Celestion announced the worldwide availability of the CDV1-1757 compression driver. The CDV1-1757 was designed for optimum vocal clarity across the critical vocal band, which makes this driver especially well suited to applications such as mass notification systems, emergency evacuation systems as well as long-distance call to prayer loudspeakers. It features a next- generation proprietary Sound Castle diaphragm clamping system for improved reliability, while a standard 1.38” (35mm) screw fitting provides maximum compatibility with a range of Celestion and third party horn flares.
Celestion announced the worldwide availability of the CDV1-1757 compression driver. The CDV1-1757 was 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. It features a next- generation proprietary Sound Castle diaphragm clamping system for improved reliability, even in the most demanding of applications. A standard 1.38” (35mm) screw fitting provides maximum compatibility with a range of Celestion and third party horn flares.
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 ferrite magnet assembly and phase plug. This enables the driver to deliver 120W continuous power handling (60Wrms, AES standard) and 107dB sensitivity. Celestion recommends its use with minimum crossover frequency at 800Hz (12dB/oct).
“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.”
