Martin Audio brings engineering innovation to installed sound with CDD™ and its Weatherised and Marine editions— combining distinctive curved enclosures with Patent protected Coaxial Differential Dispersion™ technology to deliver class-leading performance, fidelity and coverage consistency to venues that demand the ultimate in cutting-edge technology and style at a commercial price that makes sense.
Now the best, just got better with additional transformer variants and new improved voicing settings.
Not surprisingly, CDD is Martin Audio’s best ever selling install series and has been deployed in the world’s leading bars, clubs, restaurants, hotels and houses of worship.
In contrast, coaxial systems can achieve ‘point-source’ summation of the LF and HF sections at all positions off-axis, even close-up. This is one reason that coaxial devices are often used for nearfield applications such as studio monitoring.
Significantly, until now one disadvantage of conventional coaxial devices has been high frequency beaming, where the high frequency dispersion reduces as the frequency increases. This is primarily because conventional coaxial devices channel high frequencies through a narrow tube in the pole-piece of the magnet system. CDD Series coaxial devices overcome this by incorporating an innovative static waveguide that merges seamlessly with the unique cone shape — maintaining the dispersion pattern out to very high frequencies.
With a conventional X° x Y° horn, the speaker is usually placed bove head height and aimed towards the centre of the audience. This produces an imperfect coverage pattern which misses out some areas — particularly side areas close to the loudspeaker.
In contrast, a CDD Coaxial Differential Dispersion system produces a rectangular coverage pattern to reach all corners of the audience, and wide horizontal coverage is achieved very close to the loudspeaker. Walking the room, the consistency in frequency response and SPL — both close to the loudspeaker and further back — is exceptional.
The improved coverage close-up also means that CDD speakers can be spaced further apart in some instances, reducing overall speaker count.
CDD loudspeakers in black or white are also available in weather-resistant form. Like many on the market, CDD-WR loudspeakers are designed for outdoor operation where it will be subject to changing environmental conditions, but sheltered from direct exposure to the elements. A selection of weather resistant SX Subwoofers are also available.
CDD-WR loudspeakers meet a rating of IP54 and feature a weatherised water resistant grille made from zinc plated mild steel with a powder coated finish.
Applications include outdoor restaurants, bars and hotel areas, and near field systems in outdoor stadia, transport hubs, concourses and theme parks.

It takes the weatherised model and upgrades both the grille and all metal work to stainless steel 316, and for CDD12 and CDD15 marine variants the cabinet is made from UPM formi instead of birch plywood.
