CDD/CDD-WR Series

Passive Indoor & Outdoor Loudspeaker & Subs

The Shape of things to Come

Martin Audio brings engineering innovation to installed sound with the all-new CDD™ and CDD Weatherised 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 in cutting-edge technology and style at a commercial price that makes sense.


CDD-LIVE! The Sha of things to come.


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


CDD is the one-stop solution with six two-way full-range coaxial systems — from the micro CDD5 to the powerful CDD15 —complemented by high-performance subwoofers able cover practically all install applications. Now with CDD-Weatherised option, those applications are extended even further.

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. This increased coverage area can reduce the speaker count in larger installations by up to 25% thereby significantly reducing total installation cost of a project.

Visually-appealing enclosure design is a signature of the CDD 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.

In summary, architects are happy with the discreet design and often fewer speakers; system integrators are happy as they can provide exemplary coverage for spaces and competitive tenders that increases the number of jobs that can be won; and the quality of coverage and consistency not only delights the client but also their clientele. No wonder, CDD is the shape of things to come.



COAXIAL DIFFERENTIAL DISPERSION™: THE BEST OF BOTH WORLDS 


CDD-LIVE! combines the ‘point-source’benefits of coaxial designs with the consistent coverage of DifferentialDispersion technology.


All CDD-LIVE! full-range models feature Martin Audio’s unique, patentedCoaxial Differential Dispersion™ technology to deliver perfect sound to everymember of the audience.



THE COAXIAL ADVANTAGE 


Non-coaxial systems can suffer from uneven frequencyresponse in the crossover region because the outputs of the LF and HF sectionsinterfere with each other, causing variations off-axis, depending on thelistening position. This is especially true close to the loudspeaker.


In contrast, coaxial systems can achieve ‘point-source’ summation ofthe LF and HF sections at all positions off-axis, even close-up. This is onereason that coaxial devices are often used for nearfield applications such asstudio 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-LIVE! 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.



THE DIFFERENTIAL DISPERSION™ ADVANTAGE


A Differential Dispersion horn has a 3D trapezoid dispersion pattern which covers a room more evenly than a system with a conventional, fixed-dispersion X° x Y° type horn.


With a conventional X° x Y° horn, the speaker is usually placed justabove head height and aimed towards the centre of the audience. This producesan imperfect coverage pattern which misses out some areas — particularly sideareas 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-LIVE! speakers can be spaced further apart in some installations, reducing overall speaker count, and similarly a reduction in frontfill / infill speakers in a live sound environment.


       



CDD-Weatherised

 

The CDD Series in black or white is also available in weather-resistant form. Like many on the market, CDD-WR loudspeakers and CSX-WR subwoofers are designed for outdoor operation where it will be subject to changing environmental conditions, but sheltered from direct exposure to the elements. Weatherised mounting brackets 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. CSX-WR subwoofers in the series are have an IP24 rating and feature a zinc plated mild steel grille with powder coated finish, plywood cabinets with polyurea finish and are flyable with stainless steel fixings.


Applications include outdoor restaurants, bars and hotel areas, and near field systems in outdoor stadia, transport hubs, concourses and theme parks.
