Sony BRAVIA Theatre Sub 9 SA-SW9 Wireless Subwoofer, Black

The Sony BRAVIA Theatre Sub 9 600 W Wireless Subwoofer is an active subwoofer for compatible home theatre and soundbar systems. Its 600 W RMS rating refers to the audio output power, not the electrical consumption. The unit adds low-frequency sound to films and music through a wireless connection to a compatible system, so compatibility with the intended Sony home entertainment system is an important consideration before purchase. This is a separate bass speaker, not a standalone soundbar or a complete home theatre package.

Two opposing 200 mm drivers handle the bass output. Their aluminium cones are paired with a vibration-dampening design intended to keep the sound controlled. Setup is carried out using the BRAVIA Connect app, which provides a phone-based route for configuring the subwoofer. Smartphone and tablet remote support is also listed, allowing control from a mobile device. Despite its wireless audio connection, the subwoofer uses AC power and still requires access to a mains outlet.

• 100 W specified power consumption distinguishes electrical demand from the audio output rating.
• 23.3 kg weight is worth considering when positioning or moving the unit.
• Black finish provides a neutral appearance alongside other home cinema equipment.
• No remote control is included.
• AC power cord, user guide, and quick start guide are supplied.
