Boost your entertainment with mighty bass

Powering our Home Theatre System and soundbar with deeper bass, the SA-SW5 wireless subwoofer immerses you even further into movies and music. Feel how real entertainment becomes with clear, thumping bass and subtle low frequency sounds.


Deep, explosive bass

With 300W of deep bass sound from a powerful 180mm driver and passive radiator, this subwoofer boosts the impact of everything you watch and listen to. Enjoy booming explosions and the deepest beats you've ever heard 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-SW5 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.

With leading-edge audio technologies including Σ Magnetic Circuit and Separated Notch Edge, the SA-SW5 powers your entertainment with deep, rich bass and clear low frequency sound.

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.

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.
