CDD Series

 

* THE CDD SERIES: THE SHAPE OF THINGS TO COME

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 in cutting-edge technology and style at a commercial price that makes sense.


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.


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. 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 combines the ‘point-source’ benefits of coaxial designs with the consistent coverage of Differential Dispersion technology. All CDD Series full-range models feature Martin Audio’s unique, patent-pending Coaxial Differential Dispersion™ technology to deliver perfect sound to every member of the audience.

 

* THE COAXIAL ADVANTAGE

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


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.

* 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 above 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-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.

 

 

Martin Audio CDD10

* 2-way passive

* 10" Coaxial Differential Dispersion Driver

 

The CDD10 is a very compact two-way passive loudspeaker system which utilises a 10” (250mm) LF/1” (25mm) exit HF Coaxial Differential Dispersion driver. It is uniquely placed to meet the foreground requirements of music bars and clubs, as well as the varied architectural applications that require upfront sound levels from a very compact enclosure. Use with a CSX118 or CSX218 subwoofer will enable the CDD10 to operate as small dancefloor system that is remarkably powerful for its size.


The Coaxial Differential Dispersion technology employed in the CDD10 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 composite 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 CDD10 allows it to be surface-mounted close to a wall via an optional wall bracket or suspended from a ceiling by eyebolts or a horizontal yoke option.


Finished in black (RAL9005) or white (RAL9016) as standard, the CDD10 can be supplied in any RAL colour to order.


A full-range, passive two-way system, the CDD10 may be used without a controller. However, the EQ and limiter functions of a controller such as the Martin Audio DX0.5, DX1.5 or DX2, or an MA Series amplifier with onboard DSP will maximise its capabilities. When used with a CSX subwoofer, crossover and EQ functions can either be performed by the DX0.5, DX1.5 and DX2 system controllers, or by an MA Series amplifier with onboard DSP option.
