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.
