Celestion Introduces CDV1-1757 Compression Driver

Designed for optimum vocal clarity.

Dubai, U.A.E. (September 13, 2018)—In preparation for its appearance at the Pro Light + Sound Middle East show in Dubai later this month, Celestion introduces the CDV1-1757, a compression driver specifically designed for optimum performance across the critical vocal band.

This driver features Celestion technology built in, including a 1.75” (44mm) edgewound copper clad aluminum voice coil; tough, single-piece polyimide diaphragm/surround; plus finite element analysis (FEA) optimized magnet assembly and phase plug. This foundation enables the driver to deliver 120W continuous power handling (60Wrms, AES standard) and 107 dB sensitivity. A standard 1.38” (35mm) screw fitting provides maximum compatibility with a range of Celestion and third-party horn flares.

In a nod to the locale of the product’s debut, Celestion touts the CDV1-1757’s potential use in applications such as the broadcast of the Adhan, the Muslim Call to Prayer, where maximum clarity and intelligibility is demanded for the voice of the imam, with the capability to reach worshippers over the greatest possible distance.

“Pure vocal applications such as the Call to Prayer require a more application-specific approach to compression driver design,” said Celestion head of engineering Paul Cork. “By taking a fresh look at one of our existing designs—modifying the phase plug and optimizing the volume of the rear loading chamber—we were able to create a device that gave additional focus to the part of the frequency range where the voice sits. This led us to develop a driver with a greater vocal output level together with enhanced clarity.”
