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.
