X-Balanced Speaker UnitX-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 Sony XB43 features an almost rectangular diaphragm.

The Sony XB43’s 2-way speaker system combines a woofer for low to mid-range frequencies with a dedicated tweeter for the higher range frequencies. The result is exceptional vocal clarity.






Mica Reinforced Cellular speaker cone and dust cap

The rigid and lightweight Mica Reinforced Cellular (MRC) speaker cone and dust cap contribute to the sound quality.




Side passive radiators

The layout of the side passive radiators has been optimised to reproduce clear bass sound.

There’s no fun without party lights. The SRS-XB43 has a tweeter light, a speaker light, and a multi-colour line light that all flash in sync with the beat. You can even change the colour of the line light to suit your mood.
