Installed Sound

CDD/CDD-WR Series

Passive Indoor and Outdoor Loudspeakers & Subs

The Definitive Dedicated Install Series

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.

WHERE TO BUY
The CDD Series: The Shape 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 —which when complemented by high-performance SX Series subwoofers cover practically all install applications. With the CDD Weather Resistant (WR) and Marine (MAR) variants, 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.

The enclosures are moulded from different materials for optimal performance and price efficiency. CDD5 is injected moulded ABS, with CDD6 through CDD10 moulded in rigid UPM Formi — a natural fibre composite material which combines stiffness with excellent internal damping properties. CDD12 and CDD15 are now moulded using birch plywood. All models feature sophisticated internal rib structures to reduce weight and increase rigidity, and for the CDD8 upwards, the speaker baffles are machined from birch ply. Finished in black (RAL9005) or white (RAL9016) as standard, the CDD series can be finished in any RAL colour to order.

When used with the DX4.0 controller or an iKON amplifier, there now enhanced DSP and FIR based pre-sets to deliver the absolute maximum performance and fidelity while limiter settings protect the integrity of the system.

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.

Conventional Coaxial Beamwidth
CDD Beamwidth (horizontal)

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 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-Weatherised
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.

CDD is also available to custom order as a Marine (MAR) variant, ideally suited to cruise ships and seaside resort applications.

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.
