Jantzen Audio 000-5436 | 0,47 mH | 0,058 Ω | 3% | 14 AWG

The Jantzen Audio 000-5436 iron core coil with discs is a premium component engineered for high-fidelity loudspeaker crossover networks. This 0.47 mH inductor delivers precise filtering to ensure clean frequency separation, allowing tweeters, midranges, and woofers to perform at their best without distortion or overlap. Its robust construction makes it ideal for both DIY audio enthusiasts and professional speaker builders seeking reliable, long-lasting performance in passive crossover designs.

This coil is particularly suited for low-frequency applications where accurate bass management is critical. Use it in two-way or three-way speaker systems to achieve a smooth roll-off and maintain phase coherence, or integrate it into custom equalisation circuits for subwoofers and full-range cabinets. The low DC resistance of just 0.058 Ω minimises signal loss and power dissipation, preserving amplifier efficiency and dynamic headroom even at higher volumes.

Technically, the coil is wound with 1.63 mm diameter wire (14 AWG) on a laminated iron core, which provides high inductance density and low magnetic leakage. The ±3% tolerance ensures consistent performance across production batches, while the compact 37 x 46 mm dimensions allow easy mounting on crossover boards. The included discs reduce eddy currents and further stabilise inductance, making this coil a reliable choice for demanding audio projects.

With its meticulous engineering and Jantzen Audio’s reputation for quality, this iron core coil is an excellent investment for achieving transparent, accurate sound reproduction in any high-end speaker system.
