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.
