With 200 W of deep bass sound from a powerful 160 mm 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.

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.

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.

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.
