XB43 EXTRA BASS™ Portable BLUETOOTH® Speaker

Enjoy powerful sound anywhere

Enjoy deep, punchy sound wherever you like with your EXTRA BASS™ speaker. Dual passive radiators work together with the 2-way speaker system to enhance low-end tones, giving bass a boost. 

X-Balanced Speaker Unit enhances sound quality and power

Developed by Sony, the X-Balanced Speaker Unit achieves high sound quality and powerful sound pressure for a richer, deeper, more rewarding listening experience.

How the X-Balanced Speaker Unit works

Unlike the circular diaphragm in a conventional speaker unit, the newly developed X-Balanced Speaker Unit in the XB43 features an almost rectangular diaphragm. This 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 and greater vocal clarity.

Tweeter improves vocal clarity

The 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.

Hear it like it’s live

Hit the LIVE SOUND button and hear your music in a whole new way. Bring your party to life with a unique three-dimensional sound experience – creating festival vibes wherever you go.

How LIVE SOUND mode works

The speakers of the SRS-XB43 are carefully designed to give you a real three-dimensional experience. Our angled speakers with DSP technology send your music to a wider area, creating a festival vibe, wherever you are.

Totally dustproof

Thanks to the IP67 rating, you can take your speaker to the beach, the forest, the desert, or wherever you like – the SRS-XB43 will keep on playing, no matter how dusty the surface.

Totally washable and waterproof

With an IP67 rating, your speaker is waterproof and salt water resistant – so you’ve no worries using it by the sea or the pool – and there’s no problem washing it either. 

Long battery life

Up to 24 hours of battery life means the SRS-XB43 can party even longer than you can. Even with the lighting on in EXTRA BASS™ mode, you can party for up to 14 hours.

Light up the party

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.
