L-Acoustics announces the new ARCS A15 and A10 systems and companion sub KS21, which deliver L-Acoustics concert performance and reliability for audiences from 50 to 5,000 in an approachable, compact format. With the launch of the new ARCS product range, L-Acoustics introduces a new charter agreement offering rental partners meeting the ARCS standard system requirements the opportunity to join the official L-Acoustics rental network.

The ARCS family comprises four constant curvature enclosures—A15 Focus, A15 Wide, A10 Focus, A10 Wide—and a dedicated subwoofer, KS21. ARCS enclosures offer flexible coverage options, achieving a throw of up to 45 meters, and an impressive maximum output of 144 dB. Mounted on a pole, stacked, or flown in a vertical or horizontal line source array, the new ARCS family comprises modular, plug-and-play ease and international market acceptance. This versatile solution, with configurable directivity, scales with the needs of the event and venue. 

A15 and A10 systems scale impeccably to events large and small: from weddings and galas, to the main system for a corporate event, theater, or mid-size festival stage with KS21 extending low frequency bandwidth to 30 Hz. At large events, ARCS becomes an effective fill or delay solution as a complement to larger K1 and K2 systems. 

“The flexibility that can be achieved with this new generation of ARCS is unprecedented,” explains Germain Simon, L-Acoustics Product Manager. “The mounting, stacking, and rigging options, combined with user configurable L-Fins to adjust waveguide directivity, gives users a large range of permutations to work with. For example, with only two ARCS elements, you can easily achieve 15 different coverage patterns.”

The plug-and-play simplicity of A15 and A10 Focus and Wide extends to amplification. The enclosures were designed with LA4X capabilities and 1-to-1 ratios in mind. Each LA4X amplification channel pairs with one A15, one A10, or one KS21. The 1-to-1 ratio extends to A15 and KS21, where one sub is recommended for each A15 enclosure. For A10, the recommended loudspeaker-to-sub ratio is 2-to-1. For further flexibility, ARCS also functions seamlessly with LA12X amplified controllers.

A15 and A10 feature integrated rigging that make deployment efficient and secure. The unique, patent-pending flush rigging reduces the chances of mishandling and excessive vibration, enhancing both safety and speed.
