Premium 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.

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.

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

Upgrade your sound with the perfect match. Whether it’s a soundbar, home theatre system, or AV amplifier, these options elevate your audio setup, delivering a richer, deeper experience.

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.

Easy bass boost with a direct TV connection

With a direct connection to a compatible BRAVIA TV, your subwoofer enhances bass without extra equipment. Simple setup, bigger sound.

Design

Deep bass, even in a 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.

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.
