NTR
• Lightweight, high-performance drivers designed for high-end sound reinforcement applications.
• BL and stiffness (K) symmetry contribute to low distortion.
• Intelligent heat management reduces thermal compression, further minimising distortion.
• High temperature, copper, ‘Inside/Outside’ voice coils wound in-house.
• Rigid cast aluminium chassis for maximum mechanical integrity.
• Compact chassis design for space-efficient mounting in arrays.
• Extremely light weight design results in exceptional power-to-weight ratio.
Drawing on expertise gained in pioneering
the application of Neodymium magnet
structures to high-performance PA drivers,
the Celestion R&D team has created a new
range of high-end cast aluminium chassis
Neodymium drivers for professional sound
reinforcement applications – NTR.
With 6.5", 8", 10" and 12" models available
first in a range that will grow to include 15"
and 18" drivers, the new NTRs make
extensive use of Celestion’s advanced FEA
modelling techniques to achieve a number
of important performance advantages.
With particular focus on linear excursion via
optimised suspension geometry and magnet
topology, NTR provides application-specific
control delivering more low frequency
output, reduced distortion and increased
longevity.
In addition to BL and stiffness (K)
symmetry, NTR also achieves low thermal
compression and distortion through
intelligent heat management. Smart chassis
design combines with vented magnet
assemblies to dissipate heat quickly.
NTR also provides system builders with a
particularly high power-to-weight ratio, and
compact chassis designs well suited to
close mounting in arrays.

Typical of all high-end Celestion
professional drivers, the Ferrite magnet
FTR range combines linear excursion with
advanced heat management to achieve
low distortion and long product life.
Voice coils wound on both sides of a rigid
glass-fibre former cool more quickly
through greater contact with the air while
vented magnets and a smart chassis
design further enhance cooling efficiency.
The light weight, robust cast aluminium
chassis is designed to minimise reflections
back to the cone, significantly reducing
acoustic distortion, and an FEA optimised
magnet topology ensures even flux
distribution around the air gap.
New FTR HDX
New to the FTR range are long-throw 12",
15" and 18" drivers designed specifically
for subwoofer applications, featuring 4"
voice coils and double suspensions for

Providing a choice of flange or screw mounting devices, Celestion’s CDX range
has earned a reputation for performance and value among system builders.
Applying FEA to examine the behaviour of sound waves within a compression
driver has resulted in a phase plug design for the CDX 14 Series that
produces a more coherent wavefront at the driver exit.
The CDX-1430 incorporates an aluminium heat sink designed to conduct
heat rapidly away from the Neodymium magnet, achieving an impressive
50Wrms power handling from a driver weighing less than 500g.
34mm aluminium diaphragm
radiates from the convex side.
FEA modelling is used to achieve
the optimum balance of high SPL
with minimum distortion.
A two slot phase plug ensures that
wavefronts radiated across the
convex surface of the dome arrive
coherently at the horn throat.
The voice coil is wound directly onto the
‘skirt’ of the diaphragm, increasing
stiffness and improving cooling.
Elastomer suspension allows
long, smooth excursions for
reduced distortion and increased
driver life.

Custom Driver Development Services
• Highly experienced, UK-based R&D team for custom driver development.
• Strong track record in developing proprietary drivers that meet and exceed the performance and
budget requirements of the world’s leading system builders.
• Industry leaders in Finite Element Analysis.
• Equipped with cutting edge measurement and characterisation tools including Klippel®analysis and
one of the most advanced Loudspeaker Listening Facility available anywhere in the world.
• Sophisticated, secure on-line system for custom sample and data tracking.
At Celestion, our ‘off the shelf’ products are
just the beginning of the story. Based in the
UK, an experienced R&D team led by
Technical Director Ian White has earned an
enviable reputation for developing
proprietary loudspeakers that meet
precisely the very demanding requirements
of our OEM customers.
Following consultation with the
customer, the team uses Finite Element
Analysis (FEA) to model the behaviour
of virtual designs before committing to
physical prototypes, optimising the
choice of materials and driver design to
best meet performance and cost requirements. Pioneering users of FEA for the
prediction of motor distortion, mechanical and thermal properties, Celestion was the
first loudspeaker manufacturer to use FEA for vibro-acoustic modelling, and also to
predict magnetic inductance, subsequently combining these results with magneto-
static modelling to provide a complete, voltage-coupled model.
Celestion engineers enjoy access to one of
the best equipped loudspeaker design,
development, testing and measurement
facilities available anywhere in the world.
A drawing office equipped with the latest
CAD technology is located above a
laboratory which is itself fully equipped to
produce prototype designs, with direct
access to an anechoic chamber for
precision measurement and a power testing
room for ensuring long-term reliability.
Celestion engineers
make extensive use
of industry-standard
measuring
equipment including
a scanning laser
velocity meter, and
a Klippel®distortion
analyser to optimise
motor design, voice coil alignment and cone suspension in pursuit of BL and
stiffness (K) symmetry.
In addition to these sophisticated measurement facilities, Celestion’s R&D facility
also houses one of the world’s most advanced
loudspeaker listening rooms. Leading recording studio
designer Philip Newell has created a ‘room within a room’
– the outer chamber constructed from sand filled
concrete blocks to provide noise isolation while the inner
chamber incorporates the floating floor, membrane
absorbers and bass traps that apply the acoustic
treatment. The result is a controlled and perfectly isolated,
acoustically neutral environment for critical listening.
Throughout the
development,
sampling, measurement and production
engineering processes, customers are able
to track progress and data in a secure,
password-protected area on the Celestion
Professional website.
From a minor modification to an existing product through to a completely new
design, Celestion is equipped and resourced to provide system builders with
dependable, high-performance, cost-efficient loudspeaker drivers.
