The CDD15B is a very high-power, passive two-way system designed for installations that demand the ultimate in sonic performance from a single enclosure. It combines very high output capability with exceptional fidelity and coverage consistency. Its coaxial drive unit comprises a powerful 15″ (380mm)/3″ (75mm) voice coil LF driver and a 1.4″ (35mm) exit HF compression driver with a 3″ (75mm) pure titanium diaphragm.
The Coaxial Differential Dispersion technology employed in the CDD15B delivers more consistent audience coverage than systems with fixed Xdeg x Ydeg coverage patterns – projecting relatively more output to the rear of the audience, while having wide horizontal coverage close-up. Its innovative CDD driver achieves “point source” summation of the LF and HF sections – eliminating off-axis variations in frequency response associated with non-coaxial designs. Improving on conventional coaxial designs, which can suffer from high-frequency beaming, the driver features a static waveguide that merges seamlessly with the unique cone shape – maintaining the dispersion pattern out to very high frequencies.
