The C3 is the hornloaded line array module for the d&b C4 system. With a horizontal dispersion of 35° (above 900 Hz) and a 5° vertical HF dispersion per cabinet, the C3 is used to build vertical columns producing a curved coherent wavefront to provide sufficient mid and high frequencies in distant listening positions. It is totally compatible with C4 loudspeakers utilizing an identical cabinet shape and rigging accessories. The C3 cabinet is constructed from marine plywood and has an impact resistant paint finish, steel handles and MAN CF4 stud plate rigging points. There are fittings at the top and bottom for securing an optional wooden lid, and mounted on the rear panel are ratchet strap guide plates, two hinge plates and four heavy duty wheels.
The d&b audiotechnik loudspeaker range is designed exclusively for operation with d&b amplifiers. These provide power as well as comprehensive control and protection functions tailored to achieve the performance, reliability and longevity associated with the d&b System approach. The d&b D12 and D80 amplifiers are recommended to drive the C3.
The 2-Way active C3 requires two channels of the D80.
