IntroductionIntroductionHow to use this manualThe Kiva II owner's manual is intended for all actors involved in the system design, implementation, preventive andcorrective maintenance of the Kiva II system. It must be used as follows:1. Read the technical description for an overview of all system elements, their features, and their compatibilities.• Electro-acoustical description (p.10)• Rigging system description (p.13)2. Prepare the system conguration. Consider the mechanical limits and the available acoustical congurations.• Mechanical safety (p.24)• Loudspeaker congurations (p.26)3. Before rigging the system, perform mandatory inspections and functional checks.• Inspection and preventive maintenance (p.31)4. To deploy the system, follow the step-by-step rigging instructions and refer to the cabling schemes.• Rigging procedures (p.52)• Loudspeaker connection (p.83)The Corrective maintenance (p.87) section contains the operations authorized for the end userPerforming another operation exposes to hazardous situations.For advanced maintenance, contact your L-Acoustics representative.As part of a continuous evolution of techniques and standards, L-Acoustics reserves the right tochange the specications of its products and the content of its document without prior notice.

The Kiva II features two 6.5" speakers in a bass-reex cabinet and a 1.75" diaphragmcompression driver loaded by a DOSC waveguide and L-Fins.Kiva II features an outstanding SPL/format ratio thanks to the excursion and power capability of the transducers. Theamplier density is maximized with 16 Ω impedance.The Kiva II operates from 70 Hz to 20 kHz. The coplanar transducer arrangement and the new K front grill producea 100° symmetric horizontal directivity output with a smooth tonal response free of secondary lobes over the entirefrequency range. In accordance with the WST coupling criteria to preserve the wave front coherency, the maximum inter-element angle is 15°.The internal passive crossover network uses custom lters. The L-Acoustics amplied controllers ensure the linearizationand the protection of the transducers (L-Drive).The cabinet is made of a new composite material, with a high immunity to moisture and shocks and remarkable acousticproperties. Kiva II weighs a mere 14 kg (31 lb) and its compact elegance makes for an easy integration in any situation.Available in white or custom RAL CLASSIC, it melts into any architecture. The enclosure is rated IP55. The ush-ttedrigging features a visual safety check.Kiva II is particularly suited to multi-channel L-ISA systems in performing art centers or for sound reinforcement of specialevents. These xed installations or rental projects demand an impactful and immersive sound system yet with a compactfootprint to give room for either video displays, visual effects or preserve the architectural aspects of the venue.Kiva II can be own as a standalone system or with the SB15m. Under-balcony, pole-mount and pullback arrangementsare also possible.Kiva II owner's manual (EN) version 1.0 7
