The L-Acoustics ARCS Wide is a constant curvature WST (Wavefront Sculpture Technology) enclosure designed to provide broad coverage with a high sound pressure level using a limited number of elements.
Key Features
- Wide Coverage: Optimized for medium-throw applications (approx. 30 meters) such as main FOH systems, central clusters, or side-fills.
- Scalability: Directivity can be scaled from 30° x 90° to 360° x 90° in 30° increments by adding enclosures to a horizontal or vertical array.
- System Integration: Often paired with the SB18m subwoofer to extend the low-frequency response down to 32 Hz.
- Environmental Protection: Features an IP55 rating (or IP45 in some documentation), making it moisture and weather-resistant.
Deployment and Rigging
- Horizontal Arraying: Uses the WIFOLIFT rigging bar for flying horizontal clusters of up to 4 units.
- Vertical Arraying: Uses the WIFOBUMP rigging frame for vertical arrays of up to 8 enclosures.
- Pole Mounting: Includes an integrated pole-mount socket (WIFOSOCK) for mounting a single enclosure directly on top of an SB18m or a standard tripod.
- Amplification: Driven by LA4X or LA8 amplified controllers, which provide essential linearization and protection
