Sound worth sharing


Enjoy deep, punchy bass wherever you are with these latest wireless speakers. EXTRA BASSTM sound is achieved on the XB wireless speaker line up thanks to Sony’s renowned audio technology detailed below.

X-Balance Speaker Unit

Sony’s newly developed X-Balanced Speaker Unit achieves high sound quality and powerful sound pressure for a richer, deeper, and more rewarding listening experience. The unit’s non-circular shape maximizes the area of the speaker diaphragm, increasing sound pressure for more punchy bass. It also reduces driver excursion while maintaining the same sound pressure, resulting in less distortion. For example, the level of the sound pressure on the XB33 has increased by approx. 30% and the distortion rate is reduced by approx. 25% compared to the predecessor model (SRS-XB32). 

Unlike the circular diaphragm in a conventional speaker unit, the X-Balanced Speaker Unit in the XB43 features an almost rectangular diaphragm. Its 2-way speaker system combines a woofer for low to mid frequencies with a dedicated tweeter for the higher range frequencies. The result is a powerful sound, deep punchy bass, and exceptional vocal clarity.

The X-Balanced speaker unit in the XB33 and XB23 features a newly developed non-circular diaphragm and off-center design. This new design maximizes the speaker diaphragm, creating more sound pressure, but keeps the speakers compact in size.

Mica Reinforced cellular (MRC) cone and dust cap

The rigid and lightweight MRC cone and dust cap contributes to the sound quality.

Side Passive radiators

The layout of the side passive radiators has also been optimized across all three models to reproduce clear bass sound.
