A four inch copper wire voice coil with very high thermal capability and a ventilated magnet assembly allows a low power compression. A very low distortion figure is obtained using a double spider design and dual demodulation rings in the magnetic path. Proprietary water-proof cone treatment for safe use in adverse climatic conditions. £ 0 w o a co Specifications Nominal Diameter 460 mm (18 in) Nominal Impedance 8 Q Minumum Impedance 6.1 Q Power Handling (40 -400 Hz) Nominal1 100
Very smooth response from 400 Hz to 8 kHz. An aluminium phase plug increases axial sensitivity and controls high frequency dispersion. k O *
