Two-Way 4" Co-axial Ceiling Loudspeaker for EN54-24 Applications

Control 14C-VA is a full-range, EN54-24 certified ceiling speaker consisting of a 100 mm (4 inch) high tech cone driver and a 19 mm soft-dome liquid cooled tweeter mounted in a vented, paintable baffle made of UV resistant UL94-V0 and UL94-5VB flammability-rated material, with a pre-attached blind-mount back-can for quick and easy installation. The speaker is designed to provide excellent sound quality for a wide variety of medium to high volume applications such as music cafes, business music systems, retail stores, music/paging systems, airports, reception/ waiting rooms, lounges, courtrooms, convention centres, hotels, educational facilities, and more. The speaker delivers consistent sound quality for listeners located both off and on axis.
