Product Details CDD8-WR
CDD8-WR is a weatherised passive two-way Coaxial Differential Dispersion loudspeaker. The compact cabinet can operate independently or provide infill alongside larger CDD12 and CDD15 systems.
The 8-inch LF section works with a 1-inch-exit compression driver and polyimide HF diaphragm in the integrated coaxial assembly.
Coaxial Differential Dispersion provides wider horizontal coverage nearby and directs proportionally more energy towards the rear of the audience. LF and HF outputs combine as a point source, reducing the off-axis response changes around crossover associated with separated drivers.
A static HF waveguide merges with the shaped LF cone to maintain the intended pattern into the upper frequency range. This also addresses the high-frequency beaming that can occur in conventional coaxial arrangements.
The driver rotates for portrait or landscape operation after removing the screw-free grille. The curved composite cabinet accepts compatible wall and ceiling mounting accessories. Standard finishes are black RAL9005 or white RAL9016, with other RAL colours offered to order.
The weatherised design is intended for outdoor locations sheltered from direct exposure to the elements. It is tested to IP54 and for operation from −20°C to +70°C. The protective grille uses zinc-plated mild steel with a powder-coated finish to resist water and particles. Weatherised accessories and stainless-steel cabinet fixings support installation.
A compatible system controller supplies the correct equalisation and limiter settings for protection. DX4.0 or iKON provides enhanced DSP and FIR-based presets for the system; the passive loudspeaker requires suitable external amplification.
