When the V-DOSC technology was invented at L-ACOUSTICS in 1992 - the first modern line source system featuring the exclusive WST technology was created - it revolutionized the professional audio industry.  The company philosophy is to engineer high quality purpose-built products designed to address well-defined practical needs. The L-ACOUSTICS V-DOSC system, is based on three major technologies: the coaxial point sources for short throw applications (XT and P); the constant curvature WST line sources for medium throw applications (ARCS WIDE/FOCUS and ARCS II); and the variable curvature WSTline sources for longer throw applications (KIVA, KARA, KUDO, V-DOSC and K1). With the proprietary DOSC waveguide, the L-Acoustics V-DOSC system was the first line array to operate coherently across the whole audible frequency range. Technological innovation is at the heart of every L-Acoustics line source element, with specifically tailored DOSC waveguides for constant curvature arrays (ARCS systems) or variable curvature arrays (K systems).
