The d&b audiotechnik B4 is a compact cardioid subwoofer engineered for precise, musical low frequencies with excellent rear rejection. Its smart single-cabinet cardioid design pairs a forward-facing 15-inch driver with a rear-facing 12-inch driver to minimise stage spill and room build-up without the complexity of multi-sub arrays. Delivering up to 131 dB SPL from a practical 44 kg enclosure, the B4 offers superb output-to-size performance for mobile events and fixed installations alike. Seamless voicing within the d&b ecosystem ensures predictable results 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. A protective cover is included to help 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.
Choose the B4 when you need punchy, well-contained low end that improves intelligibility and mix definition without compromising stage sound.
