L-Acoustics Arc

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 WavefrontSculptureTechnology® (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.For touring applications, as a complementary 2-way fill
enclosure ARCS is ideal for sidefill monitoring due to its tight,
well-defined directivity pattern. When used in conjunction with V-DOSC or dV-DOSC FOH systems, ARCS is highly suitable for flown or stacked centre fill, stereo front fill, offstage fill or delay system
applications. When combined with L-ACOUSTICS SB218 or dV-SUB subwoofers, ARCS delivers powerful, extended bandwidth reproduction with additional low frequency impact that is perfect for FOH use in medium-sized venues. For FOH applications, the modular horizontal
directivity of ARCS allows for excellent stereo imaging in the standard left-right format while the flexibility provided by
asymmetrical vertical coverage allows the sound designer to cover virtually any room geometry. For more demanding FOH applications, ARCS can be used in a double row configuration with top row cabinets oriented in the normal position for up-fill and bottom row cabinets inverted for downfill. When arrayed in this manner, all 15'' loudspeakers satisfy WST criteria and couple over their entire operating bandwidth, providing maximum low frequency impact and throw due to enhanced directivity control at lower frequencies.
