L-Acoustic (Booth C11908) has introduced two models of Constant-Curvature line source speakers. “WST” stands for Wavefront Sculpture Technology, where boxes can be used individually or in small arrays as a point-source solution, or arrayed with multiple units as a line source, without destructive interference effects.
The line source can be deployed either horizontally or vertically, with a coverage angle proportional to the number of enclosures in the array (N x 22.5 degrees). On the other plane—vertical or horizontal, respectively—the ARCS II line source provides an asymmetrical coverage angle of 60 degrees (20/40). The orientation of the ARCS II enclosures within the array determines asymmetric distribution, allowing the use of a horizontal ARCS II line source either for upward or downward coverage.
ARCS II can be quickly deployed as a tightly packed front of house system for medium throw applications with high-SPL LF impact and excellent stereo imaging. With precise and flexible coverage capability, the ARCS II is also well-suited for use as a distributed system, center cluster for theatrical work, sidefill monitoring, flown or stacked center fill, stereo front fill, offstage fill or delay system for concert audiences in stadiums and arenas.
The LA-RAK touring rack and LA8 amplified controller preset library deliver an extremely advanced and precise drive system for ARCS II. Additional features include the L-DRIVE intelligent two-way transducer protection circuit (Peak and RMS limiting) and unique Array Morphing EQ interface allowing the engineer to quickly adjust the tonal balance of the system to produce a reference curve or ensure consistency of the system’s sonic signature with multiple arrays of different types and sizes.
