Driver Designed for Vocal Applications Including Mass Notification Systems, Voice Alarms, Emergency Evacuation Systems and Long-Distance Call to Prayer Loudspeakers.
Celestion, one of the worldʼs leading suppliers 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 aluminium voice coila tough, single piece polyimide diaphragmasurrounda plus finite element analysis (FEA) optimised 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 optimising 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.
