Name: CDD5
Rating: 4.7 (23 reviews)

The CDD5 is a two-way passive micro speaker designed for discreet positioning in architectural installations — including bars, museums, foyers, concourses, exhibition centres and HoW. It features a unique, patent protected 5” (125mm) LF/0.7” (19mm) HF Coaxial Differential Dispersion driver in a rigid ABS moulded enclosure and is supplied with a dedicated omni-directional mounting bracket.

The Coaxial Differential Dispersion technology employed in the CDD5 delivers more consistent audience coverage than systems with fixed X° x Y° coverage patterns — projecting relatively more output to the rear of the audience to distribute sound evenly front-to-back, 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 in the crossover region associated with non-coaxial designs.

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 the supplied omni-directional bracket or an optional close-mount ceiling bracket.

Finished in black (RAL9005) or white (RAL9016) as standard, the CDD5 can be supplied in any RAL colour to order.

The CDD5TX-WR option incorporates a 70V/100V line transformer.

A full-range, passive two-way system, the CDD5 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.

Architectural Specs

Martin Audio CDD5

The loudspeaker shall be a passive, two-way system ultilising Coaxial Differential Dispersion technology. Its transducers shall consist of a reflex-loaded 5.25” low frequency driver and a coaxially-mounted 0.75” dome high frequency 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 120° to 90° and vertical dispersion shall be 80°. The on-axis frequency response shall be 100Hz-20kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 116dB peak calculated at 1 metre. Power handling shall be 100W AES, 400W peak. Rated impedance shall be 8 ohms.

The input connector shall be a low-profile 13A push-lock type. Low and high frequency sections shall be integrated by an internal 2.5kHz passive network. For optimal performance the loudspeaker shall be operated in conjunction with a dedicated electronic controller.

The enclosure shall be made from ABS 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 160mm x 230mm x 149mm (6.3in x 9.1in x 5.9in). Weight shall be 2.7kg (6lbs).

The loudspeaker shall be the Martin Audio CDD5.
