The Sony BRAVIA Theatre Sub 9 is designed for listeners who want to add truly powerful bass to their home entertainment system. Whether you’re watching blockbuster films, enjoying live sports, gaming or listening to music, this wireless subwoofer adds the low-frequency impact that smaller speakers simply cannot reproduce.
Designed to work seamlessly with compatible Sony BRAVIA Theatre soundbars and home cinema systems, the Sub 9 delivers deeper, richer and more immersive sound without the inconvenience of running speaker cables across the room.
A great soundtrack is about more than volume. It’s about feeling the action as well as hearing it.
The BRAVIA Theatre Sub 9 is built to reproduce deep bass frequencies that bring movies and entertainment to life. Explosions feel more dramatic, orchestral soundtracks gain greater scale and sporting events become more immersive.
Whether you’re watching the latest action film or a tense drama, the added bass creates a more complete and engaging listening experience.
One of the biggest advantages of the BRAVIA Theatre Sub 9 is its wireless connectivity.
Instead of needing long speaker cables running around your living room, the subwoofer connects wirelessly with compatible Sony systems. This makes installation simpler and allows you to position the subwoofer where it performs best within your room.
For many households, this means a cleaner-looking setup without compromising sound quality.
If you’ve invested in a premium television or soundbar, adding a dedicated subwoofer can make a noticeable difference to overall performance.

Adding the BRAVIA Theatre Sub 9 can help create a more engaging gaming experience by reproducing deep bass effects such as engine sounds, explosions, environmental effects and cinematic cut-scenes.

The BRAVIA Theatre Sub 9 combines performance with a clean, understated design.
Its contemporary black finish blends naturally with modern televisions, soundbars and home cinema equipment, helping it fit comfortably into a variety of room styles.
Because the unit connects wirelessly, you also have more freedom to position it discreetly within the room.
The Sub 9 is designed to integrate seamlessly into compatible Sony BRAVIA Theatre systems.
