The L-Acoustics ARCS Wide is a professional, constant-curvature Wavefront Sculpture Technology (WST) passive line source loudspeaker designed for medium-throw applications. It belongs to the “ARCS WiFo” family alongside the ARCS Focus, optimized to create wide sound coverage with relatively few arrayed enclosures while maintaining a compact layout that preserves venue sightlines.

Key Specifications

The exact metrics and system boundaries from the official L-Acoustics Documentation are:

• Acoustical Design: 2-way passive system, housing a 12-inch weather-resistant low-frequency driver and a 3-inch diaphragm compression driver coupled to a proprietary DOSC waveguide.
• Dispersion Angle: Symmetrical 30° horizontal by 90° vertical coverage (compared to the narrower 15° x 90° of the ARCS Focus).
• Frequency Range: Operational bandwidth from 55 Hz to 20 kHz. It can seamlessly scale down to 32 Hz when integrated with the companion L-Acoustics SB18m subwoofer.
• Output Capabilities: Reaches a maximum sound pressure level of 135 dB (or up to 137 dB with optimized system presets).
• Power Handling: 450W RMS at a nominal impedance of 8 Ohms.
• Build Quality: Built from premium Baltic birch plywood with a gray-brown or pure white finish, featuring an integrated pole-mount socket and an IP55 protection rating. It weighs 36 kg (approx. 79.4 lbs)
