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.

Sound

The SRS-XB43 has been engineered to deliver an irresistible blend of deep, resonant bass and clear, natural vocals.

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 XB43 features an almost rectangular diaphragm.

What does it do?

The unit's rectangular 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 and greater vocal clarity.

Maximising sound quality

The X-Balanced Speaker Unit isn't the only reason the SRS-XB43 sounds so good - inside, you'll find a range of high-performance audio technologies.

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.
