L-ACOUSTICS introduced its KARA modular line source system and its SB18 high power compact subwoofer at Prolight + Sound 2010 in Frankfurt, Germany.
L-ACOUSTICS states that KARA's design was inspired by its K1 stadium system, promising reliable performance for the rental market. The KARA system features a compact size and lightweight enclosure complying with rigging and visual limitations and the complementary SB18 subwoofer for reinforced LF contour applications. Compared with its predecessor, KARA offers added LF resources for increased bandwidth and coherence, improved directivity control in the horizontal plane, vertical coverage capability and improved ergonomics thanks to an integrated rigging system and lighter weight.
With a horizontal directivity of 110 degrees and vertical inter-element variation up to 10 degrees, KARA is fully configurable to match any audience geometry. Using the characteristics of Wavefront Sculpture Technology (WST), KARA promises clarity, precision and a unique proximity effect.
L-ACOUSTICS’ LA-RAK touring rack and LA8 amplified controller preset library deliver an advanced and precise drive system for KARA. A wide range of system configurations to accommodate various LF contour requirements and integration constraints are available for the sound designer and system engineer.
L-ACOUSTICS SB18 subwoofer
The SB18 is designed to complement L-ACOUSTICS’ WST (Wavefront Sculpture Technology) modular line sources and coaxial systems for applications requiring an extension of bandwidth with a flat to reinforced LF contour. Drawing on the latest innovations in electro-acoustics, signal processing and components, SB18 promises exceptional performance while offering the engineer and sound designer numerous modes of operation for rental and fixed installation applications.
The main L-ACOUSTICS system components for LF extension and contour reinforcement are the SB18 subwoofer, with a low frequency limit of 32 Hz, and LA4 and LA8 (LA-RAK) amplified controllers.
The 18-inch transducers specifically designed for SB18 combine high excursion capabilities, low thermal compression and reduced distortion. The bass-reflex vents feature a progressive profile allowing laminar airflow and reduced turbulence noise, even at the highest operating levels. These combined properties contribute to the SB18's sonic qualities in terms of precision and musicality.
The SB18 design is based on a single 18-inch LF transducer integrated into a dual bass-reflex tuned enclosure to deliver both impact and high sensitivity. Its compact size, combined with superior damping characteristics, make it extremely well suited for compact FOH applications. Therefore, L-ACOUTICS recommends the SB18 for use with KARA (either coupled/flown or stacked configurations), KIVA, ARCS and coaxial LF contour reinforcement in both standard and cardioid modes.
L-ACOUSTICS states that KARA and SB18 will undergo a pilot phase until June 2010 with a handful of rental companies that will collaborate closely with L-ACOUSTICS’ R&D team and technical support to validate rigging, system setup and preset libraries. The system is then scheduled to ship in September 2010.
