Description

The Coaxial Differential Dispersion technology employed in the CDD5 delivers more consistent audience coverage than systems with fixed X° x Y° coverage patterns — projecting relatively more output to the rear of the audience to distribute sound evenly front-to-back, 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 in the crossover region associated with non-coaxial designs.

The visually-distinctive 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 enclosure allows it to be surface-mounted close to a wall or ceiling by means of the supplied omni-directional bracket or an optional close-mount ceiling bracket.

Finished in black (RAL9005) or white (RAL9016) as standard, the CDD5 can be supplied in any RAL colour to order.

The CDD5TX-WR option incorporates a 70V/100V line transformer.

A full-range, passive two-way system, the CDD5 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 are 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.
