Sony BRAVIA Theater Sub 9 Wireless Subwoofer

Bass like you’ve never felt before

With super-deep bass and ultra-low frequency response, this sub uncovers the low-end layers other systems leave behind. Powerful drivers deliver the rumbles, atmospheric tones, and seismic impact that give every moment greater weight and immersion.

Clean and undistorted

Dual opposing drivers cancel unwanted vibrations and noise inside the cabinet, delivering pure, tightly controlled bass with precise response—creating deeper impact, natural silence, and a lifelike sense of space.

Powerful bass. Stunning clarity.

Two 200 mm aluminum drivers deliver bass you can feel in your body. Clean, powerful sound that draws you into every scene.

Room-filling bass. Dual subwoofer playback.

Connect two subwoofers for a stronger, more balanced low end. The increased sound pressure fills the room with deep bass that’s powerful, stable, and unmistakably cinematic.¹

Harmonic Presence. Built for any space.

A bold form with a refined finish. The clean silhouette and hidden cabling keep the large presence sleek from every angle.

Do it all with BRAVIA Connect app

Easily control BRAVIA Theater from your smartphone. The BRAVIA Connect app guides you through initial setup and lets you adjust volume, sound field and more.²

Effortless Control with BRAVIA TV

Control bass easily with your BRAVIA TV remote. Sound settings automatically appear on the BRAVIA Quick Settings menu for easy access.
