See what experts at Sony Pictures think of our 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.

Connect wirelessly

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

Our speakers are designed with leading-edge technologies to deliver the supreme sound quality and wide directivity required for 360 Spatial Sound Mapping.

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 8K, 4K/1203 passthrough, and Dolby Vision 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.

Perfect with Sony TVs

Paired with BRAVIATM TVs, the HT-A7000 brings you an immersive audio-visual experience with our best picture and sound quality. It’s the perfect soundbar for BRAVIA.

Even more immersion with Acoustic Center Sync

When connected with the supplied cable to a BRAVIA TVs, the TV speaker plays the center channel role in your Home Theater System and part of the 360 Spatial Sound Mapping setup.4 This enables sound to precisely match what’s on the screen for a truly immersive experience.

Sound perfectly matches action

With Acoustic Center Sync, you’ll hear dialogue from exactly where the character is standing in the scene. Action and sound are precisely aligned so your viewing becomes much more immersive.

Effortless control with BRAVIA TVs

Everything links up perfectly when connected to the new range of BRAVIA XR™ TVs. Control sound settings and volume using only the TV remote and easily check the status of the audio system while watching favorite programs. With an integrated UI, Home Theater System settings automatically appear on the BRAVIA TVs Quick Setting menu.

Omnidirectional Block Design

The HT-A9 is one of our latest home sound systems, designed using the Omnidirectional Block concept. The cylindrical shape represents a single solid block providing 360 spatial sound. It fits perfectly against the wall with a flat rear surface. The light pearl grey color blends well with walls, shelves and other interior elements.
