* THE CDD SERIES: THE SHAPE OF THINGS TO
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 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
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™
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
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.
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.
Martin Audio CDD5
* 2-way passive
* 5" Coaxial Differential
The CDD5 is a two-way passive micro
speaker designed for discreet positioning in architectural
installations — including bars, museums, foyers, concourses,
exhibition centres and HoW. It features a unique, patent-pending 5”
(125mm) LF/0.7” (19mm) HF Coaxial Differential Dispersion driver in
a rigid ABS moulded enclosure and is supplied with a dedicated
omni-directional mounting bracket.
The Coaxial Differential Dispersion
technology employed in the CDD5 delivers more consistent audience
coverage than systems with fixed X° x Y° coverage patterns —
projecting relatively more output to the rear of the audience to
distribute sound evenly front-to-back, 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 in the crossover region
associated with non-coaxial designs.
The visually-distinctive 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
enclosure allows it to be surface-mounted close to a wall or ceiling
by means of the supplied omni-directional bracket or an optional
close-mount ceiling bracket.
Finished in black (RAL9005) or white
(RAL9016) as standard, the CDD5 can be supplied in any RAL colour to
order. The CDD5TX option incorporates a 70V/100V line transformer.
A full-range, passive two-way system,
the CDD5 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
