Compact size

The SRS-XB23 fits perfectly in the cupholder of your camping chair – great for chilling out at open-air festivals.

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 XB23 features a non-circular diaphragm.

The unit’s non-circular shape not only maximises 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.

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.

Dustproof, waterproof and washable

With an IP67 rating, you can take your speaker to the beach, the forest, the desert – the SRS-XB23 will keep on playing, no matter how dusty the surface. It’s waterproof and salt water resistant too – no worries by the sea or the pool – and there’s no problem washing it either.

Built to last

The SRS-XB23 has undergone extensive shock testing to make sure it can withstand the inevitable knocks, bumps and scrapes that come with everyday use.
