The CDD8-WR is a weatherised ultra-compact two-way passive loudspeaker system suitable for outdoor applications where it will be subject to changing environmental conditions, but sheltered from direct exposure to the elements. It features 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-WR and CDD15-WR.

Features

  • Ultra-compact, CDD™ passive two-way system
  • Coaxial Differential Dispersion™ technology
  • Elegant UPM Formi composite enclosure
  • Outdoor operation when sheltered from direct exposure to elements
  • Operating temperature -20°C to +70°C
  • Environmentally tested to meet IP54
  • User-rotatable coaxial drive unit
  • Vertical and horizontal mounting options
  • Screw-free water and particle resistant grille
  • 8Ω nominal impedance
  • Discreet weatherised mounting accessories
  • Black or white standard colour options

Applications

  • Outdoor Restaurants
  • Bars
  • Hotel Areas
  • Nearfield Systems in Outdoor Stadia
  • Transport Hubs
  • Concourses and Theme Parks

The Coaxial Differential Dispersion technology employed in the CDD8-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 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 weatherised brackets.

CDD8-WR 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 .

Finished in black (RAL9005) or white (RAL9016) as standard.

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

Architectural Specifications

The loudspeaker shall be a passive, two-way system ultilising Coaxial Differential Dispersion technology. Its transducers shall consist of a reflex-loaded 8” low frequency driver with a water-resistant cone and a coaxially-mounted 1” exit high frequency compression driver. The HF driver shall be loaded by a static waveguide that merges with moving waveguides added to the cone of the low frequency driver to define the HF horn geometry.

The coaxial driver shall be user-rotatable to enable vertical or horizontal operation as required by the application. Horizontal dispersion shall vary from 110° to 80° and vertical dispersion shall be 60°. The on-axis frequency response shall be 70Hz-20kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 123dB peak calculated at 1 metre. Power handling shall be 200W AES, 800W peak. Rated impedance shall be 8 ohms.

The input connector shall be a low-profile 13A push-lock type with a waterproof cover incorporating a cable gland. Low and high frequency sections shall be integrated by an internal 2.3kHz passive network. For optimal the loudspeaker shall be operated in conjunction with a dedicated electronic controller.

The enclosure shall be made from rigid composite material and fitted with threaded inserts with stainless steel screws for wall and ceiling mounting. The drivers shall be protected by a powder coated, zinc plated steel grille with Declon® backing and a secondary grille with hydrophobic mesh. The loudspeaker shall meet the IP54 environmental rating.

Dimensions (W x H x D) shall be 256mm x 410mm x 252mm (10.1in x 16.1in x 9.9in). Weight shall be 9.8kg (21.6lbs).

The loudspeaker shall be the Martin Audio CDD8-WR.
