Martin Audio brings engineering innovation to installed sound with the all-new CDD™ Series combining distinctive curved enclosures with unique Coaxial Differential Dispersion™ technology to deliver class leading performance, fidelity and coverage consistency to venues that demand the ultimate.

Whether it’s a bar, an AV installation, a church or a prestige nightclub the CDD Series has it covered.

The CDD Series has the audience covered too. Coaxial Differential Dispersion technology delivers more consistent audience coverage than systems with fixed dispersion X° x Y° horns projecting more output to the rear of the audience to distribute sound evenly front-to-back, while having wide horizontal coverage close-up. The increased coverage area can reduce the speaker count in larger installations.

Visually-appealing enclosure design is a signature of the Series. The full range enclosures can be used in either horizontal or vertical orientation, with rotation of the coaxial driver easily accomplished by removing the screw-free, protective grille. The curved shape of each full-range enclosure allows it to be discreetly mounted close to a wall or ceiling.

With the exception of CDD5, all the enclosures are moulded in rigid UPM Formi a composite material which combines stiffness with excellent internal damping properties. From the CDD8 upwards, speaker baffles are machined from birch ply and all models feature sophisticated internal rib structures to reduce weight and increase rigidity. Finished in black (RAL90095) or white (RAL9016) as standard,can be supplied in any RAL colour to special order.
