Key Features:
Rich, deep bass
With 200W of deep bass sound from a powerful 160mm driver, this bass reflex subwoofer boosts the impact of everything you watch and listen to. Feel the deep rumble of thunder and heavy bass beats without distortion. You'll also hear clearer voices and extra fidelity for truly authentic soundtracks.
Omnidirectional Block Design
Our Home Theatre System, soundbar and optional speakers have been designed under a common Omnidirectional Block concept. The design of the SA-SW3 is a perfect match for these systems. Its sophisticated rounded edges represent a single solid block providing wide-spreading sound. The combination of rich material textures emphasises an affinity with any living room environment.
Σ Magnetic Circuit for deep, powerful bass
Sony’s proprietary technology, the Σ (Sigma) Magnetic Circuit enables deep, powerful bass by maximising the magnetic force that drives the voice coil. By contrast, conventionally shaped circuits let much of this magnetic force leak away.
Easy to set up
Simply power up the SA-SW5 subwoofer and it automatically makes a wireless connection with your Home Theatre System or soundbar. It’s quick and easy with no need for messy cables.
Separated Notch Edge
Another Sony proprietary technology, Separated Notch Edge improves vertical amplitude symmetry, an essential for clear sound quality. It achieves this using concentric cuts on the edge, which help to control the stress inside and outside the edge of the diaphragm.

Why Buy?
Deeper, richer bass for your Sony home theatre setup
If you already own a Sony soundbar or home theatre system, the SA-SW3 wireless subwoofer adds proper low-end weight to movies, music and games without a single extra cable across the room.
A dedicated bass driver and passive radiator work together to produce stronger, cleaner low frequencies, so explosions, drumbeats and rumbling engine noise land with more impact while dialogue stays clear on top. Sony's Σ Magnetic Circuit design squeezes more magnetic force into the voice coil, giving you deeper bass with less distortion, while the Separated Notch Edge technology keeps the diaphragm moving evenly for tighter, more controlled sound rather than a boomy, one-note thump.
Set-up is simple: switch it on and it pairs wirelessly with your compatible Sony soundbar or home theatre system, so you can place it wherever the room sounds best rather than wherever the cable reaches. Its rounded, textured Omnidirectional Block design matches Sony's current soundbar range, so it looks like it belongs rather than an add-on box hidden in the corner.
Buy this if…
- You already own a compatible Sony soundbar or home theatre system and want deeper bass
- You want wireless bass without running speaker cable across the living room
- You watch a lot of movies and want more impact from action scenes and soundtracks
- You want a subwoofer that visually matches your existing Sony setup
- You care about clean, controlled bass rather than a muddy, overpowering rumble
