L-Acoustics KIVA

Packaged in a fully integrated, ultra-compact design, L-Acoustics' KIVA fulfills the five WST (Wavefront Sculpture Technology) criteria in line with the scientific concepts introduced by the company in 1992, and is geared toward the fixed-install and rental production markets.

Packaged in a fully integrated, ultra-compact design, L-Acoustics’ KIVA fulfills the five WST (Wavefront Sculpture Technology) criteria in line with the scientific concepts introduced by the company in 1992, and is geared toward the fixed-install and rental production markets.

The main system components comprise the KIVA full-range element operating from 80 to 20k Hz bandwidth; KILO complementary low-frequency extension element operating from 50 Hz to 100Hz bandwidth; and LA4 amplified controller.

Using WST technology, KIVA allows for even coverage of extremely large acoustic environments where the number of elements (height of the array) constitutes the main factor in establishing the system throw, coverage pattern and directivity control parameters.

The V-shaped co-planar transducer configuration generates a fixed horizontal directivity of 100 degrees with symmetric pattern control across the projection axis. The combination of co-planar symmetry and the DOSC waveguide in the HF region allows the system to fulfill the five WST criteria, thereby allowing the wavefront of a KIVA line source to be curved from 0 to 15 degrees for each element without breaking the inter-element acoustic coupling.

Packaged in a lightweight and compact enclosure that sports a virtually invisible captive rigging system, KIVA combines quick setup and system integration with significant savings on storage and handling logistics. Due to its compact size (20.5×6.9×14.1 inches, W/H/D) and low weight (28.6 pounds), KIVA complies with stringent rigging limitations in theaters, performing art centers, concert halls, convention centers, sport facilities and TV/broadcast studios.

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

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

KILO is the low-frequency extension enclosure of the KIVA line source array system. Similarly featuring a modest size (20.5×13.9×14.1 inches, WxHxD) and weight (41.8 pounds), the cabinet is equipped with a single 12-inch neodymium driver in a tuned dual-chamber bass-reflex enclosure. The KILO enclosure generates an omni-directional coverage pattern. The addition of KILO elements within the line source array progressively polarizes coverage toward the front of the system as more elements are added, thereby increasing the directivity of the line horizontally and vertically due to natural dipole effects.

A three-point rigging system is captive and integrated into both the KIVA and KILO cabinets. Engineered and die-cast in high-grade steel, it allows up to 20 KIVA elements or 12 KIVA and four KILO to be flown in accordance with the manufacturer’s recommendations.

The KIVA and KILO enclosures are controlled and amplified by the dedicated L-Acoustics LA4 controller. A dedicated preset library designed for the LA4 platform optimizes system performance. A wide range of system configurations are available. Additional features include an intelligent two-way (real-time and RMS) transducer protection circuit and a unique contour EQ interface allowing instant contouring of the line source array.

The KIVA and KILO enclosures will both be available in May, while the LA4 amplified controller will be available in April.
