Sony Bravia Theatre Sub 9 Wireless Subwoofer (SA-SW9)

Deeper bass. Every cinematic detail.

Impact with finesse. Dive deep into ultra-low frequencies, uncovering bass that makes rooms tremble and moments resonate. Dual opposing drivers reduce distortion, while 600 W of power and large 200 mm units deliver deep, pure, and commanding bass

Bass like you've never felt before

With ultra-low frequency response, this subwoofer uncovers the low-end layers other systems leave behind. Quiet rumbles and atmospheric tones give every moment greater weight and immersion.

Sony BRAVIA Theatre Sub 9

Clean, undistorted bass

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.

Sony BRAVIA Theatre Sub 9

Powerful bass. Stunning clarity.

Two 200 mm aluminum drivers, 300 W each—600 W total—deliver bass you can feel in your body. Clean, powerful sound that draws you into every scene.

Boost your bass: Find your perfect match

Take your sound further by adding a subwoofer. Paired with a soundbar, a home cinema setup, or a compatible BRAVIA TV, it delivers more depth, more power, and a richer listening experience.

Sony BRAVIA Theatre Sub 9

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.

Sony BRAVIA Theatre Sub 9

Deep bass, even in limited space

Your room layout, your choice. Front-facing for open placement, or slits forward when space is tight. Rich bass adapts to your space.
