The d&b audiotechnik B4 is a compact cardioid subwoofer designed for precise, musical low frequencies with excellent rear rejection. Its single-cabinet cardioid topology pairs a forward-facing 15-inch driver with a rear-facing 12-inch driver to minimise stage spill and room build-up, delivering controlled, punchy bass without the complexity of multi-box arrays. Capable of up to 131 dB SPL from a practical 44 kg enclosure, the B4 delivers outstanding output-to-size performance for mobile events and fixed installations. Seamless integration within the d&b ecosystem ensures predictable voicing and straightforward control when paired with appropriate d&b amplification and processing.
This 2012 unit has been regularly maintained and remains a dependable choice for professional use. It includes a protective cover to help keep the cabinet in top condition between shows. Choose the B4 when you need focused, well-contained low end that enhances intelligibility, tidies the stage sound, and improves overall mix definition without adding complexity. Ideal for corporate presentations, theatres and live music venues.
