TANNOY DVS4 BLACK ลำโพงติดผนัง Compact 4" Coaxial Weather Resistant Surface Mount Loudspeaker

The DVS 4 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 an aluminium 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.

Thanks to the 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 70 V or 100 V distributed sound applications. Wattage taps are configurable over a range of settings via a rotary tapping switch, which is located on the back panel.
