See the technology inside
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.
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.
