Introducing the BRAVIA Theatre Sub 9: Ultimate bass. Ultimate power.

This 600W wireless subwoofer will move the air around you. From the faintest rumble to larger-than-life on-screen explosions, it delivers cinema-grade bass you can feel, without muddying dialogue.

With low frequencies you can usually only experience in the cinema, even the most subtle details are uncovered, immersing you deeper into every story.

Everything is clear and distortion-free, as our dual opposing drivers cancel out unwanted vibrations inside the cabinet. These 200mm drivers are made from premium materials for a tighter response and deliver an incredibly powerful total output of 600W from each unit.

Dual playback allows you to connect a second subwoofer for even bigger bass(1)(2)(3).

With a clean silhouette and refined finish, the BRAVIA Theatre Sub 9 is designed to fit seamlessly into your home. It even features a flexible design that can be placed in two different ways to suit your space.

It's ready to go straight out of the box, and our BRAVIA Connect app can be used for set up guidance and everyday control(4)(5).

Features

Sound Quality

The BRAVIA Theatre Sub 9 delivers premium bass, like you've never heard it before.

With low frequencies you can usually only experience in the cinema, this subwoofer unearths the low end layers that others leave behind. Think quiet, atmospheric rumbles to give every moment greater weight and deeper immersion.

The bass sound is always clear and undistorted, as our dual opposing drivers cancel out vibrations and unwanted noise inside the cabinet, to ensure tightly controlled bass with precise response. The effect is incredibly immersive, with deeper impact, natural silence, and a lifelike sense of space.

Powered by our large 200mm drivers with a total output of 600W from each unit, movie theatre-grade bass will roll through your living room, whilst keeping voices and textures crystal-clear. The BRAVIA Theatre Sub 9 fuses impact and precision into one supreme soundstage.

Expanded Sound System

Expand your sound even further, and let the BRAVIA Theatre Sub 9 be your catalyst.

With dual subwoofer playback, you can connect two subwoofers for an even stronger, more balanced low end(1)(2)(3). The increased sound pressure will fill your room with deep bass that's powerful, stable, and unmistakenly cinematic.

With a compatible BRAVIA TV, enjoy seamless integration as your entire BRAVIA home entertainment system can be controlled from a single remote; your sound settings will automatically appear on the TV's Quick Settings menu, so you can quickly and easily control your volume, and more(4).

In fact, you can build an entire BRAVIA Theatre using our matching soundbars, home theatre speakers, and AV amplifiers(5).

Bold, with a refined finish, the BRAVIA Theatre Sub 9 features a clean silhouette, with cable management to keep everything looking neat.
