Martin Audio CDD15W 15" Passive Speaker

The CDD15W 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 CDD15 delivers more consistent audience coverage than systems with fixed X° x Y° 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.

The visually-distinctive composite enclosure can be used in either horizontal (landscape) or vertical (portrait) orientation, with rotation of the driver easily accomplished by removing the screw-free, protective grille. The CDD15 can be suspended by eyebolts or by means of an optional horizontal yoke.

A full-range, passive two-way system, the CDD15 may be used without a controller. However, the EQ and limiter functions of a controller such as the Martin Audio DX0.5, DX1.5 or DX2, or an MA Series amplifier with onboard DSP will maximise its capabilities. When used with a CSX subwoofer, crossover and EQ functions can either be performed by the DX0.5, DX1.5 and DX2 system controllers, or by an MA Series amplifier with onboard DSP option.
