The L-Acoustics ARCS II is a constant curvature WST (Wavefront Sculpture Technology) line source enclosure designed for medium-throw applications. It features a 2-way active design with K1-grade drivers, providing high SPL and constant tonal balance over distance.
The system is designed to be arrayed either horizontally or vertically with a constant curvature.
- Rigging Hardware: Uses captive coupling bars. Specific accessories include the BUMP3 (lifting 2 or 4 units), LIFTBAR (for arrays of 1, 3, 5, or 6 units), and ARCBUMP (for vertical assemblies of up to 4 units).
- Amplification: Exclusively driven by L-Acoustics amplified controllers, primarily the LA8, LA4X, or LA12X, which provide the necessary factory presets and protection.
- Subwoofer Pairing: Often paired with the SB28 subwoofer to extend the low-frequency response down to 25 Hz.
