Martin Audio CDD6 Ultra-Compact Coaxial Differential Dispersion Speaker

£684.00£976.80 inc.VAT

The ultra-compact CDD6 is a two-way passive loudspeaker system designed to fulfil the requirement for full-frequency dynamic performance from a very small enclosure. Featuring a 6.5” (165mm) LF/1” (25mm) HF Coaxial Differential Dispersion driver, its extremely small size and sleek lines make it ideal for visibly-unobtrusive applications.

It can also be used as a fill system in conjunction with larger CDD Series models and, with the addition of a CSX subwoofer, can reproduce surprisingly high levels of music program.

The Coaxial Differential Dispersion technology employed in the CDD6 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 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 optional wall and ceiling brackets.

Finished in black (RAL9005) or white (RAL9016) as standard, the CDD6 can be supplied in any RAL colour to order.

A full-range, passive two-way system, the CDD6 should be used with a compatible controller with appropriate limiter settings to provide system protection. The EQ and limiter functions of a controller such as the Martin Audio DX0.5, DX4.0 or an iKON amplifier will maximise its capabilities

When used with a CSX Subwoofer, crossover and EQ functions can either be performed by the DX0.5 or DX4.0 or iKON amplifier.

Architectural Specs

The loudspeaker shall be a passive, two-way system ultilising Coaxial Differential Dispersion technology. Its transducers shall consist of a reflex-loaded 6.5” low frequency driver and a coaxially-mounted 1” 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 110° to 80° and vertical dispersion shall be 80°. The on-axis frequency response shall be 80Hz-20kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 119dB peak calculated at 1 metre. Power handling shall be 150W AES, 600W 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 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 210mm x 325mm x 210mm (8.3in x 12.8in x 8.3in). Weight shall be 5kg (11lbs).

The loudspeaker shall be the Martin Audio CDD6.
