Hertz SX 250D
- 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.
