The d&b audiotechnik B4 is a compact cardioid subwoofer designed to deliver tight, controlled low-frequency performance with minimal spill to the rear. Using an integrated 15-inch/12-inch driver arrangement, it achieves a cardioid dispersion pattern without the need for multiple cabinets, making it ideal for applications where stage bleed and room resonance must be kept in check. This unit presents in good cosmetic and technical condition, originally purchased in 2012 and regularly maintained. With a maximum SPL of 131 dB and a practical 44 kg form factor, the B4 offers excellent output-to-size ratio and efficient deployment for corporate events, theatres and live music. The included protective cover helps keep the cabinet in top condition between shows. Renowned for reliability and sound quality, the B4 integrates seamlessly into professional d&b systems and excels wherever precise, musical low end is required without compromising clarity on stage or in the audience area. A strong choice for rental inventories and fixed installs seeking focused bass reproduction.
