Martin Audio CDD8 Passive Coaxial Differential Dispersion On-Wall Loudspeaker, 8-Inch

Martin Audio CDD8 Passive Coaxial Differential Dispersion On-Wall Loudspeaker, 8-Inch

The CDD8 is an ultra-compact two-way passive loudspeaker system with an integrated 8” (200mm) LF/1” (25mm) exit HF Coaxial Differential Dispersion driver which can be easily rotated for horizontal or vertical orientation depending on venue design requirements. Its small size gives no indication of its high output capability. As a stand-alone loudspeaker, it has a multitude of applications and can also be incorporated as an infill loudspeaker in distributed systems using larger CDD models, such as the CDD12 and CDD15.

The Coaxial Differential Dispersion technology employed in the CDD8 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 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 optional wall and ceiling brackets.

Finished in black (RAL9005) or white (RAL9016) as standard, the CDD8 can be supplied in any RAL colour to order.

A full-range, passive two-way system, the CDD8 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.
