The CDD12 is a compact, passive two-way system designed for installations that require high output levels. Its high-specification 12” (300mm) LF /1” exit HF Coaxial Differential Dispersion driver delivers perfect sound across the audience over medium-throw distances.

Features

  • Compact, CDD™ passive two-way system
  • Coaxial Differential Dispersion™ technology
  • Elegant UPM Formi composite enclosure
  • User-rotatable coaxial drive unit
  • Vertical and horizontal mounting options
  • Screw-free perforated steel grille
  • 8Ω nominal impedance
  • Discreet mounting accessories
  • Integral inserts for eyebolt suspension
  • Black or white standard colour options

Applications

  • Live Music Clubs and Bars
  • Nightclubs
  • Bars and Restaurants
  • Museums and AV Spaces
  • Convention Centres
  • Hotels
  • Retail Outlets
  • Leisure Centres
  • Houses of Worship

The Coaxial Differential Dispersion technology employed in the CDD12 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 LF driver has a 2.5” (65mm) voice coil and efficient motor with an aluminium demodulating ring to minimise distortion, while the HF driver utilises a 1.75” (44mm) polyimide diaphragm and features a low-compression phase-plug to reduce non-linearity.

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 curved shape of the CDD12 allows it to be surface-mounted close to a wall via an optional wall bracket or suspended from a ceiling by eyebolts or a horizontal yoke option.

Finished in black (RAL9005) or white (RAL9016) as standard, the CDD12 can be supplied in any RAL colour to order.

A full-range, passive two-way system, the CDD12 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 or DX2 system controllers, or by an MA Series amplifier with onboard DSP option.

Architectural Specs

CDD12
Architectural Specifications

The loudspeaker shall be a passive, two-way system ultilising Coaxial Differential Dispersion technology. Its transducers shall consist of a reflex-loaded 12” low frequency driver and a coaxially-mounted 1” exit high frequency compression driver 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 60° and vertical dispersion shall be 60°. The on-axis frequency response shall be 62Hz-20kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 128dB peak calculated at 1 metre. Power handling shall be 300W AES, 1200W peak. Rated impedance shall be 8 ohms.

The input connector shall be a low-profile 20A push-lock type. Low and high frequency sections shall be integrated by an internal 1.9kHz 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 for wall and ceiling mounting. The drivers shall be protected by a perforated steel grille with scrim cloth backing.

Dimensions (W x H x D) shall be 360mm x 571mm x 350mm (14.2in x 22.5in x 13.8in). Weight shall be 19.3kg (42.5lbs).

The loudspeaker shall be the Martin Audio CDD12.
