KIVAwavefront sculpture technology®m a n u f a c t u r e r o f p r o f e s s i o n a l s o u n d s y s t e m sapplicationsThe KIVA Line Source element has an operating frequencybandwidth from 80 Hz to 20 kHz and thisresponse can be increased to 50 Hz with the additionof the low frequency extension KILO cabinet.architectspecifications18KIVA features two 6.5’’ drivers in a bass-reflex tunedenclosure and a HF 1.5’’ diaphragm compressiondriver coupled to a DOSC waveguide for HF reproduction.The passive crossover network uses 2nd orderfilters with built- in phase compensation.The V-shaped coplanar transducer configurationgenerates a polar pattern coverage of 100° horizontallywith symmetric pattern control across the projectionaxis, without any conflicts over the entirefrequency range.The combination of coplanar symmetry and the DOSCwaveguide in the HF region allows the system tofulfil the 5 WST criteria, thereby allowing the wavefrontof a KIVA line source to be curved up to a maximumof 15˚ for each element without breaking theinter-element acoustic coupling.The captive diecast 3-point rigging system is fullyintegrated into the KIVA cabinet allowing up to 20elements or 12 KIVA and 4 KILO to be flown in accordancewith the manufacturer’s recommendations.The KIVA cabinet is made from a unique compositematerial with remarkable mechanical and acousticproperties very similar to Baltic birch plywood butwith the added benefit of a high immunity tomoisture.The KIVA enclosure is controlled and amplified usingthe delicated LA4 controller. The performance ofKIVA depends upon the choice of preset and physicalsystem configuration.specificationsL-ACOUSTICS specifications are based on measurement procedures which produce unbiased results and allow for realistic performance predictionand simulation. Some of these specifications will appear very conservative when compared with other manufacturer’s specifications. Allmeasurements are conducted under free field conditions and scaled to a 1 m reference distance unless otherwise indicated.Frequency response (-10dB)Usable bandwidth:Nominal directivity (-6dB)Horizontal:Vertical:80 - 20k Hz ‘‘Line Source’’ configuration100° Symmetric (500 - 18k Hz)Dependant upon number of elements and line sourcecurvatureBetween 0° and 15° inter-element anglesSPL max levels 1‘‘Full Range’’ mode: 120 dB (cont) 126 dB (peak) 1 x KIVA ([KIVA] preset)ComponentsLF:HF:Nominal impedance:2 x 6.5’’ weather-resistant1 x 1.5’’ diaphragm compression driver8 ohmsRiggingEntirely captive, high-grade steel certified for 20 KIVAor 12 KIVA and 4 KILO according to manufacturer’srecommendations 2Angle increments: 0, 1, 2, 3, 4, 5, 7.5, 10, 12.5, 15°1 Max SPL at 1m under freefield measurement conditions usingpink noise with specified preset and corresponding EQ settings.2 Installation guidelines are specified in the SOUNDVISIONsoftware designed to help with L-ACOUSTICS productPhysical data• W x H/h x D: 520 x 175/103 x 358 mm20.5 x 6.9/4 x 14.1 in• Weight (net): 13kg 28.7 lbs• Connectors: 2 x 4-pin NeutrikSpeakon• Material: composite sandwichstructure, zamac and steel• Finish: maroon-gray, RAL 8017• Front: plastic grill, black andacoustically neutral ‘‘Airnet’’ grill cloth• Rigging : integrated flying hardwareand handles (black epoxy paint)
