FEATURES

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.[FN|Sound Creators evaluated the combination of BRAVIA Theatre Trio + BRAVIA Theatre Rear 9 + BRAVIA Theatre Sub 9.]

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.[FN|]

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.[FN|Both pairing and dual subwoofer compatibility are required for your soundbar or home theatre system. Check the compatibility list. https://www.sony.co.jp/en/braviatheatre_2sub-models][FN|For dual subwoofer, subwoofers of the same model are required.]

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.

Built on the acoustics of professional studios


From the precision of professional studios comes 360 Spatial Sound Mapping. It transforms your space with cinema-quality audio, bringing every film closer to the way it was meant to be heard.

A cinema speaker layout at home


Phantom speakers are positioned based on a cinema speaker layout, creating a spacious surround field that captures the scale and immersion of the big screen.

Recreates cinema acoustics at home


By incorporating cinema-inspired acoustic design, 360 Spatial Sound Mapping not only simulates direct sound from speakers but also reproduces reflected, indirect sound—capturing the acoustic characteristics of a real cinema to recreate a dense, cinematic sound field.

Unleash the full potential of 360 Spatial Sound Mapping


Add optional wireless rear speakers for an even more expansive sound stage. Working with the rear speakers, BRAVIA Theatre Trio delivers even more immersive surround from behind you for that authentic movie theatre feel.

Sound straight from cinema


Bring authentic movie theatre surround sound quality to your living room. BRAVIA Theatre Trio not only supports industry-standard formats including Dolby Atmos® and DTS:X®, but also has IMAX® Enhanced certification.[FN|IMAX® Enhanced certification is achieved when used with compatible products. Product availability varies by countries/regions. https://www.sony.net/comp-home/]

IMAX® Enhanced sound by DTS:X


You can enjoy a truly cinematic experience with select Disney+ titles on BRAVIA and BRAVIA Theatre, powered by IMAX Enhanced technology.

Speaker placement made simple


Don’t worry about finding the perfect speaker position. Wherever you place them, Sound Field Optimization calibrates sound accordingly, using phantom speakers to create the ideal surround sound field.

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 our smartphone app, BRAVIA Connect, and BRAVIA Theatre Trio will detect your position in the room and optimise sound to suit.

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.

Hear sound from overhead


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.

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.

X-Balanced Speaker Unit


The speakers’ unique rectangular shape maximizes the diaphragm area for punchy bass. It also reduces driver excursion and maintains sound pressure, ensuring less distortion and greater vocal clarity.

Materials engineered for purer sound


An aluminium ring and copper cap are coupled with the lightweight driver cone to suppress harmonic distortion. Combined with the powerful magnet, you'll enjoy cleaner, more neutral sound across all frequencies.

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.

Wall-mounted or free-standing


Use them free-standing or wall-mounted—whichever fits your space.
