Experience reverberating explosions and the deepest beats you've ever heard, without any distortion. In addition, you can enjoy authentic soundtracks with clearer voices and higher fidelity.Elegant omnidirectional design.The home entertainment system as well as the soundbar and optional speakers have been developed in a common omnidirectional block concept. The design of the SA-SW5 matches these systems perfectly. The cleverly rounded edges make it a single block with far-reaching sound. With state-of-the-art audio technologies such as the S-Magnetic Coil and Separated Notch Edge, the SA-SW5 provides powerful entertainment with deep, rich bass and clear low-frequency sound.S-Magnet Coil for deep, powerful bass Sony's S-Magnet Coil (Sigma) technology enables powerful bass by maximising the magnetic force that drives the voice coil. In contrast, conventional coils leave much of this magnetic force unutilised.Separated Notch Edge.Separated Notch Edge - another Sony technology - provides a clearer sound by improving the vertical symmetry of the vibration. This is achieved by central notches on the edge that control the tension of the diaphragm inside and outside it.Easy installation.The SA-SW5 automatically connects wirelessly to the home entertainment system or soundbar when switched on. This is quick and uncomplicated and requires no annoying cables.
