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. Built with dual opposing 200 mm aluminum cone drivers in a sealed enclosure, this wireless subwoofer produces deep, clean, tightly controlled bass with reduced vibration, helping movies, shows, sports, and music sound more immersive and more precise. 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.
