See the technology inside With leading-edge audio technologies including Σ Magnetic Circuit and Separated Notch Edge, the Sony SA-SW5 powers your entertainment with deep, rich bass and clear low frequency sound. Σ Magnetic Circuit for deep, powerful bass Sony SA-SW5 proprietary technology, the Σ (Sigma) Magnetic Circuit enables deep, powerful bass by maximizing 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. Easy to set up Simply power up the Sony 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.
