How does the C3 work?
The C3 is the long throw extension for the d&b C4 system. It comprises two 10″ hornloaded mid-range devices accompanied by a vertical array of three 1.3″ HF drivers loaded on a cylindrical wave transformer to give a 35 x 5° dispersion (5° wave segment). It is driven by a d&b D12 in 2-way active mode with the C3 configuration selected. Two C3s can be flown vertically with 0° – 5° vertical splay giving a maximum total vertical coverage of 10°, and a cylindrical wave segment in the HF band above approximately 2 kHz. This is the exact frequency region that larger C4 arrays with close-coupled C4-TOPs cannot project coherently.
