B2 subwoofer
The B2 is d&b's largest subwoofer and with its high
output bandpass horn design and extremely high SPL
it is ideal for extended bass requirements. It is
configurable to be either an infrabass for the C4 system
or a high output, alternative subwoofer for the F1222
or C7 systems. When used with a C4 system, d&b recommend
a ratio of four C4-SUBs to one B2. The B2 cabinet is constructed
from marine plywood, has an impact resistant paint finish and eight
integral steel handles. The front of the subwoofer cabinet is fitted with catches at the sides
for securing an optional transport lid, and mounted on
the rear are four heavy duty wheels.
Amplifiers
The B2 is driven by d&b's D12 dual channel amplifier configured for the B2.
More detailed information on specific loudspeaker setups with d&b amplifiers
is available either in the relevant loudspeaker or amplifier manuals.
