X-Balanced Speaker Unit
Developed by Sony, the X-Balanced Speaker Unit achieves high sound quality and powerful sound pressure for a richer, deeper, more rewarding listening experience.
What is the X-Balanced Speaker Unit?
Unlike the circular diaphragm in a conventional speaker unit, the newly developed X-Balanced Speaker Unit in the XB33 features a non-circular diaphragm.
Increasing sound pressure and reducing distortion
The unit’s non-circular shape not only maximizes the area of speaker diaphragm, increasing sound pressure for more punchy bass—it also reduces driver excursion while maintaining the same sound pressure, resulting in less distortion.
Greater clarity and a wider sound stage
In addition, the unit’s off-centre design and optimised weight balance help to enhance clarity and widen the sound stage.
Mica Reinforced Cellular speaker cone and dust cap
The rigid and lightweight Mica Reinforced Cellular (MRC) speaker cone and dust cap contributes to the sound quality.
Side passive radiators
The layout of the side passive radiators has been optimised to reproduce clear bass sound.
