In 1992, French physicist Dr. Christian Heil and L-Acoustics introduced the V-DOSC system. It was not merely a new cabinet design, but a fundamental rethinking of how sound propagates in large spaces. V-DOSC represented the first successful industrial application of Line Source theory in a modular, touring-friendly format, establishing the standard for modern concert sound systems.
| Preset Name | Use case | |-------------|-----------| | | Main PA, full-range | | V-DOSC L-DOSC/SUB | High-passed main (80 Hz) for use with SB218 | | V-DOSC L-DOSC FILL | Downfill section (less LF) | | V-DOSC L-DOSC FF | Far-field-only array | | SB218 V-DOSC SUB | Subwoofer preset | l-acoustics v-dosc
While V-DOSC has since been succeeded by newer L-Acoustics models (such as the K1, K2, and ARCS series) that offer greater power-to-weight ratios and wider frequency response, the fundamental physics of the V-DOSC remain the industry standard. It proved that sound reinforcement could be treated as a rigorous scientific discipline rather than an art of approximation. In 1992, French physicist Dr
The release of V-DOSC catalyzed a complete overhaul of the touring industry. Within a decade, the "point-source cluster" became obsolete for major concert touring. Competitors quickly adopted similar line source principles, leading to the "Line Array Wars" of the late 1990s and early 2000s. The release of V-DOSC catalyzed a complete overhaul
Unlike traditional point-source speakers that lose 6 dB of sound pressure level (SPL) every time the distance doubles, V-DOSC generates cylindrical waves that only lose 3 dB per doubling of distance in the near field.
