Celestion Launches the CDX14-3040 Neodymium Magnet Compression Driver

Frankfurt, Germany (April 03, 2018) — At this year’s Pro Light + Sound (Hall 3.1, Stand B40), Celestion, one of the world’s leading suppliers 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-inch exit, 3-inch voice coil neodymium magnet compression driver. It features a stiff and light edgewound coil copper clad aluminium voice coil and delivers 75Wrms (AES standard) power handling as well as a sensitivity of 106.5 dB from 500 Hz to 20 kHz. Celestion recommends a minimum crossover frequency of 1 kHz (at 12 dB/octave).

The CDX14-3040 is the third large format compression driver developed by Celestion to incorporate a 3-inch single-piece titanium diaphragm and surround, following the introduction of two ferrite magnet drivers: the 1.4-inch exit CDX14-3030 and 2-inch 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/5.3in.

“Celestion’s engineers have applied advanced finite element analysis techniques, together with our unique, in-house loudspeaker modelling 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 industry-leading 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.
