1. High magnetic permeability plates provide constant, even flux. 2. Large double magnet, for perfect control under high power, very high excursion conditions for high SPL performance. 3. Four-layer aluminium voice coil; for unheard-of thermal capability. 4. Back plate venting holes, for optimal thermal dissipation. 5. Back vented spider support; for perfect symmetry under high excursion while providing increased thermal dissipation. 6. High-current, screw terminals, for large gauge wires. 7. Tinsel lead wires are integrated in the spider; for maximum reliability and conductivity. 8. Double wide-wave, resin-bonded fibre spider; for consistent parameters and reliability. 9. High density foam surround; for linear movement, even under extreme excursion. 10. Water-repellent, pressed paper cone. 11. Aluminium ring within the pole piece reduces impedance modulation at high excursion.
