360 Spatial Sound Mapping that adapts to your environment

Sony’s proprietary technology provides a much wider and immersive sound field. Sound Field Optimization calibrates the sound to your room for a listening environment that seems to expand beyond the walls.

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.

High-quality audio

The HT-A9 is equipped with Hi-Res Audio-capable X-Balanced speaker units to allow unparalleled bass reproduction with crystal clear highs. Dolby Atmos and DTS:X are supported, and the HT-A9 also has eARC to support high-quality audio from your favorite content providers.

Upscales Regular Audio

The Immersive Audio Enhancement button on the remote upscales regular stereo audio to close to 7.1.2 surround sound, adding a new dimension to your content.

Cutting-edge sound and visuals

Support for 8K, 4K/120p passthrough, and Dolby Vision brings vivid visuals and quality sound to shows, movies, and fast-paced video game play.

Easy Listening

It’s never been easier to listen to your favorite tracks. HT-A9 supports audio streaming via Bluetooth, Wi-Fi, Chromecast built-in, Spotify Connect, and Apple Airplay 2.

Customizable Ecosystem

Take your HT-A9 experience to the next level with Sony’s optional subwoofers. The SA-SW3 and the SA-SW5 subwoofers allow you to tailor how much extra bass you want to add to your setup. The subwoofers automatically pair to the HT-A9 for seamless and easy setup.

Easy UI

An OLED front panel display is also on the control box for quick viewing of the volume level, sound mode, or input. An on-screen user interface helps you make more detailed adjustments to your home theater system settings easily.
