Introduction

The ARCS WIDE is a constant curvature WST enclosure. Within the ARCS WIDE and FOCUS family, it is designed to generate a wide coverage with few arrayed elements. The ARCS WIDE loudspeaker enclosure is based on a 2-way passive design with a nominal impedance of 8 ohms. It features one 12" LF speaker in a bass-reflex tuned enclosure and one 3" diaphragm compression driver coupled to a DOSC waveguide. The cabinet is made of first grade Baltic birch plywood for optimum acoustical and mechanical integrity. A pole-mount socket receptacle is integrated into the cabinet and allows mounting the enclosure on top of an SB18m subwoofer. The ARCS WIDE operates over a nominal frequency range of 55 Hz to 20 kHz. This response can be extended down to 32 Hz with the SB18m subwoofer. The DOSC HF waveguide generates a 30° x 90° symmetric directivity pattern. Coupling bars allow arraying ARCS WIDE enclosures as a line with constant curvature, either vertically or horizontally. The DOSC waveguide in the HF region allows the system to be arrayed without breaking the inter-element acoustic coupling. The WST criteria are then fulfilled, so that such an array can be qualified as a true line source. Any WST line source provides a smooth tonal response and a coverage that is free of secondary lobes over the entire frequency range. The ARCS WIDE is driven and amplified by the LA4X or the LA8 controller. These ensure system linearization, protection, and optimization for the loudspeaker system.
