Sony BRAVIA Theater Sub 9 Wireless Subwoofer

Sony BRAVIA Theater Sub 9 Wireless Subwoofer delivers premium, room-shaking bass designed to reveal the ultra-low frequencies that standard audio systems often miss.

Its wireless design keeps setup cleaner and more flexible, while compatibility with select Sony BRAVIA Theater soundbars, home theater systems, and AV receivers makes it an easy upgrade for a more cinematic listening experience. For users who want even greater low-end impact, compatible systems can support two matching Sub 9 units for stronger, more balanced bass throughout the room.
