Why it mattered

01
Commercialized a repeatable full-frequency line-source system governed by Wavefront Sculpture Technology.
02
Made array geometry, rigging, processing presets, and prediction part of one deployment method.
03
Kennedy's FOH survey records that from 1995 Jeffrey Cox held North American rights to V-DOSC, having enclosures built by R&R Cases and doing wiring, final assembly and QC himself in Southern California.

Engineering record

Configuration: Each active three-way enclosure used two 15-inch LF drivers, four 7-inch MF drivers, and two 1.4-inch HF drivers feeding DOSC waveguides.[1]
Array geometry: Inter-element vertical angles were adjustable to five degrees, with 90-degree horizontal coverage.[1]

Original pricing

Not calculated without a reliable original price.

V-DOSC was delivered as a system with rigging, processing, amplification, and training rather than a simple retail box.

Use in the field

V-DOSC's 1992 arrival accelerated worldwide adoption of line arrays for professional touring.[2]

Professional reactions

Later field experience · 2004

Pakulski reported excellent results from a four-zone PA combining V-DOSC, dV-DOSC, fills and subs, using D5 onboard processing and XTA crossovers. His enthusiasm was for the complete touring chain, not an isolated loudspeaker test.
