This 10 inch 8 ohm member of the NE family has leading-edge transducer technology packaged in a cutting edge, stylistic design. The subwoofers in this family feature an innovative cast aluminium basket design which minimizes acoustic reflections inside the driver, through large basket windows and sculpted basket spokes. The basket also is designed to act as a highly coupled heat sink to the NdFeB motor, so as to improve power handling capacity. An additional heat sink is available to provide extra thermal protection if needed. The cone and dust cap are constructed of natural wood fiber material with proprietary coating formulas & processes, so as to yield high clarity products. The cone designs also utilize pentacone technology for improved frequency response. The voice coil bobbin is titanium, for improved performance. The FEA-designed motor features copper caps to minimize inductance and extend performance to high frequencies. Rounding out the design is a 4-way terminal block connector, for ease of electrical connection.DC Resistance Revc Ohms 6.24 5.0% Energy Bandwidth Product EBP (1/Qes)*fs Minimum Impedance Zmin Ohms 8.03 7.5% Moving Mass Mms g 74.1 Voice Coil Inductance Le mH 0.53 Suspension Compliance Cms um/N 647.9 Resonant Frequency Fs Hz 22.97 15% Effective Cone diameter D cm 20.4 Mechanical Q Factor Qms 10.33 Effective Piston Area Sd cm^2 326.9 Electrical Q Factor Qes 0.31 Effective Volume Vas L 97.21 Total Q Factor Qts 0.3 Motor Force Factor BL Tm 14.7 Ratio Fs/Qts F Fs/Qts 76.57 Motor Efficiency Factor ß (T*M^2)/Ohms 34.6 Half Space Sensitivity @2.83V db@2.83V/1M dB 85.08 +/- 1.0db Voice coil former Material VCfm TiSV Half Space Sensitivity @1W/1M db@1W/1M dB 85.1 +/- 1.0db Voice coil inner diameter VCd mm 51.32 Gap Height Gh mm 8 Rated Noise Power P W 190 Maximum Linear Excursion Xmax mm 9.4 Test Spectrum Bandwidth 20Hz - 2kHz Ferrofluid Type FF Driver Size Inch 10 in Driver Mass Kg 2.27
