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.

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.

Or discover a new way of listening with 360 Reality Audio1 for a truly immersive live concert or studio session experience.

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.
