The KiVA is the main element of a modular WST® line source with variable curvature.
The KIVA loudspeaker enclosure is based on a 2-way passive design with a nominal
impedance of 8 ohms. It features two 6.5" speakers in a bass-reflex tuned enclosure and
a 1.5" diaphragm compression driver coupled to a DOSC® waveguide. The transducers
are implemented in a V-shape configuration. The cabinet is made of a unique composite
material with remarkable acoustic properties, very similar to the ones of the Baltic birch
plywood, and with the added benefit of a high immunity to moisture. A 3-point rigging
system is integrated into the cabinet.
The KIVA operates over the nominal frequency range of 80 Hz to 20 kHz. This response
can be extended down to 50 Hz with the dedicated KILO extension or 40 Hz with the
SB15m subwoofer. The DOSC® HF waveguide generates a symmetric horizontal coverage
of 100°.
The KIVA rigging system allows vertically assembling the enclosures with various interenclosure angles, up to 15˚, therefore constituting a line array with variable curvature. The
combination of the coplanar symmetry and the DOSC® waveguide in the HF region ensure
a perfect acoustic coupling between the elements of an array. The WST® (Wavefront
Sculpture Technology) criteria are fulfilled, so that such an array can be qualified as a true
line source. Any WST® line source provides a smooth tonal response and a coverage that
is free of secondary lobes over the entire frequency range.
