	Celestion CDV1-1757 Compression Driver

Celestion, a supplier of professional loudspeakers and compression drivers for sound reinforcement applications, announces the availability of the CDV1-1757 compression driver. The CDV1-1757 is designed for optimum vocal clarity across the critical vocal band, which makes this driver especially well-suited to applications such as mass notification systems, voice alarms, and emergency evacuation systems as well as long-distance call to prayer loudspeakers.

The new CDV1-1757 delivers enhanced performance in the vocal range for superb clarity and intelligibility. The 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 enables the driver to deliver 120W continuous power handling (60Wrms, AES standard) and 107dB sensitivity. It features a next- generation proprietary Sound Castle diaphragm clamping system for superb reliability, even in the most demanding of applications.

"Pure vocal applications require a more application-specific approach to compression driver design," says 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 the CDV1-1757, a driver with a greater vocal output level together with enhanced clarity."

A standard 1.38" (35mm) screw fitting on the CDV1-1757 provides maximum compatibility with a range of Celestion and third-party horn flares.
