT)

Blockbuster sound—built for the biggest screens

Sony's flagship model, BRAVIA Theatre Trio, expands sound far beyond the screen. Perfect for today’s ultra-large TVs, its three-unit design and 360 Spatial Sound Mapping generate a vast, room-filling soundstage—bringing cinematic scale and immersion into your living room.

Cinematic sound, made for your home

Designed for today’s big screens, BRAVIA Theatre Trio’s three-unit system delivers wide, immersive sound. Through collaboration with Sony Pictures Entertainment, Sony are bringing home immersive sound, optimised for cinema content.

Three-unit system. One immersive experience.

Introducing a simple home theatre system that matches the scale of even the biggest screen. Left and right speakers wrap you completely in immersive sound, while a dedicated centre ensures dialogue is clear, making every scene feel cinematic.

Sound shaped with Sony Pictures Entertainment

Created in close collaboration with Sony Pictures Entertainment, this system brings studio-crafted sound into your home—capturing the emotion and detail intended by filmmakers.

Tuned with Sound Creators

Fine-tuned in collaboration with sound creators at Sony Pictures Entertainment, the BRAVIA Theatre Trio carries the same philosophy as professional film sound creators do. The result is a system that makes movies sound true to their creators’ intent.

Add more cinema. Dual subwoofer playback.

Connect two subwoofers for a stronger, more balanced low end. The increased sound pressure fills the room with deep bass that’s powerful, stable, and unmistakably cinematic.

Rewriting the rules of surround sound

By combining physical and phantom speakers, BRAVIA Theatre Trio creates a surround field that stretches wider than the screen, delivering cinematic immersion that pulls you into every scene.

Ultimate surround with 360 Spatial Sound Mapping

Experience the ultimate in home surround. 360 Spatial Sound Mapping technology creates up to 24 phantom speakers around the room, enabling cinema-style surround sound with just a handful of physical speakers.

Enjoy wider surround sound coverage

Now more people can enjoy the same immersive surround experience. By using phantom speakers, 360 Spatial Sound Mapping technology achieves wider coverage than conventional virtual surround systems.

Calibrated to suit your room

No need to remodel your home to get movie theatre acoustics. Sound Field Optimization analyzes your room’s acoustic characteristics, then uses advanced signal processing to overwrite them with those of a movie theatre.

Precise acoustic optimisation for your space

The included USB Type-C microphone connects to your mobile device to allow accurate automatic calibration that matches your room characteristics. A simple process during setup measures frequency, phase, and delay characteristics in your viewing space, to tailor the audio output to its unique acoustic requirements.

The best seat is where you are

Enjoy quality surround sound wherever you’re sitting. Just run calibration with the smartphone app, BRAVIA Connect, and BRAVIA Theatre Trio will detect your position in the room and optimise sound to suit.

Great surround starts with better acoustics

There’s more to great surround sound than signal processing alone. Your physical speakers need to deliver exceptional acoustic performance too—and BRAVIA Theatre Trio doesn’t disappoint.

Hear sound from overhead

Newly enlarged up-firing speakers reflect sound off the ceiling for immersive overhead audio. 360 Spatial Sound Mapping creates phantom ceiling speakers for even more atmospheric sound.

Powerful 2-way speakers

Front left and right speakers use a 2-way design with woofer and tweeter, delivering deep lows and crisp highs. The result is powerful, balanced sound that anchors your home cinema with clarity.

Enhanced centre clarity

The centre speaker features a new 2-way speaker with 2 woofers and a tweeter. With larger drivers, engineered for greater clarity and presence, dialogue stands out, while powerful sound fills your space with cinematic impact.

Fits your room, fills it like a theatre

Designed for any room, this system delivers cinematic sound wherever it’s placed. Flexible setup, uncompromised surround.

Clean, wireless cinema sound

Forget cluttered cables. With HDMI for the centre speaker and wireless links to the front left and right speakers, you get a streamlined setup that keeps your room tidy while filling it with surround sound.

Enhanced centre clarity

The centre speaker features a new 2-way speaker with 2 woofers and a tweeter. With larger drivers, engineered for greater clarity and presence, dialogue stands out, while powerful sound fills your space with cinematic impact.

So easy to use

BRAVIA Theatre Trio makes surround sound simple. From initial setup to smartphone control, it’s all about minimum effort, maximum enjoyment.

The BRAVIA Connect smartphone app guides you step by step, covering everything from connection to calibration and everyday control.

Bring the emotion and excitement of a movie theatre home. Pair BRAVIA Theatre Trio with a BRAVIA TV for an unmatched audio-visual experience, immersing you in every scene as never before.

Crystal clear voice. Precise dialogue.

No more muffled voices. Combined with compatible BRAVIA, the new Voice Zoom 3™ powered by AI machine learning recognizes human voices and amplifies or reduces their volume so even small dialogue sounds loud and clear.

Effortless control with BRAVIA

Control surround sound easily with your BRAVIA TV remote. Sound settings automatically appear on the BRAVIA Quick Settings menu for easy control of features, like Sound Field and volume.

One system, many ways to listen

From movies to playlists, BRAVIA Theatre Trio supports multiple sound modes—upmixing, multi stereo, and upconvert—so whatever you play is delivered with immersive audio that fills your room.

Upmix stereo content to surround sound

Sony’s upmixer delivers rich surround sound even from stereo content. Its innovative algorithm extracts and redistributes individual audio objects to immerse you in 3D sound. While upmixing, AI Sound Separation processing detects human voices and makes them sound clearer.

Amplify the moment with Multi Stereo

Multi Stereo enhances your listening experience by playing the same sound from both front (L/R/Center) and rear speakers, creating a full-room sound boost. Feel the sound reverberate with greater intensity, amplifying every moment.

Stream music from your favourite services

It’s not all about movies. You can also enjoy music in high-quality upmixed sound. Built-in support for Spotify Connect™ and Apple AirPlay lets you play all your favourite tracks.

Bluetooth® connection
