The ARCS II enclosure operates over the 50 Hz to 20 kHz nominal frequency bandwidth. This response can be lowered down to 25 Hz with the addition of the SB28 subwoofer.

The DOSC® HF waveguide generates a 22.5° symmetric x 60° asymmetric (-20°/ 40°) directivity pattern. These values correspond either to the horizontal x vertical coverage angles, for an ARCS II enclosure standing vertically, or to the vertical x horizontal coverage angles, for an ARCS II enclosure in the radial orientation.

The ARCS II rigging system allows assembling a horizontal or vertical array with a constant curvature. The DOSC® waveguide in the HF region allows the system to be arrayed without breaking the inter-element acoustic coupling. The WST® (Wavefront Sculpture Technology) criteria are then fulfilled, so that such an array can be qualified as a true line source. An ARCS II line source provides a smooth tonal response and a coverage that is free of secondary lobes over the entire frequency range.

The ARCS II enclosure is exclusively driven and bi-amplified by the LA8 amplified controller. This one ensures active system linearization, intelligent transducer protection, and optimization for the loudspeaker system. With a single factory preset designed to be used in the different operation modes of the ARCS II, the performance of the system will depend upon the choice of the physical system configuration.
