Description

Cardioid subwoofer

The B4-SUB is an actively driven cardioid subwoofer powered by a single amplifier channel. It houses two long excursion neodymium drivers in an integrated cardioid setup: a 15″ driver in a bass-reflex design facing to the front and a 12″ driver in a two chamber bandpass design radiating to the rear. 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.
The B4-SUB can be driven either by the d&b D6 or D12 dual channel power amplifiers configured for the B4-SUB. More detailed information on specific loudspeaker setups with d&b amplifiers is available either in the relevant loudspeaker or amplifier manuals.

Amplifiers
The d&b D20 and 30D amplifiers are recommended to drive the B4-SUB. The d&b D80, 10D and D6 can also be used.
