KILO - Low Frequency Extension

KILO is the Low Frequency extension of the KIVA line source array system. Operating from 50 Hz the cabinet features a single 12’’ neodymium driver in a dual-chamber bassreflex tuned enclosure.

The KILO enclosure generates an omni-directional coverage pattern. The addition of KILO elements within the line source array progressively polarizes the vertical coverage towards the front of the system (the horizontal directivity also increases due to natural dipole effects).

The 3-point captive rigging system allows flying up to 12 KIVA and 4 KILO with interelement angles from 0° to 15° in accordance with the manufacturer’s recommendations. Being entirely compatible with KIVA the line source can be built with a combination of both cabinets using the same rigging components.

The KILO enclosure is driven by the dedicated L-ACOUSTICS® LA4 amplified controller. The performance of a combined KIVA/KILO system depends upon the choice of preset and physical system configuration.

L-ACOUSTICS^® pioneered the field of modern line source array as early as 1993 with the introduction of Wavefront Sculpture Technology on the legendary V-DOSC^® system.

Based on physical rules developed by Heil and Urban (AES 1992) the WST^® theory defines five criteria for design and use of true line source arrays. At the heart of Wavefront Sculpture Technology is the internationally-patented DOSC^® waveguide, which morphs the spherical wavefront of the HF driver into a cylindrical, isophasic wave

In combination with WST^®, coplanar symmetry - the equivalent of coaxial assembly for HF, MF and LF drivers in vertical arrays - provides a coherent wavefront over the entire horizontal coverage at all frequencies. This behaves as if the sound was radiated by a single, continuous and articulated ribbon.

Any line source featuring L-ACOUSTICS^® elements respects the coplanar symmetry and all WST^® criteria on the entire sonic spectrum. This allows an exceptionally coherent sonic signature in very long throw applications, beyond the limits of other systems.

L-ACOUSTICS^® has been designing reference line array systems for more than 15 years.

ARCS® is a WST®-based constant curvature line source and can be incrementally arrayed in the horizontal or vertical planes to match any audience geometry. The system is optimized for medium-throw applications in theatres as a main stereo system or a radial central cluster. Its medium contour allows it to be implemented as a main FOH system in touring applications or as a fill system sonically compatible with large format line sources.
