Overview
DVS 1.0 SERIES DVS 401
The DVS 401 is a coaxial surface-mount loudspeaker engineered to provide superb audio performance in both background and foreground music sound systems. Ideally suited for a wide variety of applications, from restaurants and hotels to houses of worship and businesses of all types, the DVS 401 offers the power handling, wide frequency response and low distortion typically found in more expensive products. EN 54-24 certification for fire detection and fire alarm systems makes the DVS 401 the perfect choice where safety is a top priority. The loudspeaker is also UL 1480 certified for fire-protected signalling.
Exceptional Sound and Reliability
The design comprises a 100 mm (4.00") polypropylene full-range driver and 0.79" ferrofluid cooled soft dome high frequency driver mounted in a UV and weather resistant UL 94-V0 ABS enclosure. Dust protection is provided in the form of an attractive aluminium mesh grille. The paper cone material and butyl rubber surround enhance durability and long-term reliability. DVS 401 is specifically designed for applications requiring the combination of excellent music and speech sound quality and exceptional reliability.
Weather-Resistant Enclosure
