The d&b audiotechnik B4 is a compact cardioid subwoofer engineered for tight, musical low end with minimal spill to the rear. Its integrated 15-inch and 12-inch driver arrangement creates a true cardioid dispersion pattern from a single cabinet, reducing stage bleed and room build-up without needing multiple subs. Delivering up to 131 dB SPL from a practical 44 kg enclosure, the B4 offers an impressive output-to-size ratio and swift deployment for mobile and installed systems alike. This unit originates from 2012 and has been regularly maintained, offering dependable performance in professional contexts. Seamless integration within d&b systems ensures consistent voicing and straightforward control, while the included protective cover helps keep the cabinet in top condition between shows. Ideal for corporate events, theatres and live music, the B4 is a smart choice where focused, controlled bass is essential without compromising clarity on stage or in the audience.
