L-Acoustics has introduced the ARCS A15 and A10 systems and companion sub KS21 to address audiences from 50 to 5,000, claiming ‘an approachable, compact format that offers unlimited versatility and ease of use’.

The ARCS family comprises four constant curvature enclosures (A15 Focus, A15 Wide, A10 Focus, A10 Wide) and the dedicated KS21 subwoofer. ARCS enclosures offer flexible coverage options, achieving a throw of up to 45m, and a maximum output of 144dB. 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.

‘The new ARCS family is a powerful concentrate of L-Acoustics technology, integrating best practices from across our entire product range and development history,’ says Director of Sound System Design, R&D, Christophe Combet. ‘Bended wood technology, inspired by our X Series, makes the new ARCS enclosures lightweight, yet incredibly sturdy. ARCS have configurable L-Fins for refining directivity. K2-grade speakers and drivers, the industry’s best available components, deliver our unmistakable sonic signature. And KS21, our first 21-inch sub, will exceed expectations as the best compact subwoofer in the market. The system has built-in ease of operation, right down to the flush-fitting rigging.’

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

The plug-and-play 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 1:1 ratio extends to A15 and KS21, where one sub is recommended for each A15 enclosure. For A10, the recommended loudspeaker-to-sub ratio is 2:1. 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.
