This home cinema system features an innovative Sony technology – magnetic fuid speakers.
Originally developed through the NASA space program, magnetic fluid is a liquid with magnetic properties.
Learn how the magnetic fluid speakers offer exceptional benefits in environmental performance.
In conventional speakers, dampers provide suspension for voice coils, which move up and down. For some time Sony had studied magnetic fluid as a viable means of suspension promising much better speaker efficiency. Finally in 2012, Sony R&D led to the first fluid suspension for mass-produced full-range speakers, enabling damperless speakers. Eliminating dampers can boost energy efficiency significantly, and Sony speakers with fluid suspension consume about 35% less energy than regular speakers, at a volume of 2 dB.

Fluid suspension also improves sound quality considerably. In conventional speakers, diaphragms are suspended on dampers which generate secondary sound pressure that may cause distortion. This sound pressure is not generated by a damperless, fluid suspension. Additionally, the pathway from the voice coil to the diaphragm can be shortened, which helps minimize transmission loss. As a result, these speakers offer clear, extended mids and highs.
