Martin Audio CDD12-WR

Two-Way Passive

12" Coaxial Differential Dispersion Driver (Weatherised)

The CDD12-WR is a weatherised compact, passive two-way system designed for installations that require high output levels suitable for outdoor applications where it will be subject to changing environmental conditions, but sheltered from direct exposure to the elements. Its high-specification 12” (300mm) LF /1” exit HF Coaxial Differential Dispersion driver delivers perfect sound across the audience over medium-throw distances. It features a water and particle resistant grille made from zinc plated mild steel with powder coated finish and is suitable for operating temperatures between -20°C to +70°C and environmentally tested to meet IP54.

The Coaxial Differential Dispersion technology employed in the CDD12-WR 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 LF driver has a 2.5” (65mm) voice coil and efficient motor with an aluminium demodulating ring to minimise distortion, while the HF driver utilises a 1.75” (44mm) polyimide diaphragm and features a low-compression phase-plug to reduce non-linearity.

The visually-distinctive birch plywood 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 curved shape of the CDD12-WR allows it to be surface-mounted close to a wall via an optional wall bracket or suspended from a ceiling by eyebolts or a horizontal yoke option. A full suite of weatherised accessories are available and fixings on the loudspeaker are stainless steel.

Finished in black (RAL9005) or white (RAL9016) as standard, with any RAL colour to order. A full-range, passive two-way system, the CDD12-WR should be used with a compatible controller with appropriate limiter settings to provide system protection.

When used with the DX4.0 controller or an iKON amplifier, there now enhanced DSP and FIR based pre-sets to deliver the absolute maximum performance and fidelity while limiter settings protect the integrity of the system.
