UNPACKING THE UNIT

Thank you for purchasing a Martin Audio CDD Series speaker system. Every Martin Audio

loudspeaker is built to the highest standard and thoroughly inspected before it leaves the

factory. After unpacking the system, examine it carefully for any signs of transit damage and

inform your dealer if any is found. It is suggested that you keep the original packaging so that

the system can be repacked at a future date if necessary. Please note that neither Martin Audio

nor its distributors can accept any responsibility for damage to any returned product which arises

through the use of non-approved packaging.

Please think of our environment.

When the product has reached the end of its useful life, please dispose of it responsibly through

a recycling centre.

INTRODUCTION

Thank you for purchasing this Martin Audio CDD loudspeaker system.

The Martin Audio CDD Series has been designed to fulﬁl the need for high performance sound in

pubs, bars, restaurants, retail premises, nightclubs, conference facilities, theatres, educational

institutions, places of worship, museums, exhibition centres and cruise ships, in an ultra-

compact package.

CDD speakers deliver the highest quality audio over a wide area, with consistent coverage

throughout the venue.

The cabinets are styled to be architecturally unobtrusive. CDD enclosures (except for the CDD5)

are constructed from rigid, moulded UPM Formi, a ﬁbre composite material combining stiffness

with excellent damping properties. The larger models (CDD8 upwards) have birch ply bafﬂes and

all models feature ﬂush, acoustically transparent steel grilles. Subwoofers are built in heavily

braced MDF enclosures. Enclosures come in either a white or black ﬁnish; with other RAL

colours available to order.

The CDD range of loudspeakers use two-way, full-range co-axial drivers, incorporating Martin

Audio’s exclusive Differential Dispersion horn technology. Passive crossovers optimised for the

drivers are ﬁtted, obviating the need for bi-amping. The crossover frequency is between 1.6 kHz

and 2.5 kHz, depending on model.

The CDD range consists of six full-range units, with drivers from 5” to 15”. These are supplemented

by a range of four CSX sub-woofers with single or dual 12”, or single or dual 18” LF drivers.

Systems may be used individually or in multiples to suit a wide variety of applications. Link

connectors are ﬁtted to facilitate daisy-chain wiring.

A version of the CDD5 is also available for 70/100 V-line operation. This model, the CDD5TX,

includes a high quality tapped transformer and a power setting switch, to allow the speaker

to be used with the 70 V-line or 100 V-line distribution systems used for announcements and

background music in ofﬁce complexes, hotels and similar large buildings.

A wide range of installation accessories is also available, permitting wall, ceiling or ﬂown mounting.

Mounting hardware is suitable for ﬁrst and second ﬁx construction industry conventions.

This User Guide provides a detailed explanation of the CDD’s features and options. Please take

the time to read through the Guide even if you are experienced with other Martin Audio products.

Thank you again for placing your conﬁdence in Martin Audio products.

CDD USER GUIDE

COAXIAL DIFFERENTIAL DISPERSION TECHNOLOGY

All CDD Series full-range models feature Martin Audio’s unique, patent-pending Coaxial

Differential Dispersion™ technology. CDD systems augment the ‘point-source’ beneﬁts of coaxial

drivers with the consistency of coverage which Differential Dispersion technology can deliver.

Non-coaxial systems can suffer from uneven frequency response in the crossover region because

of interference between the LF and HF sections; depending on the listening position, this causes

off-axis variations, particularly close to the loudspeaker. In contrast, coaxial systems aim to sum

LF and HF contributions at all positions off-axis, even close-up.

A disadvantage of conventional coaxial devices can be HF beaming, where the HF dispersion

reduces at higher frequencies. This is primarily because the HF energy emerges through a narrow

tube in the pole-piece of the magnet system. CDD Series coaxial devices overcome this by the

use of a static waveguide that merges seamlessly with the unique cone shape — maintaining the

dispersion pattern even at very high frequencies.

A Differential Dispersion horn has a trapezoidal dispersion pattern in both vertical and horizontal

planes which covers the target area more evenly than a system with a conventional, ﬁxed-

dispersion type horn. With a conventional 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 extending to all corners of the audience area, while wide horizontal coverage is achieved

very close to the loudspeaker. The consistency of frequency response and SPL thus achieved

throughout the audience area is exceptional. The improved coverage close to the source also

means that CDD speakers can often be spaced further apart, reducing overall speaker count.

CDD RANGE ACCESSORIES

Mounting accessories

Several mounting options are available for the various models in the CDD range. These may be

summarised as follows:

• Wall mounting – brackets are available for all models up to the CDD12.

• Ceiling mounting – brackets are available for Models CDD5, CDD6 and CDD8.

• Yoke assemblies – suitable for either wall or ceiling mounting - are available for Models

CDD10, CDD12 and CDD15.

• All models may be ﬂown using standard rigging procedures; eye bolts are available for

all models. Note that CSX subwoofers may also be ﬂown (see “CSX Series subwoofers -

installation” on page 39).

Brackets and yoke assemblies are available in black or white to match the standard enclosure

ﬁnishes.

NOTE: A venue with Martin Audio AQ Series speakers already installed may be easily upgraded

to CDD Series speakers, as the existing AQ Series wall and ceiling mounting brackets can be

retained and re-used; the mounting holes in the enclosure ﬁxing plates are compatible with the

CDD series.

CDD MOUNTING HARDWARE

WALL AND CEILING MOUNTING BRACKETS

All CDD Models up to CDD12 may be wall mounted. and models up to CDD8 ceiling mounted,

using the appropriate optional bracket. Brackets are available for most models, as summarised

on the previous page. (Note that Models CDD10, CDD12 and CDD15 may also be wall or ceiling

mounted using a yoke assembly – see page 11.)

All mounting brackets allow CDD enclosures to be mounted in either vertical (“portrait”) or

horizontal (“landscape”) orientation. See page 16 for important information regarding driver

rotation for use in horizontal orientation.

The wall mounting brackets include pan and tilt adjustments to permit optimum alignment,

while the ceiling brackets (CDD6 and CDD8) allow vertical tilt angle to be set. Brackets are

supplied with ﬁxing screws to secure the bracket to the cabinet. To help installers complete a

neat ﬁtment, the ﬁxing plate of all the brackets includes a 19 mm dia. cable access hole for the

connection(s).

NOTE: To assist with ﬁrst ﬁx installation, mechanical drawings and drilling templates for all

ceiling and wall mounting brackets may be found in the Technical drawings section of this

Guide, see page 57.

Model CDD5:

NOTE: Model CDD5 speakers are packed and shipped in pairs, complete with wall mounting

brackets ﬁnished in either black or white to match the speakers. (Note that CDD5s in custom

RAL colours will be supplied with black brackets.) No additional mounting hardware is required

if the speakers are to be wall mounted.

Ceiling bracket – Part Nos. CDDCB5B (black), CDDCB5W (white):

Model CDD5 speakers may alternatively be ceiling mounted using these optional brackets, which

mate with one part of the wall mounting brackets supplied with the speakers.
