KIVA - Modular Line Source

KIVA establishes a new reference in line source technology.

The system is offered as a modular package featuring the ultra-compact KIVA enclosure and the KILO LF extension.

KIVA delivers the ultimate performance with a compact footprint for fixed installation and rental production markets and complies with rigging and visual limitations in theatres, concert halls, convention centers, sports facilities and TV/broadcast studios.

Utilizing the unrivalled characteristics of WST^®, KIVA delivers clarity, precision and intelligibility for vocal material with a unique near-field perception offering an incomparable listening experience. When combined with KILO, KIVA delivers an extended bandwidth with increased LF impact suited to music.

KIVA combines extremely quick set up and system integration with significant savings on storage and handling logistics. KIVA can also be implemented in pairs in distributed systems with a directivity of 30 x 100°.

The new LA4 preset library makes it sonically compatible with all other L-ACOUSTICS^® systems.

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.
