L-Acoustics KIVA Line Array Speaker
Modular line sources offer tremendous flexibility for both the installation market and rental applications. Both KIVA and KARA® systems are designed to combine a compact, high performance and lightweight enclosure with a dedicated companion LF extension (KILO, SB15m, SB18) delivering the necessary LF resources when a reinforced contour is desired.
- Long throw applications with clarity, intelligibility and precision
- Ultra-compact and lightweight, discrete integration
- 100° horizontal x up to 15° inter-element vertical flexibility
- LA4/LA8 control and protection
- Pole mount or KIBU-SB rigging options
- 40 Hz LF extension with SB15m for today’s music
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 fulfil 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.
