Compatible Sony Soundbars and AV Receivers

The Sony SA-SW9 BRAVIA Theater Sub 9 wireless subwoofer is designed to expand compatible Sony soundbars and AV receivers with deep, low-frequency bass. It pairs with BRAVIA Theater Bar 9, Bar 8, Bar 7, HT-A7000, HT-A5000 and HT-A3000 soundbars. It also works with BRAVIA Theater Quad and STR-AN1000, STR-AZ1000ES, STR-AZ3000ES, STR-AZ5000ES and STR-AZ7000ES AV receivers.

Dual Subwoofer Capability and App Control

Connecting two Sub 9 units increases sound pressure for a stronger, more balanced low end that fills the room with cinematic bass. The BRAVIA Connect app handles setup and ongoing control, while a BRAVIA TV remote can adjust subwoofer settings directly without a separate handset.

Dual Opposing Aluminum Drivers

Dual opposing 7.9" aluminum drivers are arranged to cancel cabinet vibration and deliver clean, impactful bass. Wireless connectivity allows flexible placement without running cables across the room. This subwoofer is not suited for systems outside the listed Sony BRAVIA Theater and HT-A series or for users needing wired analogue inputs.

Questions about this item

Will the dual 7.9" aluminum drivers need periodic maintenance?

The sealed enclosure has no user-serviceable parts; the drivers are designed for the life of the product and require no scheduled maintenance.

What limits output first during a long movie marathon?

The built-in amplifier protects the dual 7.9" drivers by automatically reducing output if internal temperatures rise during sustained high-level playback.

How much fan noise or heat appears when the Sub 9 runs all day?

The unit uses passive cooling with no fan, so it adds no mechanical noise; the cabinet warms slightly but stays within normal operating limits for continuous use.
