L-Acoustics ARCS WiFo Set

The L-Acoustics ARCS WiFo system is a highly efficient, scalable constant curvature line source solution, designed to deliver clear, consistent audio coverage for a wide range of live sound and installation applications. The WiFo series combines the ARCS Wide and ARCS Focus enclosures—hence the name “WiFo”—to provide flexible deployment configurations tailored to venue size, shape, and audience distribution. Whether used individually, in horizontal or vertical arrays, or as part of a larger distributed system, the ARCS WiFo maintains L-Acoustics’ signature clarity, output, and sonic consistency.

Each ARCS Wide enclosure provides a 90° x 30° dispersion pattern, making it ideal for short- to medium-throw applications where wide horizontal coverage is essential. The ARCS Focus, by contrast, delivers a tighter 15° vertical by 90° horizontal dispersion, concentrating sound energy for longer throws or when more control is required. Both units feature a 12″ LF driver and a 3″ diaphragm compression driver mounted on a DOSC waveguide, providing a smooth transition between lows and highs and excellent speech intelligibility. The cabinets are powered by L-Acoustics’ LA4X or LA8 amplified controllers, ensuring precise system calibration, loudspeaker protection, and optimized performance. The system supports ground-stacked, pole-mounted, and flown configurations, offering significant adaptability for touring, theatrical productions, corporate events, or fixed installations.

The L-Acoustics ARCS WiFo system is widely used in venues where predictable coverage and quick setup are critical. It’s ideal for medium-sized theaters, houses of worship, conference halls, live clubs, and outdoor events. The ability to mix and match ARCS Wide and Focus units allows system designers to tailor the sound coverage precisely to the geometry of the space. Its modular nature, ease of rigging, and reduced footprint make it especially appealing for mobile production companies and venues seeking a scalable yet high-performance sound reinforcement solution. With its versatility and superior sound quality, ARCS WiFo remains a go-to choice for professionals who need both flexibility and fidelity.
