B1-SUB
The B1-SUB is an actively driven subwoofer which uses a pair of
15" LF drivers mounted in a bass-reflex cabinet.
The B1-SUB cabinet is constructed from marine plywood and has
an impact resistant paint finish. The front of the loudspeaker
cabinet is fitted with a rigid metal grill covered with a replaceable
acoustically transparent foam, and fitted with catches to the top
and bottom for securing an optional transport lid E7909.
The cabinet incorporates four recessed handles, MAN CF4 stud
plate rigging points and on the rear panel are ratchet strap guide
plates (kelping bars) and four heavy duty wheels.
CAUTION!
Only operate B1-SUB c abinets with a d&b D12 amplifier in "Dual
channel" and B1-SUB mode or an A1 mainframe fitted with a B1-
SUB controller module, otherwise there is a risk of damaging the
