L-ACOUSTICS® ARCS® provides the same performance benefits as V-DOSC® and dV-DOSCTM in a highly compact format suitable for both fixed installation and touring. By satisfying Wavefront Sculpture Technology® (WST) criteria, ARCS provides remarkable clarity and perfect coherence along with powerful, smooth, predictable coverage.

ARCS is designed for tightly-wrapped arraying in single or double row configurations or for horizontal arraying of up to 4 enclosures. The internationally patented DOSC waveguide designed exclusively for ARCS radiates a wavefront that has a radius of curvature matching the enclosure's 22.5° trapezoidal angle. When arrayed, the radiated constant curvature wavefront is continuous with an arc's shape with horizontal directivity equal to N x 22.5° (where N is the number of ARCS). Vertically, the exit of the DOSC waveguide is loaded by a cylindrical waveguide that provides an asymmetrical coverage angle of +40° by -20°. Modular horizontal coverage, combined with 60° vertical directivity, makes ARCS highly-suited to the overall coverage and throw distance requirements for typical medium-sized venues.

As a full range, two-way system ARCS can be used for front-of-house (FOH) sound reinforcement in corporate, television or theatrical applications. Due to its optimum speech reproduction and small physical footprint, ARCS is also highly effective as a flown center cluster for theatrical installations. For large-scale fixed installation, distributed arrays can be employed for stadium and arena sound reinforcement. In these applications, ARCS can be installed either single or arrayed, vertically or horizontally, and the precise, modular 22.5° horizontal directivity combined with the generous 60° vertical coverage allows for cost-effective coverage.
