Celestion cdx1-1415 Brochura

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.
