PL18WO09-08 - Tymphany

PL6½″ WooferType Number: PL18WO09-08Features:The PL series is designed for the discerning audiophile customer.To meet the needs of this audience, several new technologieswere developed with the goal of lowering distortion and dampingin the speaker. The coated paper cone reduces vibration andstanding waves, and the vented motor system minimizes powercompression. The combined result is a very open and dynamicsound.Driver Highlights: Magnesium Chassis, NRSC cone, NR rubbersurroundSpecs:Electrical DataNominal impedance Zn 8 ohmMinimum impedance Zmin -- ohmMaximum impedance Zo 43 ohmDC resistance Re 5.8 ohmVoice coil inductance Le 0.85 mHT-S ParametersResonance Frequency fs 38 HzMechanical Q factor Qms 2.46Electrical Q factor Qes 0.4Total Q factor Qts 0.34Force factor Bl 7.8 TmMechanical resistance Rms 1.75 Kg/sMoving mass Mms 17.5 gSuspension compliance Cms 1.02 mm/NEffective cone diameter D -- cmEffective piston area Sd 132 cm 2Equivalent volume Vas 25 ltrsSensitivity (2.83V/1m) 87 dBRatio BL/√(Re) 3.24Ratio fs/Qts F 112Power handling100h RMS noise test (IEC) -- WLong-term Max Power (IEC 18.3) 300 WMax linear SPL (rms) @ power -- dB/WShort Term Max power (IEC 18.2) 400 WVoice Coil and Magnet ParametersVoice coil diameter 40 mmVoice coil height 14 mmVoice coil layers --Height of the gap 6 mmLinear excursion +/- -- mmMax mech. excursion +/- -- mmFlux density of gap -- mWbTotal useful flux -- mWbDiameter of magnet -- mmHeight of magnet -- mmWeight of magnet 0.7 KgNotes:IEC specs refer to IEC 60268-5 third edition.All Tymphany products are RoHS compliant.
