ARCS ® WIDE WST
The ARCS ® WIDE is a constant curvature WST
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
Coupling bars allow arraying ARCS
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
®
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, LA8 or LA12X controller. These ensure system linearization,
®
protection, and optimization for the loudspeaker system.
WIFORIG COUPLING BAR
The WIFORIG is a coupling bar designed to be used in pairs to mechanically connect adjacent elements among the
following: ARCS ® WIDE enclosure, ARCS
®
® ARCS ® WIDE enclosure. The shipping carton should contain:
® ENCLOSURE
® enclosure. Within the ARCS
HF waveguide generates a 30° x 90° symmetric directivity pattern.
®
® WIDE enclosures as a line with constant curvature, either vertically or horizontally.
® FOCUS enclosure and WIFOBUMP rigging frame.
