The d&b B4 Subwoofer is an actively driven cardioid subwoofer. It houses two long excursion neodymium drivers in an integrated cardioid setup. A 15″ front facing driver in a bass-reflex design and 12″ rear driver in a two-chamber bandpass design. The cardioid dispersion pattern resulting from this approach avoids unwanted energy behind the system that greatly reduces the reverberant field at low frequencies and provides the greatest accuracy of low frequency reproduction. The B4 subwoofer can only be used in a ground stacked setup. Suitable for hire for theatres, clubs or DJs.
