Celestion Launches the CDX14-3040 Neodymium Magnet Compression Driver

	Celestion's CDX14-3040 Neodymium Magnet Compression Driver

At this year's Prolight + Sound in Frankfurt, April 10 - 13 (Hall 3.1, Stand B40), Celestion, a supplier of professional loudspeakers and compression drivers for sound reinforcement applications, is announcing the launch of the CDX14-3040 neodymium magnet compression driver. This brand new model utilizes a single-piece pure titanium diaphragm and surround -- together with a compact lightweight magnet assembly -- to deliver a superior high frequency performance.

The CDX14-3040 is a 1.4" exit, 3" voice coil neodymium magnet compression driver. It features a stiff and light edgewound coil copper clad aluminum voice coil and delivers 75Wrms (AES standard) power handling as well as a sensitivity of 106.5dB from 500Hz to 20kHz. Celestion recommends a minimum crossover frequency of 1kHz (at 12 dB/octave).

The CDX14-3040 is the third large format compression driver developed by Celestion to incorporate a 3" single-piece titanium diaphragm and surround, following the introduction of two ferrite magnet drivers: the 1.4" exit CDX14-3030 and 2" exit CDX20-3020.

Thanks to the lightweight neodymium magnet assembly, the CDX14-3040 offers a size and weight advantage over its ferrite magnet counterparts, weighing in at a modest 1.4kg/3.1lb at a diameter of 135mm/5.3".

"Celestion's engineers have applied advanced finite element analysis techniques, together with our unique, in-house loudspeaker modeling software, to create a device that further improves upon the performance of a design that has long been an industry standard," says Nigel Wood, Celestion managing director. "Our new CDX14-3040 reproduces the very high frequency performance of many popular large format titanium compression drivers while also offering a number of performance advantages such as lower distortion as well as reduced size and weight."

The design of all Celestion CDX compression drivers makes extensive use of the company's experience in finite element analysis (FEA) techniques to optimize the mechanical, acoustical, and electromagnetic design. This enables the development of products that offer outstanding performance whatever the HF application.
