PRECISION TRANSDUCERS - Oktava

DRIVERND3020-T3Professional High Frequency TransducerThe ND3020T3 is a high performance 3.0-inch diaphragm compression driver witha 2 inch exit throat featuring several state of the art technologies. The diaphragmand suspension are precision formed from .05 mm thick pure titanium. Thesuspension is based on an innovative design using progressive parabolic semicircles.PART NUMBER 15120009Features3-inch Diaphragm, 2.0-inch Exit Throat/ Pure TitaniumCompression Driver220 watt Continuous program power handlingFrequency range: 500Hz - 20kHzDirect Drive“ Voice Coil Assembly3-slot, optimized geometry phase plugAluminum rear cover featuring an advanced ventedfin heat dissipation designCopper inductance ring for extended responseVented, damped, low distortion, variable profilesuspension SystemApplicationThe ND3020-T3 is the ideal driver for professional highperformance applications, from high power 2-way systemsto multiple-way long throw systems and large formatline arrays.General SpecificationsExit Throat DiameterRated ImpedancePower handling capacity 1continuous program above 1.2 kHzAES above 1.0 kHzSensitivity 1 W, 1 M, on axis, on horn 2Frequency Range 3Diaphragm MaterialSuspension MaterialSuspension DesignMinimum ImpedanceVoice Coil DiameterVoice Coil MaterialVoice Coil Former DesignNumber of layersBL FactorFlux DensityPhase Plug DesignPhase Plug MaterialMagneticsVoice Coil DemodulationMounting Information50.8/ 28220110109500 - 20000Pure TitaniumPure TitaniumProgressive9.3 ohm at 3700 Hz74.4/3.0Edgewound AluminiumDirect drive - Nomex1 - Outside13.12.053 slotAluminiumNeodymiumCopper ringmm/inchohmWattWattdBHzmm/inchT · mTOverall DiameterOverall HeightMounting4 x 6 mm threaded holes at 90 deg.Net WeightShipping Weight139/5.599.5/3.9101.6/4.03.4/7.53.7/8,1mm/inchmm/inchmm/inchkg/Lbskg/Lbs120316110100SPL, 1w/1m (dB)1009010Impedance (ohm)Notes to Specifications1. Continuos pink noise power ratings are derived from suggested AES standards sending a pink noisesignal having a 6 dB crest factor with a high pass filter set at the specified lower limiting frequency fortwo hours. Continuos program power is a conservative power rating for reproduction of typical audioprogram material.2. Sensitivity measurement is based on pink noise signal with input power of 1 watt and measured at 1meter from the mouth of a horn with a Q of 15 on axis and averaged between 2 and 5 kHz.3. Frequency range is defined as the measured frequency response -10dB relative to the rated sensitivity.801100 1.000 10.000 20.000Frequency (Hz)Frequency response and electrical impedance curve of the compression driver mounted on H6040 horn with inputsignal of 2.83 Volt.50020.0007020 100 1.00010.000 20.000
