Celestion announces the availability of the CDV1-1757 compression driver. The CDV1-1757 is designed for vocal clarity across the vocal band, which makes this driver 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 features Celestion technology built in, including a 1.75-inch (44mm) edgewound copper clad aluminium voice coil; tough, single piece polyimide diaphragm/surround; plus finite element analysis (FEA) optimised magnet assembly and phase plug. This enables the driver to deliver 120 watts continuous power handling (60Wrms, AES standard) and 107dB sensitivity. It features a next-generation proprietary Sound Castle diaphragm clamping system for 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-inch (35mm) screw fitting on the CDV1-1757 provides compatibility with a range of Celestion and third party horn flares.
