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.
