Ideal for medium-to-large rooms, the CDD15 is a very high-power, passive two-way system designed for installations that demand the ultimate in sonic performance from a single enclosure. It combines very high output capability with exceptional fidelity and coverage consistency. Its coaxial drive unit comprises a powerful 15” (380mm)/3” (75mm) voice coil LF driver and a 1.4” (35mm) exit HF compression driver with a 3” (75mm) pure titanium diaphragm.

Martin Audio CDD15
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 and a coaxially-mounted 1.4” 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 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. 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 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 429mm x 691mm x 413mm (16.9in x 27.2in x 16.3in). Weight shall be 27.7kg (61lbs).
The loudspeaker shall be the Martin Audio CDD15.
