Wavecor WF166TU02 6-1/2″ Paper Cone Mid-Woofer 4Ohm

Wavecor WF166TU02 6-1/2″ Paper Cone Mid-Woofer 4Ohm Quick Overview:The Wavecor WF166TU02 is a 6-1/2″ paper cone mid woofer that is designed for demanding bass and midrange applications. This driver is powered by a large magnet structure that ensures good efficiency. The WF166TU02 is an ideal choice for car audio applications. Product Highlights:Very rigid die cast alu chassisBuilt-in alu field stabilizing ring for reduced high-level distortionVented voice coil former for reduced distortion and compressionVented chassis for lower air flow speed reducing audible distortionHeavy-duty black fiber glass voice coil bobbin to increase power handling and reduce mechanical losses resulting in better dynamic performance and low-level detailsLarge motor system with 1” voice coil diameter and large 90 mm magnet for better control and efficiencyLinear suspension with specially designed CONEX damper (spider) for long durability under extreme operating conditionsGold plated terminals to prevent oxidation for long-term reliable connection – important in a car environment Product Description:The Wavecor WF166TU02 is a 6-1/2″ paper cone midwoofer that is designed for demanding bass and midrange applications. This driver is powered by a large magnet structure that ensures good efficiency. The WF166TU02 is an ideal choice for car audio applications.The large motor system with 1-1/4” voice coil diameter and large 90 mm magnet for better control, power handling, and efficiency. The optimized paper cone ensures wide bandwidth and low distortion. Distortion is further reduced by efficient venting of chassis and voice coil. The Wavecor WF166TU02 is an obvious choice for 2-way high-end car speaker systems. Product Specification:  ParameterBefore burn-in After  burn-inUnitNominal size6.5[inch.]Nominal impedance4[ohm]Recommended max. upper frequency limit3.5[kHz]Sensitivity, 2.83V/1m (average SPL in range 200 – 2,000 Hz)91[dB]Power handling, short term, IEC 268-5, no additional filteringN/A[W]Power handling, long term, IEC 268-5, no additional filteringN/A[W]Power handling, continuous, IEC 268-5, no additional filtering60[W]Effective radiating area, Sd139[sq.cm]Resonance frequency (free air, no baffle), Fs50N/A[Hz]Moving mass, incl. air (free air, no baffle), Mms12.5[g]Force factor, Bxl5.0[N/A]Suspension compliance, Cms0.81N/A[mm/N]Equivalent air volume, Vas22.3N/A[lit.]Mechanical resistance, Rms0.40N/A[Ns/m]Mechanical Q, Qms9.8N/A[-]Electrical Q, Qes0.50N/A[-]Total Q, Qts0.48N/A[-]Voice coil resistance, RDC3.2[ohm]Voice coil inductance, Le (measured at 10 kHz)0.23[mH]Voice coil inside diameter32[mm]Voice coil winding height11[mm]Air gap height5[mm]Magnet weight400[g]Total unit net weight excl. packaging1.15[kg]Krm109[μohm]Erm0.97[-]Kxm2.04[mH]Exm0.79[-]Wavecor WF166TU02 DATA SHEET
