d&b C4 and B2 Systems

What d&b say about C4 and B2:

The C-Series has been optimized for medium to large scale, flexible, modular array configurations and high sound pressure levels. The C-Series loudspeakers use horn loading and conventional point source techniques to create modular high power systems with different dispersion options. The cabinets share the same size, are arrayable and equipped with dedicated

rigging and transportation hardware. Light weight and compact sizes that take into account standard truck widths result in time, space and cost benefits when transporting and installing systems. Applications range from professional touring use and permanent installations down to single cabinet setups requiring narrow dispersion with minimum dimensions. The C loudspeakers are

designed for a wide range of applications with a clear perspective to provide mobile, flexible, configurable array solutions to the most arduous sound reinforcement situations. The d&b TransCalc calculator enables simple and accurate system planning. The Ci loudspeakers differ only in cabinet construction and mounting hardware. They are intended for

permanently installed performance spaces where the specification is rider driven by the artist or mix engineer’s preferences. Both the Ci cabinets and mounting hardware can be colour matched to interior designs and can provide protection in climatically hostile environments.

The B2-SUB is a dual mode 2 x 18” double band pass subwoofer, configurable either for infrabass with the C4 system or as a high output alternative subwoofer. When used with a C4 system, d&b recommend a ratio of four C4-SUBs to one B2-SUB.

The B2-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 at the top and bottom for securing an optional transport lid. The cabinet incorporates eight steel handles and four heavy duty wheels.

d&b C4 is a point source arrayable concert system comprising C4-Top which is a two way fully horn loaded mid / high box with 12" and 1.4" drivers crossed over passively, and C4-Sub which is an 18" horn loaded bass unit. On it's own the C4 system has a frequency range of 50Hz - 18kHz. To extend the low frequency response down to 32Hz the dual 18" B2 is used in "Infra bass" mode.

This is a very efficient and capable concert system easily scalable from venues of a relatively low capacity upwards. Black Box have both 2 wide and 3 wide flying systems available to complement these systems.

The C4 system can be used with d&b P1200 as well as D12 and D80 amplifiers.
