KIVA - Modular WST Line Source

The KIVA Modular Line Source element has an operating frequency bandwidth from 80 Hz to 20 kHz and this response can be lowered downto 50 Hz with the addition of the KILO low frequency extension cabinet.

KIVA features two 6.5’’ drivers in a bass-reflex tuned enclosure and a 1.5’’ diaphragm compression driver coupled to a DOSC® waveguide for HF reproduction. The passive crossover network uses 2nd order filters with built-in phase compensation.

The V-shaped coplanar transducer configuration generates a symmetric horizontal coverage of 100° without secondary lobes over the entire frequency range.

The combination of coplanar symmetry and DOSC® waveguide in the HF region allows the system to fulfill the 5 WST® criteria, thereby allowing the wavefront of a KIVA line source to be curved up to a maximum of 15˚ for each element without breaking the inter-element acoustic coupling.

The captive 3-point rigging system is fully integrated into the KIVA cabinet allowing up to 20 elements (or 12 KIVA and 4 KILO) to be flown in accordance with the manufacturer’s recommendations.

The KIVA cabinet is made of a unique composite material with remarkable acoustic properties (very similar to Baltic birch plywood) and with the added benefit of a high immunity to moisture.

The KIVA enclosure is driven by the dedicated LA4 amplified controller. The performance of KIVA 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.

Modular line sources offer tremendous flexibility for installation and rental applications. Both KIVA and KARA®(i) systems are designed to combine a compact, high-performance and lightweight enclosure with a dedicated companion LF extension (KILO, SB18(i)) delivering the necessary LF resources when a reinforced contour is desired.

“My initial impression of the KIVA-KILO system was simply ‘wow’. I was extremely impressed, both with what I saw and heard. The arrays are small, compact, and lightweight enough to hang from the hall’s cantilevers as a single-point hang. One of my bosses commented on how sexy he thought these curvy cabinets looked, and it’s true that they are very visually appealing, but their audio far exceeds their visual appeal.”
