VLS 15 is a passive column array loudspeaker with a complement of 7x3.5" (89mm) LF transducers mounted in vertical array with an assembly of densely spaced 8x1" (25mm) HF transducers mounted co-axially over a section of the LF (in an intuitively engineered, super-imposed chassis). VLS Series is the first range of products to incorporate FAST™ (Focused Asymmetrical Shaping Technology), delivering unique acoustic performance benefits including asymmetrical vertical dispersion, gently shaping the coverage towards the lower quadrant of the vertical axis.<br><br>VLS 15 packages this performance in a slender and narrow profile, aesthetically refined, powder coated aluminum chassis with curved stainless steel grille; ensuring a sleek and ultra-discrete appearance. Like the other 2 models in the range, VLS 15 can be ordered in either black or white as standard, with custom RAL colors available.<br><br>The device is fully compliant with EN54 - 24 and IP65 rated for dust and water ingress, salt spray and UV resistant and subject to rigorous high/low operational temperature and humidity testing making VLS 15 suitable for both indoor and outdoor use. Mounting is made easy via supplied flying and mounting brackets. Specification and design is aided by the use of Ease Focus v2.0 software, a generic, intuitive and easy to use three-dimensional acoustic simulation software. The software and relevant tutorials are free to download from the Tannoy website. VLS 15 features an integrated low insertion loss line transformer, configurable to various tapings via rotary switch, for use in high voltage distributed audio systems (100/70V).
