Celestion Introduces CDX14-3060, 1.4-inch Exit Ferrite HF Compression Driver

Celestion, a pioneer in the development of professional loudspeakers for almost ninety years, announces the launch of the CDX14-3060 1.4-inch exit, high performance Ferrite magnet compression driver.

Ipswich, United Kingdom, September 08, 2012 --( With a 3” copper clad aluminium voice coil driving a titanium diaphragm, the device delivers 75Wrms power handling and 106 dB sensitivity. The CDX14-3060 additionally incorporates a number of advanced technology features to minimise distortion and enhance overall performance.

Principal among these is Maximised Modal Suppression (MMS), consisting of a major new design of phase plug and diaphragm, intended to greatly reduce levels of high frequency distortion.

View for more detailed information.

The phase plug was developed at Celestion’s UK headquarters from a patented design by Head of Group Research, Mark Dodd. It completely re-defines the criteria by which the physical dimensions of a compression driver’s phase plug are calculated, superseding the conventional method which is now more than 50 years old.

Working together with the new phase plug is a deep-drawn titanium diaphragm: its shape is deeper than those of conventional compression driver diaphragms, which increases stiffness. The rolled polyimide diaphragm surround improves stiffness control; together these features contribute to a genuine reduction in distortion.

The newly designed phase plug and diaphragm also deliver a lower compression ratio, reducing air non-linearity and allowing for higher maximum SPL. They provide a curved coherent wavefront at the driver’s exit, thereby optimising the unit for horn-loading.

Celestion’s next generation of Sound Castle(TM) diaphragm clamping assembly has been created to actively reduce stress on the diaphragm during operation; yet another feature contributing to lower distortion, as well as ensuring even greater consistency of performance.
