As the market leader in premium professional sound systems, L-Acoustics takes pride in developing pragmatic solutions that enable audio professionals and artists to elevate the audience experience. True to this mission, the new ARCS A15 and A10 systems and companion sub KS21 deliver renowned L-Acoustics concert performance and reliability for audiences from 50 to 5,000 in an approachable, compact format that offers unlimited versatility and ease of use. 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.
In commenting the design of the new ARCS products, Christophe Combet, L-Acoustics Director of Sound System Design, R&D enthuses, “The new ARCS family is a powerful concentrate of L-Acoustics technology, integrating best practices from across our entire product range and development history. 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” 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 for sleek integration.”
Simplicity of design and deployment along with affordability, make the new ARCS range an ideal point of entry into the L-Acoustics network of rental partners. As new ARCS owners grow in capacity and knowledge, including via L-Acoustics training programs, the highly modular ARCS solution expands to accommodate larger projects.
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 plethora 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.
“A version of ARCS has been part of the L-Acoustics product line since 1995,” relates Christophe Combet. “It was the first loudspeaker reference to launch after V-DOSC revolutionized the industry. The philosophy behind the successive iterations of ARCS has always been to offer a superior, medium-throw, compact solution that is also easy to use. I am very proud that our new ARCS range raises the standard on all of these things in an impressive value-for-money package.”
“We see the new ARCS line of products as the perfect way to welcome providers into the L-Acoustics rental network,” shares Germain Simon. “The versatility and scalability of ARCS is really a ‘choose your own adventure’ scenario that only leads to happy endings. We look forward to seeing new customers approach the live events market in creative ways that allow them to capitalize upon their initial investment quickly and take their rental business to the next level.”
