The CDD15-WR is a very high-power, weatherised, passive two-way system designed for outdoor installations that demand the ultimate in sonic performance from a single enclosure and suitable for applications where it will be subject to changing environmental conditions, but sheltered from direct exposure to the elements.

Features

  • 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
  • Integral inserts for eyebolt suspension
  • 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 CDD15-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 composite 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 CDD15 can be suspended by eyebolts or by means of an optional horizontal weatherised yoke.

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

A full-range, passive two-way system, the CDD15-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 Specs

CDD15-WR
Architectural Specifications

The loudspeaker shall be a passive, two-way system ultilising Coaxial Differential Dispersion technology. Its transducers shall consist of a reflex-loaded 15” low frequency driver with a water-resistant cone and a coaxially-mounted 1.4” 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 100° to 60° and vertical dispersion shall be 60°. The on-axis frequency response shall be 55Hz-18kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 132dB peak calculated at 1 metre. Power handling shall be 400W AES, 1600W peak. Rated impedance shall be 8 ohms.

The input connector shall be a low-profile 20A push-lock type with a waterproof cover incorporating a cable gland. Low and high frequency sections shall be integrated by an internal 1.6kHz passive network. For optimal performance 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 429mm x 691mm x 413mm (16.9in x 27.2in x 16.3in). Weight shall be 28.3kg (62.4lbs).

The loudspeaker shall be the Martin Audio CDD15-WR.
