The d&b audiotechnik B4 is a compact cardioid subwoofer designed for precise, musical low frequencies with excellent rear rejection. Its clever combination of a forward-facing 15-inch driver and a rear-facing 12-inch driver forms a true cardioid dispersion from a single cabinet, cutting stage spill and room build-up without deploying multiple subs. Capable of up to 131 dB SPL from a practical 44 kg enclosure, the B4 delivers a formidable output-to-size ratio, making it ideal for mobile and installed sound. Seamless voicing within d&b systems ensures predictable performance 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. The included protective cover helps keep the cabinet in top condition between shows. From corporate presentations and theatres to live music, the B4 provides focused, controlled bass that enhances clarity for performers and audiences alike.
Choose the B4 when you need punchy, well-contained low end that enhances intelligibility and mix definition without compromising stage sound.
