Sony 7.1.4CH Home Theater with wireless subwoofer HT-A9-504W, Dolby Audio, Bletooth

A new frontier of surround sound

Feel sound from every direction and distance, even beyond the boundaries of your room. With our unique 360 Spatial Sound Mapping technology, the HT-A9 surround sound system immerses you, your family and friends in a multi-dimensional experience like never before.

360 Spatial Sound that adapts to your environment

Our revolutionary 360 Spatial Sound Mapping technology creates up to twelve phantom speakers from just four real speakers. 

360 Spatial Sound experience, like you are in the scene

Surrounded on all sides by multiple phantom speakers within an optimised 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

Experience ultra wide 360 Spatial Sound

An ultra wide listening area fills every part of your living space. Your family and friends get the same sound experience, wherever they are in the room. The listening area is not limited to the front of the TV but encompasses a much wider space.

Versatile layout for any kind of living room

No need to rearrange your furniture or precisely position your speakers. The HT-A9 uses dual microphones in each speaker to ingeniously measure their relative height and position, allowing the system to generate twelve phantom speakers and completely encircle your room in immersive spatial sound.

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 Theatre 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. 

Up-firing speaker (X-Balanced Speaker Unit)

This X-Balanced Speaker Unit reflects sound off the ceiling for immersive overhead audio.

Wide Directivity Woofer (X-Balanced Speaker Unit)

We have reduced the cavity effect of this new wide directivity X-Balanced woofer by minimising the depth of its concave shape.

X-Balanced Speaker Unit

The unique rectangular shape of these speakers maximises the diaphragm area for richer bass. It also reduces driver excursion while maintaining sound pressure, resulting in less distortion and greater vocal clarity. 

19mm Soft Dome Type Tweeter

This 19mm Soft Dome Type Tweeter works with the woofer to reproduce clear, natural sound at mid to high frequencies.

Bevelled baffle edges

The baffle has been designed with bevelled edges to reduce sound diffraction at the sides of the speaker.

High-Resolution Audio: 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 Audio for a truly immersive live concert or studio session experience. With the HT-A9 Home Theatre 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.

See vivid scenes full of real life colour and depth. All of the original picture quality is preserved when played through the HT-A9 Home Theatre System so you’ll be completely immersed in movies. Gaming is also much more thrilling and realistic as HT-A9 supports the latest formats.

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.
