The SRS-XB43 wireless speaker blends deep, punchy bass with clear vocals for that signature festival sound. It's durable and easy to use, too, so you and your friends can focus on enjoying the party.
Explore some of the features and technologies that make the SRS-XB43 so special.
Enjoy deep, punchy sound wherever you like with your EXTRA BASS speaker. Dual passive radiators work together with the two-way speaker system to enhance low-end tones, giving bass a boost.
The SRS-XB43 has been engineered to deliver an irresistible blend of deep, resonant bass and clear, natural vocals.
Developed by Sony, the X-Balanced Speaker Unit achieves high sound quality and powerful sound pressure for a richer, deeper, more rewarding listening experience.
Unlike the circular diaphragm in a conventional speaker unit, the newly developed X-Balanced Speaker Unit in the XB43 features an almost rectangular diaphragm.
The unit's rectangular shape not only maximizes 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.
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.
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.
The rigid and lightweight Mica Reinforced Cellular (MRC) speaker cone and dust cap contribute to the sound quality.
The layout of the side passive radiators has been optimized to reproduce clear bass sound.
