Jantzen Audio 000-5428 | 2,2 mH | 0,12 Ω | 3% | 14 AWG

The Jantzen Audio 000-5428 iron core coil with discs is a premium component designed for discerning audio enthusiasts and professional loudspeaker builders. This 2.2 mH inductor delivers exceptional stability and consistent performance, making it an ideal choice for crossover networks in high-fidelity speaker systems. Its robust construction ensures reliable operation in demanding audio applications, from home theatre setups to studio monitors and custom DIY speaker projects.

This coil excels in low-frequency crossover sections where precise inductance values are critical for accurate driver integration. The iron core design provides high inductance in a compact form factor, while the integrated discs minimise stray magnetic fields and reduce interference with nearby components. With a tolerance of just ±3%, this inductor guarantees repeatable results across production runs, essential for matched pairs or multi-way speaker systems.

Technical features include a 14 AWG wire diameter of 1.63 mm, offering an exceptionally low DC resistance of only 0.12 Ω. This minimises power loss and heat generation, preserving amplifier efficiency and signal integrity. The overall dimensions of 55 x 46 mm allow for straightforward mounting within enclosures. Jantzen Audio’s meticulous winding process ensures consistent inductance and low core losses, delivering transparent sound reproduction without coloration.

For crossover designs requiring reliable, high-quality inductors with tight tolerances and minimal resistance, this iron core coil represents an excellent choice. Its combination of precision engineering and robust materials ensures long-term performance in any serious loudspeaker project.
