Here’s a technical guide for the system. Note: V-DOSC is a discontinued but still widely used line array. It was the industry’s first “Wavefront Sculpture” array, later replaced by K1/K2. l-acoustics v-dosc
The V-DOSC enclosure was engineered specifically to satisfy WST criteria while maintaining a practical form factor for touring. are possible with SB218 (front/rear facing pairs +
| L-Acoustics model | Benefit vs V-DOSC | |-------------------|---------------------| | | Higher SPL, extended LF, lighter | | K2 | Variable curvature, lighter, more flexible | | Kara II | Smaller, but similar bandwidth | | A15 (Focus/Wide) | Modern WST, much lighter, simpler rigging | l-acoustics v-dosc
The most critical component of the V-DOSC was the DOSC (Diffuseur d'Ondes Sonores Cylindriques) waveguide. Traditional high-frequency drivers utilize exponential horns that produce spherical wavefronts. The DOSC waveguide utilized a complex internal geometry to transform the spherical wave from the compression driver into a cylindrical isophase wavefront. This allowed the high frequencies to couple correctly with the drivers above and below in the array, extending the line source behavior into the high-frequency spectrum—something previous line arrays failed to achieve effectively.
