A new frontier of surround sound
Immerse yourself in a multi-dimensional audio experience with the HT-A9 Home Theater System. Unique 360 Spatial Sound Mapping technology calibrates sound to your room for an environment that seems to expand beyond the walls.
360 Spatial Sound that adapts to your environment
Sony's revolutionary 360 Spatial Sound Mapping technology creates up to twelve phantom speakers from just four real speakers. Here's how.
See what experts at Sony Pictures think of Sony's new sound
In this video, two sound professionals from Sony Pictures Post Production Services talk about their experience with the HT-A9 and how 360 Spatial Sound Mapping brings movies to life.
360 Spatial Sound experience, like you are in the scene
Surrounded on all sides by multiple phantom speakers within an optimized sound field, you’ll hear every flap of wing and gust of wind with incredible intensity. It’s like you and your living room are inside the movie.
Flexible layout for any situation
Reduce clutter and enjoy a simple setup without a need for extra cables. HT-A9’s speakers wirelessly connect to the control box, allowing you to place them anywhere in the room. Sound Field Optimization allows you to have the speakers at different heights and distances and will measure the position of each speaker to create the best sound for your room.
Place the control box near the TV and link up via HDMI. The four speakers connect wirelessly to the control box so there’s no cables across your living space.
Sound Field Optimization
Activate Sound Field Optimization any time by performing Easy Setup from the home menu on the TV screen. The HT-A9 Home Theater System intelligently measures the distance between speakers and ceiling for smart and easy set up.
Innovative speaker design
Sony's speakers are designed with leading-edge technologies to deliver the supreme sound quality and wide directivity required for 360 Spatial Sound Mapping.
- Up-firing speaker (X-Balanced Speaker Unit)
- Soft Dome Type Tweeter
- Wide Directivity Woofer (X-Balanced Speaker Unit)
- Dual microphones
X-Balanced Speaker Unit
The unique rectangular shape of these speakers maximizes the diaphragm area for richer bass. It also reduces driver excursion while maintaining sound pressure, resulting in less distortion and greater vocal clarity.
Movies and games feel so real
Support for 8K2, 4K/1203 passthrough, and Dolby Vision7 brings vivid visuals and quality sound to shows, movies, and fast paced video game play.
Immerse yourself in supreme music quality
Enjoy music the way the artists truly intended with High-Resolution Audio for crystal clear precision. Or discover a new way of listening with 360 Reality Audio1 for a truly immersive live concert or studio session experience. With the HT-A9 Home Theater System, your music comes to life like never before.
Real-time restoration of all your compressed files
Using Edge-AI (Artificial Intelligence), DSEE Extreme™ (Digital Sound Enhancement Engine) upscales compressed digital music files in real time. Dynamically recognising instrumentation, musical genres, and individual elements of each song, such as vocals or interludes, it restores the high-range sound lost in compression for a richer, more complete listening experience.
Hear extra deep bass with an optional subwoofer
Adding an optional subwoofer to your system to handle low frequencies allows the system to reproduce sounds with greater impact and power than before. Two models are available, designed to bring out deeper bass, more voice clarity and extra fidelity in everything you listen to.
