The DVS 4 is based around a point-source driver design comprising a 4-inch mid bass driver with a coaxially mounted 19mm (0.75-inch) high frequency section mounted in a stylish injection moulded surface-mount enclosure manufactured from UV/weather resistant ABS material. The new device is certified for water and dust ingress protection to IP64 standard and is currently pending UL Listed status (UL-1480 and UL-2043) making it a perfectly capable performer in challenging interior areas such as swimming pools, saunas or work areas where unusually high levels of dust or moisture may be present, as well as most outdoor applications where extreme environmental or harsh weather conditions are not a typical concern. The highly durable and scuff resistant, high impact ABS enclosure is available in black or white painted finish and comes with integral mild steel grille designed with optimum aesthetic sensitivity in mind. A colour-matched steel mounting bracket is included, which fits easily to the device via finger-tightened plastic screw-nut on the top and bottom of the enclosure, and audio connection is via standard euroblock making installation a quick and hassle-free affair. Because of point-source driver design, the DVS 4 can be mounted vertically or horizontally without compromising the dispersion and coverage control, offering complete versatility where positioning is concerned. The DVS 4t model option is equipped with an internally mounted low insertion loss line transformer for 70V or 100V distributed sound applications. Wattage taps are configurable to the following settings via a rotary tapping switch, which is located on the back panel. 70 V systems: 30 W / 15 W / 7. 5 W / 3.75 W; 100 V systems: 30 W / 15 W / 7.5 W.
