It wasn’t until 1992 when French company L-Acoustics introduced the V-DOSC, the first line array sound reinforcement loudspeakers, and changed the industry forever. Designed by company founder Dr. Christian Heil and his team, the system was based on the company’s Wavefront Sculpture Technology (WST) theory, which offered the first high-frequency device capable of creating a constant-phase planar output.

V-DOSC is an active full range 3-way loudspeaker enclosure that satisfies WST conditions when vertically arrayed. Each V-DOSC enclosure contains two direct radiating, bass reflex-loaded 15-inch low frequency transducers, four bass reflex-loaded 7-inch midrange frequency transducers that are mounted in a V-shaped acoustic lens configuration and two 1.4-inch exit, titanium diaphragm compression drivers that are coupled to individual, vertically-aligned DOSC waveguides. As a full-range system, the frequency response is 50 Hz to 18 kHz with less than ± 3 dB variation.

Complementing the V-DOSC enclosure is the dual-18 SB 218 subwoofer, which exactly matches V-DOSC’s 51.25-inch width and can be flown or ground-stacked to expand the system’s low-frequency performance down to 30 Hz.

Over the years, V-DOSC has been universally accepted on equipment riders for top touring artists and used in hundreds of installations worldwide.
