Celestion announced the launch of the CDX14-3030; a new 1.4-inch exit, ferrite magnet compression driver at the Prolight+Sound/Messe in Frankfurt. (Hall 8.0, Stand J78)

With a 3-inch copper clad aluminum voice coil driving a titanium diaphragm, the device delivers 75 watts (RMS) power handling and 106.5 dB sensitivity across a frequency range of 500 Hz to 18 kHz. Recommended minimum crossover frequency (at 12 dB/octave) is 1 kHz.

According to Celestion head of engineering Paul Cork, “This compression drivers bring together the best elements of technology used in the most successful products of our CDX range. The design extracts the maximum performance from a unit that is surprisingly compact for a 1.4-inch-exit device.”

Like other CDX compression drivers in the range, CDX14-3030 makes extensive use of Celestion’s experience in Finite Element Analysis (FEA) to optimize magnetic and acoustic design, helping the device to achieve top performance at a highly competitive price point.

This new driver also use Celestion’s proprietary Sound Castle diaphragm clamping assembly to ensure even clamping pressure on the diaphragm surround, while actively reducing stress on the diaphragm during operation. This contributes to lower distortion while enabling the full internal volume of the rear cover to act as a loading chamber for the diaphragm, resulting in superior mid-band response.

With exceptional heat management, plus an edge-wound coil copper clad aluminium voice coil the CDX14-3030 is a high performance HF solution for a wide variety of larger format sound reinforcement applications.
